"What the hell?"

"Why...why is there no one?"

The revival of the early morning,

Xu Mang was walking on the way to the laboratory and found that the school was empty.

Sitting on the chair in the office, he took out the experimental data of the three previous postdocs. This was already the n+1 time for repeated comparison. Xu Mang had not made any progress before, but this time it was similar, except that it had become

It's just a habit.

"perhaps..."

"My thinking is wrong." Xu Mang frowned, took out his notebook from his bag, connected to the Internet, and opened the database of the Institute of Biochemistry and Cell Biology of the Academy of Sciences. Xu Mang planned to replace the DNA fragment with

Target sequence issues are collected centrally.

"well?"

"Wait a moment!"

"Why do I keep staring at the problem of replacing DNA fragments with target sequences?" Xu Mang suddenly woke up. He found that he was a little too stubborn on the issue of replacing DNA fragments with target sequences. This problem can be completely bypassed.

past.

An immature idea came up. First, a DNA strand is cut and the target sequence y is inserted. Then the original sequence is cut out, and then another DNA strand that has not been edited is cut. Finally, the CRISPR system repairs the cut DNA strand.

This is Xu Mang's initial idea. Like the CRISPR-Cas9 system, Cas9 is used to recognize specific DNA sequences, but Cas9 has been modified to only cut off one DNA strand, and then the reverse transcriptase is guided by the RNA strand at the cut site.

Gene editing.

"Yes!"

"I'm gradually starting to feel it!" Xu Mang suddenly gained a new life, but this new feeling only lasted for about ten seconds, and it suddenly disappeared. If we follow this idea, it seems that a lot of research and experiments are needed, but

I don’t know how to study biology.

Looking for Xiaoman?

Xiaoman majored in economics and was terrible at biological experiments.

"what to do?"

"How about...finding Academician Zhong?" Xu Mang took out his mobile phone and dialed the number.

beep,

called out,

Xu Mang hung up immediately.

Shouldn’t this be the time for ‘Xu Man System No. 2’ to appear?

...

night,

always comes quietly,

Yang Xiaoman had just thrown all the clothes into the washing machine and was about to go back to the living room to watch TV, but found that Xu Mang, who was supposed to be paralyzed on the sofa, was missing.

"What's going on?"

"Where is this guy?" Yang Xiaoman frowned, thinking that he seems to be struggling with the progress of scientific research recently. Could it be that... he has found a solution to the problem?

Tiptoeing to the door of Xu Mang's study, Yang Xiaoman gently opened the door a crack. Through this tiny crack, Yang Xiaoman found Xu Mang sitting in front of the computer, typing on the keyboard solemnly. After a while, he lowered his head and picked up the pen again.

I don’t know what I’m calculating on paper.

Xiaoman closed the door silently, helplessly with a hint of love.

The annoying big bad guy!
