A human cell contains 46 DNA molecules, which are more than 2 meters long when straightened and connected end to end.

There are 60 trillion cells in an adult's body, and if all the DNA in these 60 trillion cells is connected into a line, the total length is 120 billion kilometers, which is 800 times the distance from the earth to the sun at 150 million kilometers.

With such a long DNA line, who can guarantee that no link will go wrong?

Human beings are small and at the same time grand.

Science is cruel and at the same time benevolent.

Han Meng agreed with Shen Qi's calculation conclusion, he knew that he would inevitably die, sooner or later.

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

In the face of death, Han Meng saw it clearly, and he said: "But a moment of life is also life." While I am still alive, I will sacrifice my life to science and become a sacrifice of science. If our research fund is sufficient, can I apply to modify my disease-causing gene?"

Shen Qi shook his head: "More than 5 million of the 11 million funds in the first research stage of our research group have been spent, and the remaining money is obviously not enough to support genetic modification of you." Han Meng, you also know, the precise editing and modification of genes is extremely expensive. And modifying all of your disease-causing genes into healthy genes is calculated to be 57.8%, which means that more than half of your genes need to be modified. We have more than 5 million dollars left, and we can't even afford a microrobot. ”

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

"Controlled, scientifically valuable editing of human genes is not in our first phase of research, but it will be implemented in later phases. Shen Qi said.

"Roger, understood. ”

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

"This is also true, Director Shen must not be allowed to take the slightest risk. Han Meng thought about it, and then dismissed the idea of modifying the gene.

Shen Qi continued: "Unless you sign a life and death certificate, voluntarily bear all the consequences, or even die in the line of duty." ”

"I signed. Han Meng didn't hesitate for a second, his father left, his mother left earlier, he had no brothers and sisters, no spouse, no children, his mentor was taken away, I don't know what year and month he would see the light of day again...... All in all, Han Meng, who was alone, had no worries.

Even if you don't have any concerns, it's not like you can do it right away if you want to do a genetic modification with a coverage rate of 57.8%.

First you have to be rich.

And then the institution that you pay for, has more mature technology to perform genetic modifications on you.

Angelina Jolie, the goddess in the hearts of many otaku, said in her breast-cutting statement: "My mother battled cancer for almost 10 years and she died at the age of 56...... I've always told my kids not to worry, but in fact, I carry that faulty gene, BRCA1, which greatly increases my risk of breast and ovarian cancer...... My doctors predicted that my risk of breast cancer was 87% and that of ovarian cancer was 50%...... As soon as I realized that this was the reality I was facing, I immediately decided to take action to minimize my risk of getting sick. I took action and underwent a prophylactic breast totomy. ”

Angelina Jolie's breast totomy was done in April 2013, she believes in science, she believes in genetics, and she is also wealthy.

But she only had a prophylactic breast tomy instead of having her doctor modify her BRCA1 gene.

Genetic modification is not enough to believe in science.

It is also necessary to love science, and have the determination and courage to dedicate oneself to science.

And to be rich, to be very rich.

Han Meng has worked in the laboratory all his life, and when he retires, he may be able to save enough money for genetic modification.

Shen Qi continued to ask: "Han Meng, once the funds are in place...... I think that day will come sooner or later. Suppose that when the day comes, we are in a position to make a genetic modification with a coverage of 57.8% on you, and the modification is successful, and you don't hang up directly, and you don't trigger a new mutation. 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, you have become a completely new person biologically, and if you have offspring in the future, you will be the ancestor of your bloodline. This also means that you will be disconnected from your biological parents. Can you accept such an outcome?"

"For the sake of science, I choose to accept. "Han Meng is a determined and loyal scientist who has repeatedly emphasized that he is willing to pay any price, even to death, to the genetic material of his ancestors, for the sake of his love of science.

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

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

The four of them are not perverted enough, they don't make public their genetic sequencing results, they say they need a little time to think about it.

Including Han Meng, five doctoral students were extremely interested in Shen Qi's gene sequencing results. Shen Qi is such a powerful boss, he has solved so many world problems and made so many top scientific research results, what are his genes? Is it close to perfection?

"Confidentiality for the time being. Shen Qi smiled, leaving a suspense.

A few days later, Shen Qi told Han Meng, Cui Hualin, Du Yuan, Tang Yaxing, and Wu Junqiang: "I pulled a sponsorship outside, and the newly arrived scientific research funds are enough for the six of us, each of whom will do one-stop full-service gene editing, are you interested in experiencing it?"

"Such a large sum of money, so quickly?" The five doctoral students were very surprised by Shen Qi's ability to make money. Six people, each doing a full set of gene editing, would require a nine-figure budget, right?

This big money was not given by the state, Shen Qi said, this fund was sponsored by him outside.

Han Meng, Cui Hualin, Du Yuan, Tang Yaxing, and Wu Junqiang didn't know anything, and they didn't dare to ask anything.

Anyway, it's OK when the funds are in place, and you can carry out follow-up scientific experiments.

Cui Hualin, Du Yuan, Tang Yaxing, and Wu Junqiang thought about it for a few days, but they still did not reach the realm of perversion. It takes some time to adjust your mindset.

Shen Qi also did not disclose his genetic sequencing results.

Therefore, everyone expects that the genetic modification experiment will be the first to be operated on Han Meng.
