"Yang Rui, if you don't come back, the scholarship will be swallowed up." Bai Ling tried to make her tone look more urgent, but she still seemed too soft on the phone.

Yang Rui shook his head, which was a little wrong in trying and making mistakes, and asked: "What scholarship?"

Bai Ling was impatient to tell the "coup" that happened not long ago, and then said: "What are you doing? At least show your side in class."

Yang Rui was amused and angry and said, "Forget it, just give it to him if he wants it. I didn't want a scholarship either."

"Even if you don't get a first-class scholarship, it's not Geng Jian's turn." Bai Ling said, "Geng Jian is now looking for a counselor. If you don't show up again, he may go to the department to complain, and maybe he will say something to you. You'd better take the time to come to the school to see it."

Yang Rui was really tired after doing the experiment for several days. He thought for a while and said, "I'll arrange my work and I'll go back to school on Monday."

The current work of Huarui Laboratory is to constantly trial and error, and at the same time, it also constantly reproduces genetically mutated fruit flies. Yang Rui found some means to save time as much as possible, but repeated attempts are indispensable.

As a future big-name player, Huang Mao's intuition in experiments is much better than Yang Rui. During the period when Yang Rui was away, he also completed about 3% of the progress, which can be said to be quite excellent. Yang Rui had nothing to worry about handing over the experimental work to him.

In fact, in addition to being slightly better in direction, Yang Rui is not confident that he can beat Huang Mao.

However, the work of the laboratory owner is more directed.

Yang Rui provided the experimental direction, determined the experimental plan, and proved the experimental results. Even if he did not participate in the experiment significantly, no one would question it as the first author of the paper.

During the two days of the weekend, Yang Rui re-optimized the experimental plan. After verification, he handed it over to Huang Mao again and said, "I'll go back to school. Do you have to work harder and see if you can speed up the progress."

"I'll try my best. To be honest, the research speed has reached its limit. As I said before, if you want to make a paper 4 months ago, the chance is really not high, and the time is too tight... Well, wait, it's interesting..." Huang Mao looked up suddenly and looked at it again on the experimental plan provided by Yang Rui.

Yang Rui sat on the chair with peace of mind, smiled slightly, without showing too much.

To study the role of a gene, you can induce mutations to the gene, and then look at the behavior of the organism or biological system that changes, and you can judge the role of the gene.

This is actually very similar to repairing a computer. When there are two computers, if one computer has problems, the hardware of the computer that has problems will be removed one by one, and replace it with another to determine the hardware of the normal computer. If you try it one by one, the computer will not work properly when you replace it. You can naturally know whether there is a memory problem, a motherboard problem, or a hard disk, CPHJ…¨

Unlike computer repair, organisms have many genetic functions and are difficult to detect one by one.

Sometimes, researchers have to design some clever or tortuous ways to detect two, three, or five, and six factors at the same time, and finally use mathematical methods to determine the problem of one or several of them.

These clever methods did not fall from the sky, but were developed by researchers from generation to generation, attempts and even accidents.

When Yang Rui was studying for a postgraduate degree, many methods had become basic skills.

But in 1984, Yang Rui became a pioneer in cloning mutation gene method. The method he was once familiar with, or was not familiar with, but was naturally not invented.

In recent days, Yang Rui has also been experimenting and selecting common technologies.

The more advanced the technology, the better it is. First of all, the laboratory equipment needs to be coordinated. After 26 years, it is normal to specially equipped a centrifuge of 86-turn 1060-turn for several students. There is no such condition in domestic universities in 1984.

Not only should the hardware requirements be low, but the software requirements should not be too high.

Apart from Huang Mao, Tu Xian, Wang Xiaoyun and Wei Zhenxue's experimental level is relatively average, and they are among the people who are inferior to the top and have more than the bottom. Many techniques that emphasize skills are very tiring to let them operate.

A set of combined techniques does not have only one step. If the accuracy rate of a series of difficulties is only 8%, then the final accuracy rate of the seven difficulties will be only 2%.

In biological experiments, experiments with high technical difficulty requirements are really high. For example, cloning and cloning techniques are basically public, but the laboratories that can clone sheep, pigs, and rabbits can be found all over the world, and the number of laboratories that can be done is not necessarily impossible. They may just be afraid of difficult action requirements, complex experimental steps, and the costs and benefits that are not worth the cost.

Now it’s not long since the cutoff point. Not only do you have to choose those with low hardware requirements and simple operating conditions, but you also have to choose those that are fast or don’t need to learn.

With so many restrictions, Yang Rui can choose not many.

But at least there are also some. Oligonucleotide-induced gene mutation technology is one of the site-directed mutation technologies that have developed rapidly since the late 80s.

This technology was invented in / year, but it was in the perfect period throughout the early 8th century. Huang Mao had also been exposed to it, but it was not commonly used because although oligonucleotide-induced gene mutation technology greatly increased the accuracy of mutations, in actual applications, incomplete in vitro synthesis, destruction of mutation primers by in vitro reactions, etc., all make this technology very troublesome.

In response to these troubles, Yang Rui used a short narrative text to clearly give a solution.

The first is nucleosidase digestion; the second is alkaline sucrose gradient ultracentrifuge; the third is gel electrophoresis under the existence of ethidium bromide, the fourth is cesium chloride density gradient centrifuge; the fifth is hydroxyapatite adsorption single-strand.

Seeing this document that was written incredibly specific, meaningful, and proposed five solutions in one breath, Huang Mao's head sounded "buzzing", as if a hole was opened in his forehead, and rain poured in, stirring and stirring in his brain, causing thoughts to burst out, create, disappear, and create.

After about ten minutes, Huang Mao read the plan and then, sweating on his forehead, and said, "How did you think of these methods? You haven't been in the laboratory for a few days."

"I'm going home for the New Year, and I'm not idle either." Yang Rui was indeed not idle, but was doing the experiment of coenzyme Ql0.

Huang Mao nodded and shook his head, "It's normal for you to research these methods, but I didn't expect you to study them so carefully. OK, I'll try it with your plan, and our progress is just here."

Yang Rui smiled and nodded, thinking: Of course it's just right. I've provided you with this technical solution just because I saw you stuck here.

After practicing with Huang Mao and others for two more days, he settled in the laboratory before Yang Rui returned to school to attend class.

In the first class on Monday, Yang Rui almost rushed into the classroom while stepping on the class bell.

The whole room was filled with students looking at Yang Rui with different expressions.

If it were someone else, the students might not be able to recognize him, but Yang Rui was too conspicuous. Although he is not wearing bright Adidas now, even an ordinary turtleneck sweater can be unique when worn by a high-looking player like Yang Rui.

What's more, Geng Jian has been promoting Yang Rui's privileges these two days.

The teacher on the podium also knew Yang Rui, and smiled gently, saying, "Come early next time in class."

Turning his head, this person started giving a lecture.

Four classes were arranged on Monday morning. Yang Rui complained about the many classes and looked for information in his mind. Now he is used to making his time arrangements extremely fulfilling. It rarely happens to him when he is idle.

When the bell for lunch break rang, Geng Jian stepped onto the podium agilely and said, "Students, please wait a moment, we have to vote and rate a score."

The teacher was still on the podium and looked at Geng Jian and said, "Come to come to my office if you have any questions, and the get out of class is over now."

The teacher left, and the students packed their own things and waited to listen to the arrangements.

Yang Rui looked at the people in the classroom and couldn't help but sigh: The students in the 8th were just good. If it were three years later, how could they wait in the classroom and be quiet?

Geng Jian stood in the center of the podium, coughed hard, and said, "Today, I mainly evaluate the moral education score. The specific situation is everyone already knows. Students who don't know, ask me. I have also talked to the counselor. Our scholarship assessment this time, moral education score accounts for 3 final exams and 6 other honors accounts for 10 comprehensive assessments, from high to low, each class is one first-class scholarship, two second-class scholarships, and four third-class scholarships. In addition, I would like to explain the composition of moral education scores. Moral education scores mainly depend on everyone's usual performance. Among them, sports scores account for 10 moral education scores, social activities account for 40 moral education scores, attendance accounts for 6 moral education scores... Yang Rui, after your attendance, you will get 0 points."

In the last sentence, Geng Jian pretended to be caring and attacked Yang Rui.

Yang Rui was indeed stunned for a moment, then nodded and said, "I understand."

Bai Ling was anxious and didn't bother to avoid suspicion. She stood up from the middle of a group of girls and said, "Yang Rui, don't be provoked by him. You are taking leave to go to the laboratory, and you are not running out to play, so why should you deduct attendance?"

Nowadays, boys and girls are still sitting in groups. Few girls squeeze into the middle of a group of boys, or a boy squeeze into the middle of a group of girls.

Bai Ling was talking to Yang Rui, which immediately caused a gentle laugh, but Bai Ling didn't care.

Seeing this, Geng Jian felt unhappy and was still angry and said, "If he didn't come, he didn't come, and if he asked for leave, he would have been persuaded to leave by the school if he didn't come for so many classes."

Bai Ling wanted to argue for Yang Rui again. Yang Rui smiled and stood up and said, "It's okay, I really didn't come to class, so I should be deducted points, otherwise it will be unfair to other students. Geng Jian, just do things as required."

Bai Ling was stunned for a moment, but quickly reacted and sat down again.

Geng Jian prepared a basket of things and suddenly lost his place to use it.

Bai Ling held the back of the chair with one hand and looked at Yang Rui quietly. One was competitive and the other was calm and gentle, and the other was judged immediately.

As for scholarships or something, it really doesn't matter.

"I haven't been to school these days because the laboratory work is at a critical moment..." Yang Rui's voice sounded again, but he explained seriously: "What I do may have affected some classmates. I should say sorry for this, don't imitate me."

A soft laugh sounded in the classroom.

"Just." Yang Rui clapped his hands again and said, "The foreign factory I contacted gave me a batch of ham sausages and asked me to ask someone to help me taste it. The person who saw it had a portion, one ham sausage. After eating, I told you if it was delicious, and where it was delicious, just write it casually."

As soon as Yang Rui finished speaking, the Jielikang employee who had been waiting at the door brought in two baskets of ham sausages. A stack of paper was placed on each frame.

There were two major students in the classroom, more than one hundred people, looking at the two bamboo baskets that were rising, and they were a little stupid.

Ham sausage is much more expensive than meat, so is it given to others for free? Are foreigners stupid?

"One person, one ham sausage, one evaluation form for each person, don't be polite." Yang Rui grabbed a frame and distributed it one by one.

This is really a sample sent by a foreign factory for marketing. Yang Rui asked Jielikang to buy some ham sausages, and the other party immediately found an affiliated company and gave him free of charge.

Of course, if Yang Rui hadn't called, ten out of ten of these marketing samples would have to go to official marketing.

The evaluation tables that were cut off by Yang Rui were really suitable for the evaluation table.

The student who was just starting to receive ham sausage was a little embarrassed. After taking a little more people, the people behind him would take it naturally.

Some students couldn't bear to eat immediately, and asked loudly: "Can you submit it after the evaluation form?"

Yang Rui immediately agreed: "Just give it to me within three days. If I'm not here, I'll leave it to my dormitory."

"Okay" There was a burst of joyful laughter in the classroom. Almost no one remembered what happened before.

After the two baskets of ham sausages were released, the students' perception of Yang Rui changed greatly. They were all fresh and hot college freshmen, and they had no grudges. Naturally, they decided their preferences based on their personal senses.

It is someone else's ability to be able to go to the laboratory to do things. It is true that you can remember to bring ham sausages to everyone.

When Yang Rui returned to the dormitory building, people kept saying hello to him, and some people were familiar with him and slamming his shoulders and patting his arms.

And in the girls' dormitory, everyone also actively talked about Yang Rui.

"You said that you are good at studying, don't cause trouble, and you can write papers. I can understand this. He gave everyone ham sausages. There are so many ham sausages, and foreign companies are really useless to give him?" Zhao Yan, the lower bunk of Bai Ling, biting the slightly salty casing, and couldn't help but become curious.

The elder sister in the dormitory had a child, so she wrapped the ham sausage with cloth and put it in the cabinet, saying, "The ham sausages made in our domestic factories are made of scraps. Foreign imports are different. I'll give it to everyone to try it. I can understand it. The books that anyone borrowed from the market economy in our dormitory are not written."

"Why did I give it to him?"

"I'm so capable. Bai Ling, do you think so?"

Bai Ling said "Ah" and pretended to be nothing, "I admit that I have the ability, but what I said doesn't count."

"I have the final say. Yang Rui is really capable." The dormitory elder sister laughed and said, "Do you know how much does a ham sausage cost in the friendship store?

"How much?"

"2 yuan per piece."

"How much does those two baskets of ham sausage cost?" The girls in the dormitory seemed to be listening to a surprising story.

"It's not a question of how much money. The ham sausages in the Friendship Store are not something you can buy just by wanting to buy. So, you have to have some ability to buy two baskets of ham sausages. How capable is it to ask foreign companies to give you two baskets of ham sausages?"

The girls seemed to have realized it suddenly.
