Chapter 106 Gene Recombination Technology

"OK, that's fine."

Chi Heng took off the biological protective clothing neatly. Maybe the researchers who used to work here have this system requirement, just like safety production requires helmets, even construction sites that have stopped construction need helmets.But everything can't be absolute, and the harm between the two powers is the lesser. He doesn't want to affect his actions because of wearing protective clothing, so that he can't even dodge when there is an accident like before.

One is a known accident, and the other is a biological hazard that may occur with a very small probability. Chi Heng did not hesitate.

"The next step is to sample our 'uninvited guest'."

"But it can't appreciate my kindness, so what if it doesn't take sleeping pills?"

Chi Heng frowned, "We can only forcibly use tranquilizers on it."

I don't know if there are sedatives in the biological laboratory, but it seems that there are not, but there are a lot of medicines in the previous medical treatment center, and there must be sedatives.

Chi Heng and "Broken Copper and Iron" returned the same way first, went to the medical treatment center to get the barbiturates, and used the printed box to put the "old man" into it, and brought it into the core area.

Having not seen Chi Heng for several hours, the "old man" was very wronged, and he never left Chi Heng even when he came to the core area, for fear that the owner would drop him again.

It wasn't until he saw the "hedgehog and leopard" that the "old man" barked in fright.

On the contrary, "Hedgehog and Leopard" calmed down from grinning, and stared at the "old man" quietly, as if very curious about what kind of animal it was.

"Try a small dose first to see if there are any adverse reactions."

Chi Heng instructed.

After all, sedatives are relatively dangerous drugs, and one of the adverse reactions is respiratory depression. Chi Heng felt that this "hedgehog leopard" was extremely cherished, and he didn't want to kill it just like that.

"Battered copper and iron" was about to inject tranquilizers into "Hedgehog Leopard", and seemed to realize something. "Hedgehog Leopard" was struggling hard, but unfortunately its neck was stuck, no matter how hard it struggled, it was useless, and it was still injected with sedation agent.

Small doses of sedatives will make the user turn from excitement, agitation, and restlessness to quietness, mainly through the GABAA macromolecular complex to trigger the conformational change of the receptor protein, so that the frequency of opening the chloride ion channel increases, so that there are more chloride ions in the body. The flow strengthens the inhibitory effect of GABA on the nervous system.

The GABAA receptor is ubiquitous in mammals, rodents, and even fruit flies.

So although the "hedgehog and leopard" in front of me doesn't look like a natural animal, there is a high probability of this kind of receptor...

Sure enough, after a while, the manic "Hedgehog Leopard" began to calm down, as if all the sources of its anger had disappeared.

"It really works."

Chi Heng nodded, "Let's draw blood for it first."

Several tubes of blood samples were drawn in a row, and then, under Chi Heng's order, "Broken Iron" injected a large dose of tranquilizer into "Hedgehog Leopard", and now "Hedgehog Leopard" couldn't hold on anymore, and the effect of the medicine increased Soon after, he fell asleep.

After confirming that "Hedgehog Leopard" has entered a deep sleep, "Broken Iron" put it down and took it to the second P1 laboratory for CT scanning. In addition, the most important thing is to test blood samples and DNA analysis.

Chi Heng knew nothing about biology, but the "bad metal" memory chip stored a lot of biological knowledge. While testing the "hedgehog leopard" gene, he explained his doubts to Chi Heng.

Prior to this, Chi Heng felt that although this "hedgehog and leopard" seems weird, its genes should not be much different from humans. It doesn't mean that the genetic difference between chimpanzees and humans is only about 1.2%, and even bananas and humans have 60% of the same genes ?
"Broken copper and iron" denies this statement.

In fact, the genes of organisms are not as simple and clean as they appear in the double helix diagram. If you want to compare them, genes are more like a word library in a Word document.

The similarity of biological genes is more like sharing a set of similar fonts.

For example, the genes of chimpanzees and humans are roughly the same, which refers to the similarity of this set of fonts, not the similarity in gene function.

But this set of "character library" is a collection of gene stocks accumulated by humans and many organisms from ancient microbial ancestors. According to the evolution of different organisms, there are different degrees of sharing. More than 90% of the genes are just reserves, and only 10% This is where most of the activation energy is used.

Among these 10% genes, the key to affecting organisms is not the gene pool, nor the arrangement order, but when these genes in the gene pool are called, how they are called, where they are called, and so on.

Just like writing an article with a Word document, the key to an article is not the word library, but the words formed by the words, the sentences formed by the words, and how and where the sentences appear, thus forming various articles that are ever-changing.

Although these articles use the same text, the content is completely different.

It is said that gorillas and human beings are so genetically similar, which describes the similarity of the word library, but Chi Heng and many people understand it as the similarity of the content of the "article", which is fundamentally different. All wrong.

The beginning of human research on genes is gene sequencing, which is to find out all the characters in the "character library". After finding out the "character library", can it be said that we can understand the thought and meaning of a book?
It is equivalent to a child who has just learned to recognize characters. If he can recognize every word in the world's famous books, can he understand the thoughts and expressions of the world's famous books?
so far...

The research of human beings' own genes is still pondering the meaning of the combination between "words" and "words", and they have not fully understood, let alone these "words" behind them, which form sentences in unique ways to form special Functions, special functions are combined into a great "book", and the "author" who created "this book", that is, the idea of ​​"author" revision has evolved.

Therefore, if the "Hedgehog Leopard" is handed over to the humans in Chi Heng's world, they may not be able to figure out more useful clues, at least it will take a lot of time to gain something.But here, in just over an hour, "broken copper and iron" produced a preliminary test report.

"The part that regulates gene expression is almost highly similar to that of humans, but the regulation gene expression of cats is inserted in the middle..."

"Broken copper and iron" made a report to Chi Heng and explained why the distance between the two exons on a certain chromosome is abnormal. Humans should be 6.7 bp, but the two exons corresponding to "hedgehog and leopard" are not. It is 2.5 bp.

Chi Heng became dizzy after hearing this, and interrupted the words of "Broken Copper and Iron", "That is to say, this is some kind of genetic recombination technology? A hybrid of human and animal genes?"

The tone of "broken copper and iron" remains unchanged: "The regulatory mechanism of genes is very complicated. Judging from the current evidence, it does have traces of some kind of genetic recombination technology."
