It can be said that Zhao Chaogang's concerns are still very correct. If the shadow that came to the door of Mingzhu City Martial Arts Bar just now enters the Martial Arts Bar directly, then I am worried that there will be a sea of ​​blood in this Martial Arts Bar.

I believe that at this time you have already thought of who the shadow that appeared at the door of the Warrior Bar was, yes, the extraterritorial demon.

Someone will ask here, these extraterritorial demons have escaped abroad, why do they dare to return to China? You must know that there are powerful cultivators in China, and they are not afraid of being killed by these cultivators.

Haha, the reason is actually very simple, that is, there is a martial arts secret realm here in China, spiritual stones and spiritual energy required for cultivation, and the extraterritorial demons have now thoroughly understood the details of the earth.

The extraterritorial demons have been on earth for a long time. By constantly devouring human souls, these extraterritorial demons have fully understood some of the situations on earth. Therefore, the extraterritorial demons know very clearly that there are actually no cultivators on earth. Now the only place with cultivators is the only martial arts secret realm.

Even the secret realm of the martial arts world has just appeared. In addition, the concentration of spiritual energy equivalent to zero and the resource equivalent to zero on the earth, the extraterritorial demons have every reason to believe that there is no cultivator on the earth. Therefore, now, as long as these extraterritorial demons avoid the position where the secret realm of the martial arts world is, they can live without any scruples on the earth.

The spiritual energy and cultivation resources on the earth are too scarce, so even if there are countless cultivators in the Wulin Secret Realm. However, the possibility of these cultivators coming to the earth is zero. At most, the cultivation sects in the Wulin Secret Realm set up a garrison on the earth and stationed several people from the bottom of the sects.

This can not only show the existence of the sect of cultivation, but also recruit some seeds of cultivation on the earth.

In the eyes of the demons outside the domain, the only resource on earth that is useful to the cultivation sects in the martial arts secret realm is the population of more than 7 billion on earth.

If a sect of cultivation wants to pass on the inheritance, it is not enough to rely solely on the cultivation techniques and cultivation resources. It also requires enough seeds of cultivation, that is, disciples of cultivation.

It is an extremely important thing for a sect to continue to inherit the sects for a long time and to continuously supplement the personnel in the sects of sects, and it can even be said to be the most important thing. Without the addition of later personnel, no matter how powerful this sect is, it will only be a flash in the pan and will soon wither.

There is a population of more than 7 billion on the earth, which is enough for more than a dozen cultivation sects to use. If the earth is in the cultivation world, the demons outside the domain would not dare to walk around here openly, because there will be many cultivation here at that time, and the cultivation sects will attach great importance to the source of this population resource.

If the extraterritorial demons cause trouble in such a place, they will definitely seek death. The cultivation sect will send powerful cultivators to kill the extraterritorial demons as soon as possible.

However, the earth is not the world of cultivation. The most important thing is that the spiritual energy on the earth is too thin. No cultivator wants to stay on the earth, because cultivator is stationed on the earth. It is simply a waste of his own cultivation time.

On earth, cultivators can only rely on the spirit stones or elixirs they carry. Such practice would be fine if it was a short time, because the cost would not be large at that time. However, over time, cultivators would not be able to stand it.

Cultivators who will come to a place like the earth with thin spiritual energy must be the lowest in the cultivation sect. For such cultivators, spirit stones and elixirs are very precious things, and they don’t have many spirit stones and elixirs on them. Therefore, once these cultivators come to the earth, life is worse than death!

Correspondingly, they will attach great importance to their mana consumption.

Therefore, the demons outside the domain can walk on the earth with great confidence, because there will definitely not be many cultivators sent to the earth. Moreover, even if cultivators come to the earth, these cultivators will not go outside because they want to consume less of their magic power. Except for extremely serious matters, they will not go outside.

When things have developed here, what other concerns will these extraterritorial demons on the earth have? Therefore, these extraterritorial demons have begun to mess around on the earth.

As long as you don’t go to the places where the Wulin Secret Realm is located, and the locations of the power agencies of various countries, these extraterritorial demons can do whatever they want.

I believe everyone knows the reason why we cannot go to the place where the Wulin Secret Realm is located, and we cannot go to the place where the power agencies of various countries are located because it is very likely that this place is the stationing point of the cultivation sect on earth.

In the world of cultivation, the places where those cultivation sects are stationed in the mortal world are not the capitals of those countries. Therefore, the capitals of various countries on the earth, the demons outside the territory dare not cause trouble.

In addition to the forbidden areas in the minds of these two extraterritorial demons, other places on the earth, these extraterritorial demons can do things boldly.

Of course, some people will also ask here, aren’t these extraterritorial demons taking over the genetic warriors from Western countries? If these extraterritorial demons leave directly, Western countries will know that there is a problem with their genetic warriors. Whether it is for the sake of not leaking their genetic technology or to recover these rebellious genetic warriors, Western countries will do their best to capture these defected genetic warriors or directly eliminate them.

Once Western countries begin to launch a clearance operation against these defected genetic warriors, in the end, these extraterritorial demons will definitely cause a great shock in the world. Faced with the full-strength purge of Western countries, it is impossible for these extraterritorial demons to not use all their strength. Once the extraterritorial demons use all their strength, they will be exposed.

After the extraterritorial demons violently themselves, they did not know whether they would be destroyed by powerful weapons from Western countries, such as missiles, or other powerful weapons. However, these extraterritorial demons believed that they would definitely be targeted by cultivators in the secret realm of the martial arts world, and at that time, these extraterritorial demons were definitely dead.

Perhaps missiles and other powerful modern weapons cannot kill extraterritorial demons. The parasitic body of extraterritorial demons was destroyed by these modern weapons, but the soul of extraterritorial demons can still exist, and eventually the extraterritorial demons can still be reborn. However, once they are targeted by cultivators, the extraterritorial demons will truly fall into the realm of death.

Ordinary people cannot discover the soul, but for cultivation, the soul of the extraterrestrial demon is as bright as the lights in the darkness, and some cultivators have the means to deal with the soul of the extraterrestrial demon.

With this concern, those extraterritorial demons who seized the gene warriors dared to disappear randomly. They all thought of some ways to make themselves disappear.

Before, when warriors had not appeared on the earth in large numbers, it was impossible for extraterritorial demons to destroy their own corpses, because at that time, genetic warriors were the most powerful existence on earth, whether they were genetic warriors dead or other reasons. As long as genetic warriors disappeared, Western countries would do their best to find them.

If you die, the bodies of the genetic warriors will be taken back. Western countries will also take them back. They will prevent their genetic technology from leaking. If you don’t die, Western countries will take more care of bringing the genetic warriors back. The biggest reason is to keep their genetic technology confidential. It can be said that Western countries attach great importance to genetic warriors at that time.

However, after all this appeared, especially after the emergence of warriors, especially after several powerful attacks on Southeast Asian countries in the martial arts world, genetic warriors no longer mattered in the hearts of Western countries.

Why did Western countries abandon gene warriors so quickly and instead put all their energy on warriors? The answer is actually very simple, that is, it costs too much to create a gene warrior.

The origin of genetic warriors is genetic engineering, and genetic engineering can be said to be the most advanced technology in the world.

Genetic engineering (geicenginee) also known as gene splicing technology and DNA recombination technology, is based on molecular genetics as the theoretical basis and modern methods of molecular biology and microbiology as a means to construct hybrid DNA molecules in vitro according to a pre-designed blueprint, and then introduce them into living cells to change the original genetic characteristics of the organism, obtain new varieties, and produce new products. Genetic engineering technology provides a powerful means for the study of the structure and function of genes.

The so-called genetic engineering is a complex technology that operates genes at the molecular level. It is an operation that introduces exogenous genes into the receptor cells after being recombined in vitro, so that the gene can be replicated, transcribed, translated and expressed in the receptor cells.

Genetic engineering is an important branch of bioengineering. It together with cell engineering, enzyme engineering, protein engineering and microbial engineering. The so-called genetic engineering is a complex technology that operates genes at the molecular level.

It uses artificial methods to extract the genetic material of a certain donor organism, the DNA macromolecule, which is needed, and then cleave it with the appropriate tool enzyme under ex vivo conditions, and then connect it with the DNA molecule as the carrier, and then introduce it into a more easily grown and reproducible recipient cell with the carrier, so that the exogenous substances can "settling down" and perform normal replication and expression, thereby obtaining a new technology for new species. It overcomes the inaffinity barrier of distant hybridization.

Genetic engineering refers to the industrial design and application of recombinant DNA technology, including two major components: upstream technology and downstream technology.

Upstream technology refers to the design and construction of gene recombination, cloning and expression (i.e., recombinant DNA technology); while downstream technology involves the large-scale culture of genetically engineered bacteria or cells or genetically engineered organisms and the isolation and purification of gene products.

Genetic engineering uses recombinant technology to modify and recombinate the nucleic acids (genes) of various organisms through artificial "cutting" and "splicing" in vitro, and then introduce them into microorganisms or eukaryotic cells to express the recombinant genes in the cell, produce the gene products needed by humans, or transform them to create new biological types.

In essence, the definition of genetic engineering emphasizes that new combinations of exogenous DNA molecules are introduced into a new host organism for reproduction.

This new combination of DNA molecules is designed and operated according to an engineering method, which gives genetic engineering the ability to cross the barriers of natural species, overcomes inherent limitations between species, and expands and brings the possibility of targeted transformation of organisms. This is the biggest feature of genetic engineering.

Genetic engineering involves artificially connecting genes from different organisms with vector DNA with autonomous replication capabilities in vitro to form a new recombinant DNA. It is then sent to the receptor organism for expression, thereby producing the transfer and recombination of genetic material.

Elements of genetic engineering: including exogenous DNA, vector molecules, tool enzymes and receptor cells, etc.

A complete, production-oriented genetic engineering technology program includes basic contents: (1) isolation, cloning of exogenous target genes and research on the structure and function of target genes. This part of the work is the basis of the entire genetic engineering, so it is also called the upstream part of genetic engineering.

(2) Suitable for transfer, construction of expression vectors or recombination of the expression regulatory structure of the target gene.

(3) Introduction of exogenous genes.

(4) Integration, expression, detection and screening of transgenic organisms on the host genome.

(5) Verification of the physiological function of exogenous gene expression products.

(6) Breeding and establishment of new genetically modified products, as well as the benefit analysis of new genetically modified products.

(7) Establishment of ecological and evolutionary security guarantee mechanisms.

(8) Consumer safety evaluation.

The most prominent advantage of genetic engineering is that it breaks the boundaries of species that are difficult to break through in conventional breeding, and can recombinate and transfer genetic information between prokaryotes and eukaryotes, between animals and plants, and even between humans and other organisms. Human genes can be transferred to E. coli for expression, and bacterial genes can be transferred to plants for expression.

Genetic engineering is a brand new biotechnology science born in the 1970s based on the comprehensive development of molecular biology and molecular genetics.

This definition shows that genetic engineering has the following important characteristics: First, exogenous nucleic acid molecules reproduce in different host organisms. They can cross the barrier of natural species and place genes from any organism into new organisms, which can have no relationship with the original organism. This ability is the first important characteristic of genetic engineering.

The second feature is that a certain small DNA fragment is amplified in new host cells, so that a small number of DNA samples can "copy" a large amount of DNA, and a large population of absolutely pure DNA molecules that do not contaminate any other DNA sequences.

Scientists call the technology to change human germ cells "genomic therapy", and the commonly known as "genetic engineering" is aimed at changing germ cells from animals and plants.

Regardless of the title, changing the DNA of an individual germ cell will likely cause the same changes in its offspring.

In the early 20th century, genetic engineering was not used in the human body, but experiments were conducted on almost all non-human living objects, from bacteria to livestock, and were successful.

In fact, all insulin used to treat diabetes comes from a bacteria. The DNA is inserted into the gene that humans can produce insulin, and the bacteria can copy insulin by themselves.

Genetic engineering technology has enabled many plants to be resistant to pests and herbicides; in the United States, about half of soybeans and a quarter of corn are genetically modified.

Whether genetically modified animals and plants should be adopted in agriculture has become the focus of debate: supporters believe that genetically modified agricultural products are more likely to grow and contain more nutrients (even drugs). They help slow famines and diseases around the world; while opponents believe that introducing new genes into agricultural products will have side effects, especially environmental damage.

It is true that there are still many genes that work together and their synergistic methods are unknown to humans, but when it comes to the use of genetic engineering to make tomatoes have anti-cancer effects, making salmons grow several times larger than in nature, and making pets no longer cause allergies, many people hope to make similar modifications to human genes.

After all, technologies such as embryonic genetic disease screening, gene repair and genetic engineering can not only be used to treat diseases, but also provide the possibility to change other human characteristics such as eye color and intelligence. We are far from designing custom-made for our offspring, but there are examples of using embryonic genetic disease screening technology to cultivate physical characteristics that people need.

For example, using this technique, the child's parents can give birth to a child that matches the child's bone marrow, and then cure the child through bone marrow transplantation.

As the secrets of DNA's internal structure and genetic mechanism appear before people bit by bit, especially when people learn that the genetic code is transcribed and expressed by RNA, biologists are no longer satisfied with exploring and prompting the secrets of biological genetics. Instead, they begin to try and imagine interfering with the genetic characteristics of organisms at the molecular level.

If a certain genetic code fragment in the DNA of one organism is connected to the DNA chain of another organism and reorganize the DNA, you can design new genetic material and create new biological types according to human desires, which is completely different from the traditional practice of cultivating organisms and reproducing offspring.

This practice is like the engineering design of technology and science. The "gene" of this organism and the "gene" of that organism are re-constructed according to human needs. Biological science and technology is called "genetic engineering", or "genetic engineering". The basic operating steps are the process of in vitro recombination of DNA.

First, select the suitable carrier tools for the target gene, such as plasmids, viruses, etc., and then use the same restriction enzyme to cleave the carrier and the target gene respectively to produce the same sticky end. Then add an appropriate amount of DNA ligase, combine the DNA of the target gene with the DNA of the carrier in vitro to form a recombinant DNA (or recombinant plasmid) to form a recombinant DNA hybrid molecule, borrow the pathways of bacteria or viruses infect cells, and transfer it to the selected biological cells, so that the recombinant DNA can be replicated, transcribed, and translated in the recipient cell.

In general, the conversion success rate is only one percent when loading the target gene on a vehicle and transporting the target gene to the recipient cell through a vehicle.

For this purpose, genetic engineers have created ways to treat receptor cells with calcium chloride under low temperature conditions and increase recombinant DNA concentration to improve conversion.

After calcification of chloride, the cell wall permeability of receptor cells can be increased, thus making hybrid DNA molecules easier to enter.

In addition, gene marking method, laser microbeam perforation method, microinjection method and other methods can also be used to directly transfer the target gene into the recipient cell (such as fertilized egg cell).

The development of information technology has changed the way of life for humans, and breakthroughs in genetic engineering will help humans prolong their lifespan. The average life expectancy of the population of some countries has exceeded 80 years, and China has also exceeded 70 years.

Some scientists predict that with the effective conquering of cancer, cardiovascular and cerebrovascular diseases and other stubborn diseases, countries with an average population life expectancy of more than 100 years may appear between 2020 and 2030. By 2050, the average life expectancy of humans will reach 90 to 95 years.

Humans will challenge the limits of life sciences. One day in February 1953, British scientist Franciske-Ring-Si-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-Ri-

Interestingly, the scientist announced this major scientific discovery at a bar in Sword-Bridge.

Deciphering the genetic codes of humans and animals and plants has opened up broad prospects for conquering diseases and increasing crop yields.

In 1987, American scientists proposed the "Human Genome Project", with the goal of determining all human genetic information, determining the specific location of human genes on 23 pairs of chromosomes, identifying the order of each gene nucleotide, and establishing a human gene bank.

In 1999, the 22nd human chromosome gene code was deciphered, and the "Human Genome Project" took a successful step.

It can be predicted that in the next quarter of the century, scientists may reveal the pathogenic genes of about 5,000 genetically inherited diseases in humans, thereby finding gene therapy for fatal diseases such as cancer, diabetes, heart disease, hemophilia, etc.

The scientific community predicts that the 21st century is a century of genetic engineering.

Genetic engineering is an artificial intervention in biological genetics at the molecular level. To understand it, let’s start with bioengineering: Bioengineering, also known as biotechnology, is a comprehensive engineering technology that applies modern life science principles and information and chemical engineering, uses living cells or the enzymes produced by them to process cheap raw materials to varying degrees, and provides a large number of useful products.

The basis of bioengineering is modern life sciences, technical sciences and information sciences.

The main products of bioengineering are to provide the society with a large number of high-quality fermentation products, such as biochemical drugs, chemical raw materials, energy, biocontrol agents, and food and beverages. They can also provide humans with social services such as governance environment, metal extraction, clinical diagnosis, gene therapy and improved crop varieties.

Bioengineering mainly includes five parts: genetic engineering, cell engineering, enzyme engineering, protein engineering and microbial engineering. Among them, genetic engineering is to transform biological genes and use organisms to produce special products that people want.

Gilbert of the United States is the founder of base arrangement analysis. He took the lead in supporting human genomic engineering. If a certain genetic code fragment in a biological DNA is connected to the DNA chain of another biological. Reorganize the DNA, can we design new genetic material and create new biological types according to human wishes?
