In the face of Nana's flattering and pleading gaze, the elder relented again, and 10 minutes later, Maya directly left Nana to spend the night at her house.

Lying in bed at night, Maya also asked about Nana's situation.

The high school next to President Maya's elementary school has a very poor teaching quality, of course, the poor academic performance can't only be blamed for the poor school, smart children don't have to go to school, and they can be admitted to a good university by studying at home, but Nana is obviously not one of those self-taught children. Actually, this is also a little ill-conceived by President Maya, when she was in elementary school, Nana has always had her help tutoring, plus there is less schoolwork in primary school, and there is little pressure to study, Nana can barely keep up with the progress of school learning.

In high school, Nana's "pillar of the nation", President Maya, transferred to another school and left, and she became a bit of a Muggle. It's not that Nana can't ask others, but even if other "excellent" students can't compare to Maya?

Maya didn't think it through, she just ignored Nana's part-time job after school, and she couldn't find time to make up for her classes.

President Maya is a part-time job for the purpose of experiencing life and earning some pocket money by the way, after all, her grades have been very good since she was a child, not only is the tuition free but also can get various scholarships, Jennifer and Jack can barely support themselves, so although her family is poor, she is never short of money... Well, the lack of money here means that there is no shortage of money for food and clothing.

Nana is different, she works to support her family, of course, Nana's family is not short of money, well, after she works to subsidize the family, it is basically the same as Maya's original living standard, otherwise Maya doesn't mind supporting her friends.

Just because she has to work part-time, she can't spare time to make up classes during the day, and Maya directly sends money and it hurts her feelings too much, so Maya prepared the above four teaching books for Nana. That's what she tailors according to Nana's habits, eight years of getting along, what kind of realm Nana is, she really knows it clearly.

Preparing a birthday present for Nana, and the chakra was consumed, President Maya didn't want to sleep, so she came to her lab alone.

Releasing her senses, sensing that the cells in the dish had stopped dividing, Maya changed into a sterile gown and began to prepare for the experiment.

The mammary gland cells in the petri dish were taken from the pig mother Helen, as early as yesterday afternoon, Maya put into a low-concentration nutrient culture medium, and the nutrients could only maintain the survival of the cells, so the cell division stopped.

This process of making donor cells is difficult to say and easy to say, the difficulty is that Maya is not experienced enough for the first time, and it is easy for Maya to perceive, and she can know whether the cells have stopped dividing without a microscope at all. In the same way, this culture medium is also specially configured by herself, because she can sense the activity of organelles, and her culture medium is much stronger than that of other laboratories.

Recipient cells, that is, enucleated egg cells, have also been prepared for a long time, and there is nothing to say about this, I don't know how many times Mayan stem cells have been cloned before.

Next is the most important problem, and the one that Maya has to overcome now, is to fuse cells!

At this time, Maya had two options, one was to follow the old path of Dolly the sheep and fuse the donor cells with the recipient cells through the electrical pulse method, and the second was to continue to take out the nucleus of the donor cell and put it into the recipient egg cell as she had done with her previous stem cell cloning.

The first way is completely innovative for her, and she has taken an unknown path, but the future is bright, and with the example of Dolly Sheep in the past, she can always experiment with her own path.

Second, she is very familiar with it, but the future is unknown, somatic cells are different from stem cells, stem cells are totipotent cells, after nuclear transfer, egg cells can still develop into embryos, and after somatic cell nuclear transfer, maybe just cell division, develop into a polyp.

It is all cell division, and totipotent cells can develop into complete living individuals, and somatic cells are still somatic cells after division, which is why somatic cell cloning is so difficult.

What are the benefits of the electrical impulse method?

The electrical impulses are able to produce a series of reactions similar to those in the natural fertilization process, so that the fused cells can also divide and differentiate like a fertilized egg, thus forming "embryonic cells".

Which one did Maya choose?

The answer is both!

If she is simply cloning a piglet with somatic cells, then she will naturally follow the old path of Dolly sheep, although she has to explore step by step, but Maya will definitely be able to succeed with her own plug-in.

But Maya not only wants to succeed, she is more ambitious, she wants to be more sensational, more successful, she wants to make a super big news, she wants to let the scientists in the biological gene research circle on the whole earth know that Maya Hansen is a bull breaking guy.

Why?

Even the guys who completed the cloning of Dolly sheep on the original earth failed to win the Nobel Prize, for other reasons, such as whether someone deceived the world and so on, but the appearance of Dolly sheep has a great chance factor is everyone's consensus.

Maya's somatic cell cloning was originally to become famous, to be on top, to let everyone recognize her, so that she could get an invitation to the black technology laboratory in the Marvel world.

That's the treatment of the original Earth Dolly sheep, how terrible is Marvel Earth, can President Maya not count b? For example, the Parkers who are engaged in gene grafting, to be honest, Maya herself understands that the Parker couple's experimental project is 10,000 times more difficult than somatic cell cloning, yes, you read that right, it is 10,000 times!

It's 2018, one day you suddenly saw from Baidu that a lab had defied the world's condemnation and made a clone, and you probably would only mumble "Ma Dan, finally exposed". But if "from today onwards, the people of a certain country are Spider-Man" appears on Baidu's hot search list, anyone who sees it will scold "Xiaobian is a sand sculpture".

In the final analysis, somatic cell cloning is not genetic engineering, and it is more than thousands of miles away from genetic modification!

Of course, this doesn't mean that Maya is 10,000 times worse than the Parkers, whose project is 10,000 times more difficult than Maya's somatic cell cloning, but will the Parkers be able to fully achieve the intended goals of the experimental project? The answer is clearly no.

A certain street writer found that the great god subscribed hundreds of times more than himself, and a chapter updated by others was worth half of his book, so he thought, "The great god doesn't need to think about it, it's terrible." The little god code 2k words a day, I code 200,000 words, hey, hey, hey, so I earn more than him, and I can be regarded as a small god", so he set himself a goal of 200,000 per day.

Well, it's the same as the Parkers, they are ambitious, but almost unachievable.

Ahem, cough cough, after so much, I just want to say that just completing somatic cell cloning is not brilliant enough, Maya wants more, so she thinks about completing genetic adjustment at the same time as somatic cell cloning.

And her target is Lona's vote - Marcos!

Sampling from Marcos was very simple, and she found the DNA fragment that absorbed the light and released it through the green merger. Direct DNA grafting is completely impossible, and that's what the Parkers do.

However, in order for DNA to express its own recorded information, it must be realized through RNA, and after DNA transcribes the information to RNA, RNA enters the cytoplasm, absorbs nutrients, and synthesizes functional protein macromolecules, which are superpower carriers.

Maya can't "edit" the DNA chain — and neither can the Parkers, but Maya has a trick that other genetic engineering researchers would be the envy of other genetic engineering researchers, and that's that she can sense RNA in the cytoplasm.

President Maya's idea was to take out the RNA that recorded Marcos's superpowers and stuff it into the nucleus of the egg cell, anyway, there is cytoplasm and free RNA in the egg cell, and it doesn't matter if you have more of this RNA. An electric pulse is then used to fuse the egg cells with the target RNA and the donor cells.

If the fused cells can develop into embryos, then the piglets born from the embryos will have a copycat version of the x ability.

Of course, these are Mayan ideas, and the real process must be extremely difficult, with rejection and survival rates of the target RNA predictably difficult.

However, in this perverted Marvel Earth, if you don't work hard, if you don't fight, how can you surpass others?

Don't you see, has President Maya started to burst his liver?

Alas, it's a pity that there is still information asymmetry, and the self-motivated President Maya doesn't know that the president of the United States has begun to care about the future of the "motherland", and all those who show amazing talents are the targets that have been marked! 166 Reading Network
