I Just Want to Be a Quiet Top Student

A human cell contains 46 DNA molecules, and if they are straightened end to end, the length is more than 2 meters.

There are 60 trillion cells in an adult human body. If all the DNA in these 60 trillion cells is connected into a line, the total length will reach 120 billion kilometers, which is 800 times the distance from the earth to the sun of 150 million kilometers.

With such a long DNA circuit, who can guarantee that there is no error in any link?

Human beings are small and at the same time huge.

Science is cruel and kind at the same time.

Han Meng agrees with Shen Qi's calculation conclusion, he knows that he will inevitably die, sooner or later.

"I don't want to die, but I'm not afraid of death. I have to die if necessary."

Facing death, Han Meng saw it clearly, and he said again: "But a moment of life is also life. When I am still alive, I am willing to dedicate myself to science and become a sacrifice of science. If the scientific research funds of our research group Enough, can I apply to modify my disease-causing gene?"

Shen Qi shook his head: "Our research team has already spent more than 5 million of the 11 million yuan in the first research phase, and the remaining money is obviously not enough to support your genetic modification. Han Meng, you also understand that genetic modification Precise editing and modification are extremely expensive. To modify all your disease-causing genes into healthy genes, the coverage rate is calculated to be 57.8%, that is to say, more than half of your genes need to be modified. We have more than 5 million funds left , can’t even afford a tiny robot.”

"Yes, I understand." Han Meng nodded and said, "I'm just asking, after all, modifying my genes is not within the scope of our research."

"Controllable and scientifically valuable editing of human genes is not in our first research stage, but will be implemented in later research stages." Shen Qi said.

"Got it, understand."

Shen Qi asked again: "Han Meng, are you really willing to modify your genes? Technically speaking, if the funds are in place, we can do it. But you have to think clearly, even if I make the plan and implement it operation, it may still lead to unpredictable mutations in your modified genes, and even cause you to die directly. If you die in our laboratory, I, Shen Qi, cannot bear the responsibility. You also know that I have I am old, I am young, I will be a father again in a few months..."

"That's true, Director Shen must not be allowed to take the slightest risk." Han Meng thought for a while, and then gave up the idea of ​​​​modifying the gene.

Shen Qi went on to say: "Unless you sign the life and death certificate and voluntarily bear all the consequences, or even die in the line of duty."

"I'll sign." Han Meng didn't hesitate for a second. His father left, and his mother left earlier. He has no brothers, sisters, spouse, or children. His mentor was taken away. I don't know when Only the moon can see the sun again... All in all, Han Meng, who is alone, has nothing to worry about.

Even if you have nothing to worry about, it is not something you can do immediately if you want to do genetic modification with a coverage rate of 57.8%.

First you have to be rich.

Then the institution you pay for has relatively mature technology to carry out genetic modification on you.

Angelina Jolie, the goddess in many otaku's minds, said in her breast cutting statement: "My mother fought cancer for nearly 10 years, and she died at the age of 56... I have always let the children Don't worry, but the truth is, I carry that faulty gene, BRCA1, and it dramatically increases my risk of breast and ovarian cancer...my doctors predict my risk of breast cancer to be 87% with a 50% risk of ovarian cancer...Once I realized that this was the reality I was facing, I decided to act aggressively to reduce my risk as much as possible. I took action and received preventive mastectomy."

Angelina Jolie, whose mastectomy was completed in April 2013, believes in science, believes in genetics, and is wealthy.

But she only had a preventive mastectomy instead of asking her doctors to modify her BRCA1 gene.

For the operation of genetic modification, it is not enough to believe in science.

More importantly, we must love science and have the determination and courage to dedicate ourselves to science.

And you have to be rich, you have to be very rich.

Han Meng worked in the laboratory all his life, and by the time he retired, he might be able to save enough money for genetic modification.

Shen Qi continued to ask: "Han Meng, once the funds are in place... I think this day will come sooner or later. Suppose that when this day comes, we have the conditions to modify your genes with a coverage rate of 57.8%, and the modification is successful. You Did not die directly, and did not cause new mutations. So, what I want to say is that Han Meng is no longer the same Han Meng as before. More than half of your genes have been modified, and you have become a completely new biologically. People, if you have descendants in the future, you will be the ancestors of your blood. This also means that you will sever your blood relationship with your biological parents. Can you accept such a result?"

"For the sake of science, I choose to accept it." Han Meng is a firm and loyal science warrior. He repeatedly emphasized that for the science he loves, he is willing to pay any price, even death, and even abandon the genetic material of his ancestors.

"Han Meng, he is really a strong general." Shen Qi couldn't help feeling, he knew it in his heart.

Shen Qi turned to ask Cui Hualin, Du Yuan, Tang Yaxing, Wu Junqiang and other four people: "Han Meng has expressed his opinion, what about you?"

The four of them are not perverted enough, they did not disclose their genetic sequencing results, they said they need a little time to think about it.

Including Han Meng, the five doctoral candidates were extremely interested in Shen Qi's gene sequencing results. Shen Qi is such an awesome boss, he has solved so many problems in the world, and made so many top scientific research achievements, what is his gene like? Is it close to perfect?

"Temporary secrecy." Shen Qi chuckled, leaving some suspense.

A few days later, Shen Qi told Han Meng, Cui Hualin, Du Yuan, Tang Yaxing, and Wu Junqiang: "I made a sponsorship from outside, and the new scientific research funding is enough for six of us, and each of us can do a one-stop full-service Are you interested in experiencing gene editing?"

"Such a large amount of money has arrived so quickly?" The five doctoral students were very surprised by Shen Qi's ability to spend money. Six people, each doing a full set of gene editing, the required funding must be nine figures, right?

This large sum of money was not given by the state. Shen Qi said that this fund was a sponsorship he solicited from outside.

Han Meng, Cui Hualin, Du Yuan, Tang Yaxing, and Wu Junqiang knew nothing and dared not ask.

Anyway, if the funds are in place, it will be OK, and follow-up scientific experiments can be carried out.

Cui Hualin, Du Yuan, Tang Yaxing, and Wu Junqiang thought about it for a few days, but they still haven't reached the state of abnormality. It takes some time to adjust the mentality.

Shen Qi also did not disclose the results of his gene sequencing.

Therefore, as expected, the genetic modification experiment will be carried out on Han Meng first.
