Chapter 31 Gene Databases

Scientists in this world have unremittingly explored and come up with many ways to obtain the target gene.

There are two main ways: one is to directly isolate genes from the DNA of donor cells; the other is to artificially synthesize genes.

The most commonly used method for directly isolating genes is the "shotgun method", also known as the "shotgun method".

The specific method of the shotgun method is to use restriction enzymes to cut the DNA in the donor cells into many fragments, load these fragments into carriers, and then transfer them into different recipient cells through the carriers, so that the donor cells can provide All fragments of DNA (that is, foreign DNA) are replicated in large quantities in each recipient cell, and cells containing the target gene are found, and then the DNA fragments containing the target gene are isolated using a certain method.

Many insect-resistant and anti-viral genes are obtained using the above method.

The advantage of using the shotgun method to obtain the target gene is that it is easy to operate, but the disadvantage is that the workload is large and it has a certain degree of blindness.

There are two methods for artificially synthesizing genes.

One way is to use the messenger RNA transcribed from the target gene as a template, reverse transcribe it into complementary single-stranded DNA, and then synthesize double-stranded DNA under the action of enzymes to obtain the desired gene.

Another approach is to deduce the corresponding messenger RNA sequence based on the known amino acid sequence of the protein, and then deduce the nucleotide sequence of its gene according to the principle of complementary base pairing, and then use chemical methods to synthesize Acid is used as raw material to synthesize the target gene.

The method is very good, but there are several problems that Lin Huai needs to solve.

First, the above-mentioned extraction methods only obtain expressed dominant genes, and recessive genes do not have any external manifestations, so they cannot be screened out.

In addition, this kind of experiment requires a lot of work and does not require too much technical content. For Lin Huai, who currently has to study more than 1000 copies, and will study more in the future.

What a waste of time!
If someone assists, it's okay to say that the workload can be shared.

But Lin Huai, who was cautious, did not want to reveal any of his experimental process until he found a very reliable way to control people.

However, since Lin Huai is standing here and preparing to conduct experiments, he naturally has a corresponding solution.

"Fortunately, I brought number one here, otherwise there is really no good way now."

Lin Huai was very happy.

There is a basic genetic testing technology in the interstellar world that can easily solve the above problems.

This technology can accurately locate the position and trajectory of each atom through the calculation ability of the speed of light of artificial intelligence, and use big data to make statistics, and finally get the general ability of the gene.

The whole process is not difficult to say, but it is not so simple to say simple.

For ordinary people to come to this world, it is difficult to obtain such things as artificial intelligence alone. Although supercomputers are fast in calculation speed, they are not intelligent enough to be used directly.

And even if the positions and trajectories of the atoms are measured by you, so what, it is useless without a database for comparison.

The Human Genome Project before the World Resurrection.

The purpose is to explore all the genetic information of human beings, determine the specific positions of human genes on the 23 pairs of chromosomes, find out the nucleotide sequence of each gene, and establish a human gene bank.

Of course, the interstellar world has a similar genetic database, which is countless times larger than the Human Genome Project. It is a summary of the content of the entire interstellar world exploring the genetic level.

Putting human genes in it is like a drop of water falling into the ocean, unable to make any splash at all.

The database contains comparisons of numerous atomic positions and gene functions.

These results are not due to strong winds. Behind each conclusion is the discussion and research of countless researchers day and night.

It can be said that if Lin Huai did not have No. [-] after crossing, the database in his mind alone would allow him to thrive in this world.

I have to ask Lin Huai why he still remembers this matter, because... when he was studying in an institution of higher learning.

This database needs to be memorized!
I have to recite it! !

You can't graduate if you don't memorize it! ! !

The ghost knows how the students at that time scolded the person who set up this task.

It can be said that the students of the gene direction at that time picked up the books to recite, and put down the books to scold their mothers.

At that time, Lin Huai didn't understand why there was such an academic task. Obviously, everyone has a portable brain, so just check it out if you don't know it.

If it weren't for the fact that the genetic medicine also has a great effect on improving the brain, ordinary people would not be able to memorize it at all.

But after graduation he understood.

Because after memorizing the entire database, it will be much easier to do genetic research in the future.

This is like everyone who has a mobile phone now, but those who study medicine still have to memorize a lot of treatment manuals, and those who study law still have to memorize a lot of legal provisions.

Only by memorizing all professional things in your mind can you basically master a major.

Now Lin Huai almost wanted to kneel down and thank the teacher who had forced them to endorse him behind his back.

He was also very grateful for his original efforts. For safety reasons, the chip would not be accompanied by any data before being loaded into the brain.

Number One's current analysis is all based on his memory. If Lin Huai didn't know how to do it, Number One would be blind.

In fact, without the existence of No. [-], Lin Huai really couldn't carry out this experiment in a short time.

Because he couldn't even afford the most easily available transmission electron microscope in the whole process. The cheapest transmission electron microscope was around 200 million. This was a small, low-voltage microscope that did not meet Lin Huai's expectations.

Fortunately, No. [-]'s scanning device is also very accurate. It was originally a chip made for Lin Huai himself.

To be on the safe side, he watched the entire assembly process, and begged his grandpa to tell his grandma to replace all the supporting equipment with top-notch ones.

How embarrassing it was when asking for help at the time, but how smooth it is now.

At the same time, Wudao University of Jiangbei Province
A young man dressed in white with a handsome face casually glanced at the latest news from the school's mission office, tapped his finger lightly, and said, "Shu Wang in the suburbs, interesting, I've accepted this mission."

The teacher in charge of task management was surprised when he saw the task he had chosen, and immediately persuaded him: "Student Shen, this mouse king is very powerful, and the key is his mentality. Among the mountains, if it wasn't for bad luck to be discovered by a strong man, it would definitely be a big problem for him to develop.

Although it was wounded by the strong and more than half of its beasts died, the emaciated camel was bigger than a horse, so it was still not something ordinary students could deal with. "

Shen Cangyang nodded in agreement: "Thank you teacher for your concern, you are right, ordinary students really can't deal with this mouse king, but I am not the ordinary student you said.

Don't worry, since I dare to accept this task, I must have the strength to complete it. "

Today I just broke through the realm of a martial artist, and I was looking for something to practice my hands with. This mouse king came just right.
