After tireless exploration, scientists in this world have come up with many ways to obtain the target gene.

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

   The most commonly used method for direct gene isolation 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 cell into many fragments, load these fragments into a carrier, and then transfer the carrier to different recipient cells, so that the donor cell provides All fragments of DNA (that is, foreign DNA) are replicated in large quantities in each recipient cell, and the cells containing the target gene are found out, and then the DNA fragments with the target gene are separated by a certain method.

  Many insect and virus resistance 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 it has a large workload and a certain degree of blindness.

   There are two more ways to artificially synthesize genes.

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

Another way is to infer the corresponding messenger RNA sequence based on the known amino acid sequence of the protein, and then infer the nucleotide sequence of its gene according to the principle of base complementary pairing, and then chemically use single nucleoside 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 extraction methods are all expressed dominant genes, and recessive genes have no external manifestations, so they cannot be screened out.

   In addition, this kind of workload is large and does not require too much technical content of the experiment. For Lin Huai, who has to study more than 1,000 copies at present, and will study more in the future.

   is a waste of time!

  It would be nice to say that if someone is assisted, it can share the workload.

   But the cautious Lin Huai did not want to reveal a little bit of his experimental process before he found a very reliable way to control people.

   But since Lin Huai is standing here preparing to do experiments, naturally there is a corresponding solution.

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

   Lin Huai felt very lucky.

   Interstellar World has a basic genetic testing technology that can easily solve the above-mentioned problems.

   This kind of technology can accurately locate the position and trajectory of each atom through the computing power of the speed of light of artificial intelligence, and use big data for statistics, and finally the general ability of the gene can be obtained.

   The whole process is difficult to say, and simple is not that simple.

   For ordinary people to come to this world, it is difficult to get things like artificial intelligence alone. Although supercomputers are fast in computing, they are not intelligent enough to use them directly.

   And even if the position and trajectory of the atom are measured by you, there is no database for comparison.

   The Human Genome Project before the world's resurrection.

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

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

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

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

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

   It can be said that if Lin Huai does not exist after crossing through, the database in his mind can also make him feel good in this world.

   I want to ask Lin Huai why he still remembers this thing because...when he was studying in a higher education institution.

   This database needs to be memorized!

   is to recite! !

   You can't graduate without memorizing it! ! !

   Ghost knows what the students at the time scolded the person who set this task.

   It can be said that at that time, the students of the genetic direction picked up the book to recite, and put down the book to scold their mother.

   Lin Huai at the time didn't understand why there was such an academic task. It was obvious that everyone had a portable brain, so just check if you don't.

   If it weren't for genetic medicine that has a great effect on the brain, most people can't remember it at all.

   But he understood after graduation.

  Because after memorizing the entire database, genetic research is really easier in the future.

   This is like clearly that everyone now has a mobile phone, and 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 head is the basic mastering of a major.

   Now Lin Huai somewhat wants to kneel down to thank the teacher who forced them to endorse at the beginning.

  He is also very grateful for his own efforts at the beginning. For safety reasons, the chip will not be attached with any data before being loaded into the brain.

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

   Actually, if there is no No.1~www.wuxiahere.com~ Lin Huai really can't perform this experiment in a short time.

  Because he can't even afford the transmission electron microscope, which is the easiest to get in the whole process, the cheapest transmission electron microscope is about one or two million. This is still a small, low-voltage microscope that does not meet Lin Huai's expectations.

   Fortunately, the scanning device of No. 1 is also very accurate. It was originally a chip made for Lin Huai.

   In order to be safe, he watched the entire assembly process, and he asked grandpa to tell grandma to replace the installation colleagues with the top-notch equipment.

   How embarrassed I was when I was asking for help, but now I can operate it more easily.

  ......

   At the same time, Jiangbei Province Budo University

   A handsome young man dressed in white casually glanced at the latest news from the school mission office, tapped his finger, and said, "The Rat King in the suburbs, interesting. I'll take this mission."

The teacher in charge of task management was surprised when he saw the task he chose, and immediately persuaded: "Shen, this rat king is strong, and the key is to have a certain mentality. He leads many rats and grandchildren to hide in the wilderness in the suburbs. In the ridge, if it were not for bad luck and being discovered by the strong, waiting for him to develop would definitely be a big deal.

   Even though it has been injured by the strong, more than half of its beasts have died, but the dead camel is bigger than a horse, so it is not something ordinary students can deal with. "

   Shen Cangyang nodded in agreement: "Thank you for the teacher's concern. You are right. The average student cannot deal with this rat king, but I am not the average student you mentioned.

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

   I just broke through the realm of martial arts today, and I was looking for something to practice my hand. This Rat King is really just right.
