***********************************

"Yang Rui, if you don't come back, the scholarship will be swallowed up." Bai Ling tried her best to sound urgent, but on the phone, she was still too soft.

Yang Rui shook his head, which was a bit wrong after trial and error, and asked, "What scholarship?"

Impatiently, Bai Ling talked about the "coup d'état" that happened not long ago, and said, "What are you doing, at least show up in class."

Yang Rui was more amused than angry, and said, "Forget it, he can give it to him if he wants it. I didn't want a scholarship at all."

"Even if you don't get the first-class scholarship, it won't be Geng Jian's turn." Bai Ling said, "Geng Jian is now looking for a counselor. If you don't show up again, he might turn around and complain to the department. I don’t have to say anything about you, you should come to the school some time to have a look.”

After several days of experiments, Yang Rui was really tired. After thinking for a while, he said, "I'll arrange my work and go back to school on Monday."

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

Huang Mao, as a future big player, has a much better intuition in experimentation than Yang Rui. During Yang Rui's absence, he has also completed about 100% of the progress, which can be said to be quite excellent. Let the experimental work be entrusted to him. Yang Rui has nothing to worry about.

In fact, apart from being slightly better in direction, the current Yang Rui is not confident that he can beat Huang Mao.

However, the job of a laboratory boss is inherently more directional.

Yang Rui provided the experimental direction, determined the experimental plan, and proved the experimental results. Even if he did not participate in the experiment to a large extent, as the first author of the paper, no one doubted it.

During the two days of the weekend, Yang Rui re-optimized the experimental plan. After verification, he handed it over to Huang Mao again, saying, "I'll go back to school, and you guys will work harder to 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 earlier, the chances of getting a paper published before April are really low. Time is too tight... Uh, wait, Interesting..." Huang Mao suddenly raised his head and glanced at the experimental plan provided by Yang Rui again.

Yang Rui sat on the chair with peace of mind, smiled slightly, and didn't express too much.

To study the function of a gene, the gene is induced to mutate, and then the behavior of the organism or biological system is changed to determine the function of the gene.

This is actually very similar to repairing a computer. In the case of two computers, if there is a problem with one computer, the hardware of the computer with the problem is removed one by one, and replaced with the hardware of another computer that is sure to be normal. When the computer fails to work normally, it is natural to know whether there is a problem with the memory or the motherboard.

Or hard disk, cpu...

Unlike repairing a computer, organisms have so many gene functions that it is difficult to detect them one by one.

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

These ingenious means did not fall from the sky, but were developed, tried, and even made mistakes by researchers who forgot to eat and sleep, generation after generation.

When Yang Rui was in graduate school, many methods had become basic skills.

But now in 1984, Yang Rui has become the pioneer of cloning and mutation gene method. He was familiar with, or not familiar with but useful method, and naturally he has not been invented.

In recent days, Yang Rui is also experimenting and selecting suitable technologies.

The more advanced the technology, the better. First of all, the laboratory equipment must be matched. After 2000, it would be normal to equip a few students with a centrifuge. Domestic colleges and universities in 1984 did not have such conditions.

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

Several people in the Huarui laboratory, except for Huang Mao, Tu Xian, Wang Xiaoyun, and Wei Zhenxue are all relatively average in experimentation. They belong to the category of people who are not as good as the top but more than the bottom. Let them operate a lot of techniques that pay attention to skills is very tiring.

A set of suitable techniques does not have only one step. If a series of difficult points have only a 50% correct rate, then after the seven difficult points, the final correct rate is only 100%.

In biological experiments, experiments with high technical difficulty requirements are really high. For example, cloning, the technology of cloning is basically public, but the labs that can clone sheep, pigs, and rabbits can be searched all over the world, and the number of laboratories that can do it can be counted. Of course, many laboratories that do not do it are not necessarily doing it. If you can't come out, maybe you are just afraid of the difficult movement requirements, complicated experimental steps, and the costs and benefits that are outweighed by the gains.

Now it is not long before the cut-off point. Not only should we choose those with low hardware requirements and simple operating conditions, but we must also choose those that can learn quickly or do not need to learn.

With so many restrictions, Yang Rui can't choose much.

But at any rate, there are. Oligonucleotide-induced gene mutation technology is one of the site-specific mutation technologies that have developed rapidly since the end of the decade.

This technology was invented in 1978, but it was in the stage of perfection throughout the early years. Huang Mao had also come into contact with it, but it was not commonly used, because although the oligonucleotide-induced gene mutation technology greatly increased the accuracy of the mutation, but In practical applications, incomplete synthesis in vitro, damage to mutant primers by in vitro reactions, etc., all make this technology troublesome.

Aiming at these troubles, Yang Rui gave a clear solution in a short narrative.

The first, nucleolisidase digestion; the second, alkaline sucrose gradient ultracentrifugation; the third, gel electrophoresis in the presence of ethidium bromide; the fourth, cesium chloride density gradient centrifugation; the fifth species, hydroxyapatite adsorbs single chains.

Seeing this extremely specific, meaningful, and explanatory document that proposed five solutions in one breath, Huang Mao's head buzzed, as if a hole had been opened in his forehead , The rain poured in, stirring and stirring in his brain, causing ideas to burst out, created, disappeared, and created again.

For about ten minutes, Huang Mao read and re-read the plan, sweating on his brow, and said, "How did you come up with these methods? You haven't stayed in the laboratory for a few days."

"I'm home for the New Year, and I'm not idle." Yang Rui is indeed not idle, but he is doing coenzyme experiments.

Huang Mao didn't doubt that he was there, nodded and shook his head, and said: "It's normal for you to be able to research these methods, but I didn't expect you to be able to research them in such detail, okay, I'll try your plan, That's where we're stuck."

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

After practicing with Huang Mao and others for two more days, after the laboratory was settled, Yang Rui returned to school for class.

In the first class on Monday, Yang Rui almost stepped on the class bell and rushed into the classroom.

A room full of students looked at Yang Rui with different expressions.

If it were another person, the students might not be able to recognize him, but Yang Rui was too conspicuous. Although he doesn't wear bright Adidas anymore, even an ordinary turtleneck sweater can look different on a good-looking player like Yang Rui.

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

The teacher on the podium also knew Yang Rui, so he smiled gently and said, "Come earlier to class next time."

Turning his head, this one started to give a lecture.

On Monday morning, four classes were arranged. Yang Rui complained about too many classes while looking for information in his mind. He is now used to arranging his time to be very full. It rarely happens to him to be in a daze when he is free. .

When the lunch break bell rang, Geng Jian stepped onto the podium vigorously and said, "Students, please wait a moment, we want to cast a vote and give a score."

The teacher was still on the podium, glanced at Geng Jian, and said, "Students with problems come to my office, get out of class is over now."

The teacher left, and the students packed up their things and waited for the arrangement.

Looking at the classroom full of people, Yang Rui couldn't help feeling: the students in the 1990s were obedient, but when they become adults, how can they wait in the classroom obediently and quietly.

Geng Jian stood in the center of the podium, coughed hard, and said, "Today is mainly to evaluate the moral education score. As for the specific situation, everyone already knows it. Students who don't know, please ask yourself. I also talk to the tutor The staff have talked about it, our scholarship evaluation this time, moral education points accounted for %, final exams accounted for %, other honors accounted for %, comprehensive evaluation from high to low, each class has one first-class scholarship and two second-class scholarships , four third-class scholarships. In addition, I will specifically explain the composition of moral education points. Moral education points are mainly based on your usual performance. Among them, sports scores account for % of moral education points, social activities account for % of moral education points, and attendance accounts for moral education points. % of points...Yang Rui, after counting your attendance, you will get 0 points."

In the last sentence, Geng Jian pretended to be concerned in order to surprise Yang Rui.

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

Bai Ling was in a hurry, she didn't care to avoid suspicion, she stood up from a group of girls, and said, "Yang Rui, don't be provoked by him, you are asking for leave to go to the laboratory, and you didn't go out to play, so why should your attendance be deducted?"

Nowadays, boys and girls still sit together, and it is rare for a girl to squeeze into a group of boys, or a boy to squeeze into a group of girls.

Bai Ling helped Yang Rui to speak, which immediately attracted light laughter, but Bai Ling didn't care.

Seeing this, Geng Jian was filled with all kinds of displeasure, and suppressed his anger, saying: "If he didn't come, he didn't come, and if he asked for leave, he didn't come. If he didn't ask for leave, he would have been dismissed by the school long ago if he didn't come to so many classes. gone."

Bai Ling wanted to argue for Yang Rui again, Yang Rui smiled, stood up and said, "It's okay, I really didn't come to class, I should deduct points, otherwise it will be unfair to other students. Geng Jian, just follow the rules."

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

Geng Jian prepared a basketful of words, which suddenly became useless.

Bai Ling leaned on the back of the chair with one hand, and looked at Yang Rui quietly. One of them was competitive, while the other was calm and calm.

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

"I haven't been able to come to school these days because the work in the laboratory is at a critical juncture..." Yang Rui's voice sounded again, but he explained very seriously: "I may have affected some students by doing this, and I should say something about it." I'm sorry, everyone, don't imitate me."

There was light laughter in the classroom.

"Just right." Yang Rui clapped his hands again, and said: "The foreign factory I contacted sent a batch of ham sausages. Let me ask someone to help taste it. Anyone who meets me will have a share. Let's talk about the ham sausages after eating. Delicious, where it is delicious, where it is not delicious, just write whatever you want.”

As soon as Yang Rui finished speaking, the staff of Jiekang who had been waiting at the door brought in two baskets of ham sausage. There is also a stack of paper on each frame.

There are two professional students in the classroom, more than one hundred people, looking at the two bamboo baskets that are protruding from the pile, they are a little silly.

Ham sausage is much more expensive than meat, so give it away for free? Are all foreigners stupid?

"One ham sausage per person, one evaluation form per person, you're welcome." Yang Rui grabbed a box and distributed them one by one.

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

Of course, if it wasn't for Yang Rui's call, 10% of these marketing samples would go to the official market.

The ones intercepted by Yang Rui really matched the evaluation form.

The students who just started picking up ham sausages were a little embarrassed. After a little more people picked up the sausages, the people behind picked it up naturally.

Some students were reluctant to eat it right away, and asked loudly: "Can I hand in the evaluation form later?"

Yang Rui immediately agreed: "Just give it to me within three days. If I'm not here, let me go to the dormitory."

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

After the distribution of two baskets of ham sausages, the students' perception of Yang Rui changed greatly. They are all fresh and fresh college freshmen, with no grudges or grievances. Naturally, personal preferences are determined by personal senses.

Being able to do things in the laboratory is someone's ability, and being able to remember to bring back ham sausages for everyone is true love!

When Yang Rui returned to the dormitory building, he came and went, people kept saying hello to him, and some familiar people came over and bumped his shoulders and patted his arms.

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

"You said, study well, don't cause trouble, and can write papers. I can understand this. He gave everyone ham sausages. There are so many ham sausages. He is a foreign company. Is it really for nothing?" Zhao Yan, Bai Ling's lower berth, bit her head slightly The salty casings made me curious.

The eldest sister in the dormitory has a child, so she wrapped the ham sausage in a cloth and put it in the cabinet, saying: "The ham sausages made in our domestic factories are all made of leftovers, and the imported ones are different. Give it to everyone to try." Taste, I can understand it, isn’t it written in the market economy book borrowed by someone in our dormitory.”

"Then why give it to him?"

"He's capable. Bai Ling, don't you think so?"

Bai Ling said "ah", pretending to be nonchalant and said: "I admit that I have the ability, but I don't count what I say."

"I have the final say. Yang Rui is really capable." The eldest sister in the dormitory said with a smile: "Do you know how much a ham sausage costs in the Friendship Store?

"Rich?"

"2 yuan a piece."

"How much do 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 you have. The ham sausages in the Friendship Store are not something you can buy whenever you want. So, you have to be able to buy two baskets of ham sausages. It takes a lot of skill to ask a foreign company to send you two baskets." ?”

The girls seemed to suddenly realize.
