"What if we want to find a specific piece of DNA?"

"This can be done with a specific restriction enzyme called EpFect, which is extracted from human E. coli and can intercept specific DNA fragments!"

"When we get the specified DNA fragment, we can copy the DNA, replicate it, and then add it to human cells, and in this process we need the virus to transcribe the DNA......

"After a piece of DNA is transcribed into human cells, it will spread in the human body, and now we will talk about how to control the spread of DNA, here we need to add specific resistance genes to the plasmid, such as penicillin......"

"The addition of antibodies to the specified plasmid allows us to control the effect of transcription more precisely, ensuring that only one plasmid is absorbed by a virus, which is very important, and I hope you will keep in mind, so let's move on to ......."

"That's all for today, class!"

With Park Dong-hyun's voice, the students in the class began to disperse one after another, and Park Dong-hyun packed up his things and walked out of the classroom to his office.

"The strain I cultivated yesterday should have grown to a sufficient number now for me to carry out the next experiment!" Park Dong-hyun thought as he walked, and soon came to his office, and just as he was about to enter the office, Park Dong-hyun heard a voice coming from the office, and it seemed that someone was talking about him, and Park Dong-hyun stopped.

"Do you know? Yesterday I saw Dong-hyun and the man come out of the lab at around 1 a.m., what do you say they are doing in the lab?"

"What else can I do, what can a lonely man and a widow do?"

"Don't talk nonsense, Dongxian is engaged in scientific research, isn't it normal to be busy until night?"

"Doing scientific research with a man?"

"You said that if these two people don't have anything, why did the man invest so much money, 10 million US dollars!"

"Even if the two of them have a little relationship, Donghyun doesn't have a boyfriend, I think you are jealous!"

"I'm jealous of her, how can it be, I just can't get used to it!"

"What's not to be used to!"

"Don't you think Dongxian is eating tender grass from an old cow? She's in her 30s this year, and the man is in his 20s at most!"

"Don't you say you're jealous, aren't you just envious that Dongxian has found a tender and rich boyfriend?"

"What a boyfriend, I think it's a concubine!"

"You just can't see the good of others!"

"Hey, what do you mean by that, I'm just telling the truth!"

"You're jealous!"

"Yes, I'm just jealous, so what, aren't you jealous?"

“……”

Park Dong-hyun's chest continued to rise and fall outside the door, and as soon as he turned around, he left the office, and on the way to the campus, Park Dong-hyun kicked a tree hard, which calmed down a little, and then walked towards the laboratory building.

Swiping the card into the door, Park Dongxian saw at a glance that Wu Ren was engrossed in the experiment in the laboratory, and the focused expression made Park Dongxian stunned, and he couldn't help but think of the words discussed by his colleagues just now, this Wu Ren is really handsome, although he can't be said to be a little fresh meat, but it doesn't seem to be too much of a problem to say that he is a fresh meat.

In the past three months, Park Dong-hyun has not thought about this at all, all his energy has been focused on teaching Oh In-ho research topics, and today's discussion with colleagues behind the scenes made Park Dong-hyun suddenly find that this man who is much younger than himself seems to be really handsome, but it would be too annoying to say that Park Dong-hyun is an old cow, Park Dong-hyun is only 30 years old this year, and he is usually busy with classes and experiments and has no time to dress up, if he dresses up, he is definitely not worse than those little girls in their 20s.

At this moment, Park Dongxian saw Yang Qing standing up and catching a mouse from the breeding box, and then saw Wu Ren holding the mouse in his hand and turned his head and said with a smile: "Teacher, when did you come, I didn't hear a little movement!"

"I didn't bother you when I saw that you were doing an experiment!" Park Dong-hyun replied, but after saying this, he felt weak for a while.

"What kind of experiment are you doing?" Park Dong-hyun put down what he was holding and walked up.

Yang Qing had already grabbed the mouse and came to the injection table at this time, and said while fixing the mouse: "I just transcribed a piece of DNA, and now I'm going to see if the transcription is successful!"

"What a fragment!" Park Dong-hyun asked casually.

Yang Qing had already picked up a needle at this time, and was absorbing the transcribed virus liquid: "I don't know what it is, I don't know what the specific effect of a piece of DNA I found by accident!"

When Park Dong-hyun heard this, he didn't ask again, but turned to his own research.

Carefully sucking the virus liquid into the syringe, looking at the transparent liquid in the syringe, Yang Qing was a little nervous at this time, the DNA fragment transcribed by the virus liquid was one he chose in the "Human Gene Signature Database".

The book "Human Gene Signature Database" is a companion book to "Gene Editing: Programming Organisms", and it is not enough to master the method to edit genes, but how to accurately find the genes you want to edit is the biggest problem.

According to the programmer, the book "Gene Editing: Programming Organisms" teaches Yang Qing how to program, and the book "Human Gene Signature Bank" records the gene fragments commonly used by humans, which is equivalent to the source code of the program, as long as you follow it.

Injecting the virus liquid into the mouse's body, Yang Qing took out a new glass box, and then put the mouse inside. I looked at the time, 14:25.

Then Yang Qing didn't care about the mice, and it takes time for the virus to transcribe the DNA fragments into the cells of the mice, and the specific time depends on the actual situation.

After dealing with the guinea pig, Yang Qing came to Park Dongxian's side: "Teacher, I'm done!"

Park Dong-hyun was using a microscope to observe something at this time, and when he heard Yang Qing's voice, he said directly: "Help me turn on the centrifuge!"

"Okay!" Yang Qing skillfully turned on the centrifuge placed on the other side of the table.

In the next time, Yang Qing helped Park Dong-hyun do experiments.

Time passed minute by minute, and soon it was afternoon, Park Dong-hyun stood up from the front of the experimental table and said to Yang Qing: "Let's go, let's eat!"

"Hmm!" Yang Qing agreed, and stood up.

At this time, Park Dongxian turned his stiff neck, and suddenly, Park Dongxian seemed to see something, and quickly walked towards the glass box where Yang Qing put the guinea pig.

Coming to the glass box, Park Dong-hyun said loudly: "Oh In, what did you inject the test subject, how did it turn black!"

Yang Qing also came to the glass box at this time, watching the mice inside turn into a little black mouse, Yang Qing secretly said in his heart: "What a magical DNA recombination!"
