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 the gene from the DNA of the donor cell; the other is to artificially synthesize the gene.

The most commonly used method for direct isolation of genes is the "shotgun method", also known as the "shotgun method".

The specific method of the shotgun method is: use restriction enzymes to cut the DNA in the donor cell into many fragments, load these fragments into the carrier respectively, and then transfer them into different recipient cells through the carrier, so that the DNA provided by the donor cell All fragments of DNA (that is, foreign DNA) are copied in large quantities in each recipient cell, and the cells containing the target gene are found, and then the DNA fragments with the target gene are separated by a certain method.

Many anti-insect and anti-virus genes are obtained by the above methods.

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.

And there are two methods of 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 chemically convert Acid is used as raw material to synthesize the target gene.

The method is very good, but there are a few 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 a thousand 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, didn't want to reveal a little bit of his experiment process until he found a very reliable method of controlling 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, and it is a summary of the genetic level of the entire interstellar world.

Putting human genes in it is like a drop of water falling into the sea, and there is no splash at all.

The database contains comparisons of numerous atom 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 there is no No. 1 after Lin Huai crosses,

Just relying on this database in his mind can make him thrive in this world.

I have to ask Lin Huai why he still remembers this incident, 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 really 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.

Keeping all the professional things in your mind is the basic mastery of a major.

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

He is also very grateful for his efforts at the beginning, knowing that for safety reasons, the chip will not be accompanied by any information before it is loaded into the brain.

No. 1's current analysis is based on his memory. If Lin Huai can't, No. 1 will be blind.

In fact, without the existence of No. 1, Lin Huai really couldn't carry out this experiment in a short time.

Because he couldn't even afford the easiest transmission electron microscope in the whole process. The cheapest transmission electron microscope was around one or two million yuan. This was a small, low-voltage microscope that didn't meet Lin Huai's expectations.

Fortunately, No. 1'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, how fun it is to operate 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, "The mouse king in the suburbs, interesting, I've accepted this mission."

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