"Hahaha, okay, attack the shield of the son with the spear of the son, Qin Ran, your speech this morning is simply very pleasant!"

During the lunch break, Jiang Weiguo and Qin Ran got together and praised without reservation.

This is also a helpless move, the ancients said, know yourself and know that you will not be defeated in a hundred battles. The views I gave at the meeting were drawn from reading the materials in the past few days, and they were not groundless, but the argument for off-target mutations was not rigorous, and there were at least three loopholes. ”

Jiang Weiguo heard it and asked casually: "Which three?" ”

"For one, gene editing is not the editing of all animal base pairs, and the number of off-target effects is not as exaggerated as the conference calculated."

"Second, off-target mutations are not directional mutations but random mutations, but the three-headed beasts in Chicago, with almost the same direction of growth and evolution, all show strong aggression. If one is fine, all three, the odds are very small in terms of probability. But the application of probability to genetic mutations is not completely reliable, for example, someone buys a lottery ticket all their lives and does not win, and someone buys it for the first time and wins five million. ”

"Third, the consequences of off-target effects are not only off-target mutations, but also cytotoxicity. ZFNs have been shown to be more cytotoxic than TALEN methods or CRISPR-Cas, i.e., the higher the number of off-targets, the more cytotoxic they are. ”

Jiang Weiguo asked curiously at this time: "Then why did you only mention off-target mutations at the meeting?" ”

"I did it on purpose!" Qin Ran cleared his throat, "Before the cause of the three-headed giant beast in Chicago is found, the consequences of both off-target effects may exist, since this is the case, then why don't I choose the one that is beneficial to us, after all, the toxicity can be eliminated after all, but the mutant human is difficult to control." As long as off-target mutations exist, it is difficult for gene editing technology to be widely accepted by the scientific community. ”

"So, you also deliberately provoked Li Zhimin at the beginning?"

Qin Ran nodded silently.

"Alas!" Jiang Weiguo sighed lightly, "Qin Ran, I think you have changed a lot, when we met for the first time, you gave me the feeling that you were a very pure scientific researcher, but now, you have begun to work on scheming." ”

"Actually, I just want to be a pure person, and let the design, construction and piloting of mecha constitute the whole of life, but the academic world is not so pure. So, as the law and morality allow, I can only choose to do whatever it takes. ”

.........

On the other side, experts and scholars in biological genetics gathered, and everyone had a bitter face.

And Li Zhimin was also there, his face was black, and his face was so gloomy that he was about to drip water.

No one expected that the symposium had just begun, and they had not yet launched a formal charge before they were stolen by the enemy.

Regarding the research of the three-headed giant beast, the academic community of his biological genes has not yet come up with a specific conclusion, but a layman has given a response in advance, isn't this a slap in the face of Chiguoguo?

The point is that the other party is not talking nonsense, the arguments are well-founded and convincing, and this is embarrassing.

But as the backbone, Li Zhimin had to appease everyone.

"Don't worry, it's not a big deal for a moment, the symposium will be held for three days, and we have time."

Li Zhimin's reassurance was still useful, and someone immediately suppressed his frustration and put forward his views on the morning meeting, "Director Li, I think that Qin Ran is drilling the tip of the bull's horns and deliberately misleading us all, and the consequences of the off-target effect are not only off-target mutations, but also may produce cytotoxicity. The performance of the three-headed beast in Chicago is closer to poisoning than off-target mutation, and our research on the blood orchid five years ago is also because of ......"

The more he spoke, the quieter his voice became, as if he was scrupling about something.

In fact, everyone around him guessed what he was afraid of, five years ago, it was Li Zhimin's blood orchid research team that had a major accident, which led to genetic contamination, which made Li Zhimin have to move from a research position to a management position, and it is a happy thing for ordinary people to be able to go to a management position, but for Li Zhimin, who has been engaged in scientific research for decades, it is a shame.

In front of Li Zhimin, he brought up the old matter, which undoubtedly rubbed salt on his wounds.

Unexpectedly, Li Zhimin's reaction was very flat, and he seemed to have been downbeat for a long time.

"Do you have any information on that?"

"Yes, but it takes time to sort it out, after all, I didn't expect it to come in handy before attending the meeting. It's just that Qin Ran has already taken the lead in the morning, and I'm afraid our information is not very useful. ”

"Not necessarily, scientific research is not based on seniority, and it is not always on a first-come, first-served basis."

Hearing this, everyone present was quite surprised, don't you always like to talk about seniority?

.........

"How?" Shortly after the morning meeting, Li Liping called Wang Xuezheng, and although he was in the hospital, he was still very concerned about the academic forum.

"Your student is not trivial, it is unexpected, he alone has made the whole expert in biological genetics lose his temper. Who would have thought that Qin Ran also had a very high level in biological genetics, and this time Li Zhimin's gang suffered a dark loss. With such a good start, the next meeting will be much easier, maybe it will really make him break the other party's teeth..."

.......

He Fei is very annoyed now, very annoying, almost annoying.

It was only from Qin Ran who suddenly appeared in the morning and made amazing remarks, which not only caused a sensation among the people on the scene, but also caused a sensation in the live broadcast room.

"Anchor, who is your brother Qin?"

"Damn, there are really people who can build mechas, gods!"

"Anchor, introduce Brother Qin, I want to apprentice, and I also want to build mecha."

"Is he a mechanic or a biology student, why is he so good?"

"The upstairs are all big guys, I listened to it for more than an hour, didn't I understand what was being said?"

"At first, I thought that Brother Qin was standing up and preparing to fight, who would have thought..... I'm sorry, ignorance limits my imagination. ”

......

In the live broadcast room, netizens did not leave Qin Ran in three sentences, which made He Fei depressed, who is the anchor?

For Qin Ran, He Fei went from surprise to admiration to shock at the beginning, after all, unlike netizens, he could clearly feel the aura atmosphere at each point in time when he attended the meeting. But netizens want to ask Qin Ran's identity, how can He Fei know, he only knows that Qin Ran is very good B, but he can't say how Niu B is.

To tell the truth, after discovering Qin Ran Niu B, He Fei really wanted to make friends with the other party, after all, with such a Niu B character, he also had face when he said it. It's a pity that as soon as the meeting ended, he left with an old man and didn't give him a plane meeting at all.

"It's so melancholy!" Seeing the statistics of the highest peak of the live broadcast room, as well as the invitation sent by the video website, He Fei couldn't help but hook the corners of his mouth and showed a satisfied smile.

"I didn't expect that I would become a popular anchor one day."

Of course, He Fei also knew that Qin Ran had at least half of the credit in the middle, but because of this, his desire to befriend Qin Ran became more urgent.
