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

Yang Rui shook his head that he was a little bit wrong in trial and error, and asked, "What scholarship?"

Bai Ling said anxiously about the "coup d'état" that took place not long ago, and then said: "What are you doing? At least show up in class."

Yang Rui was more funny than angry, and said, "Forget it, just give it to him if he wants it. I didn't want a scholarship in the first place."

"Even if you don't get the first-class scholarship, you won't be able to take Geng Jian's turn." Bai Ling said, "Geng Jian is now looking for a counselor. If you don't show up again, he may turn around and go to the department to file a complaint. I don’t have to say something about you, but you should take the time to come to the school and have a look."

Yang Rui had been experimenting for several days, and he was really tired. After thinking about it, he said, "I will arrange my work and go back to school on Monday."

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

As a future big player, Huang Mao’s experimental intuition is much better than Yang Rui’s. During Yang Rui’s absence, he also completed about% of the progress, which can be said to be quite excellent. He handed the experimental work to him. Yang Rui has nothing to worry about.

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 boss is inherently more directional.

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

During the two days of the weekend, Yang Rui re-optimized the experimental plan. After verification, it was handed over to Huang Mao again, saying: "I will go back to school. 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, if you want to make a paper before April, the chances are really not high. Time is too tight...well, wait, It's kind of interesting..." Huang Mao suddenly raised his head and glanced, again focusing on the experimental plan provided by Yang Rui.

Yang Rui sat comfortably in the chair and smiled slightly without expressing too much.

To study the role of a gene, you can induce mutations in the gene, and then you can determine the role of the gene by looking at which behaviors of the organism or biological system have changed.

This is actually very similar to repairing a computer. In the case of two computers, one computer has a problem, and the hardware of the computer that has the problem is removed one by one, and replaced with the hardware of the other computer that is determined to be normal, so try one by one, to which hardware to replace At that time, the computer can't work normally, and it is natural to know whether there is a problem with the memory, or a problem with the motherboard, or the hard disk, cpu...

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

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

These ingenious methods did not fall from the sky, but were made by researchers who spent their nights and sleeplessly, through generations of developments, attempts, and even mismatches.

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

But at the moment in 1984, Yang Rui has become the forerunner of the cloning mutation gene method. The method he was familiar with or not familiar with but useful but naturally has not been invented.

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

The technology is not that the more advanced the better. First of all, the laboratory equipment must be coordinated. After a year, it is normal to equip a few students with a rotating centrifuge. In 1984, domestic colleges and universities did not have such conditions.

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

Apart from Huang Mao, several people in Huarui's laboratory, Tu Xian, Wang Xiaoyun, and Wei Zhenxue have relatively average experimental levels. They belong to a category of people who are not as good as the top and more than the bottom. Many skills are required for them to operate. It's very tiring.

A set of suitable technology does not only have one step. If a series of difficult points have only a% correct rate, then the seven difficult points will come down, and the final correct rate will be only %.

In biological experiments, experiments with high technical difficulty are really high. For example, cloning, the technology of cloning is basically public, but the labs that can clone sheep, pigs, and rabbits are searched around the world, and the number of laboratories that can be done is counted. Of course, many laboratories that do not do it are not necessarily done. If it doesn't come out, it may just be afraid of the difficult movement requirements, complicated experimental procedures, and the costs and benefits that are not worth the loss.

Now it’s not long before the cut-off point. Not only those with low hardware requirements and simple operating conditions, but also those with fast learning or no need to learn.

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

But at any rate, there are some. Oligonucleotide-induced gene mutation technology is one of the site-directed mutagenesis technologies that developed rapidly after the end of the decade.

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

In response to these troubles, Yang Rui used short narratives and clearly gave solutions.

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

Seeing this writing is extremely specific, there is something to say, and it puts forward five solutions in one go, Huang Mao's head hummed, as if a hole had been opened in his forehead. , The rain poured in, stirring and stirring in his brain, making each thought burst out, creating, disappearing, and creating again.

For more than ten minutes, Huang Mao read the plan again, sweating on his forehead, and said, "How did you come up with these methods? You didn't stay in the laboratory for a few days."

"I have been home for the New Year, and I am not idle." Yang Rui was indeed not idle, but he was doing coenzyme experiments.

Huang Mao nodded and shook his head, nodded and shook his head, and said: "You can study these methods, but it's normal, but I didn't expect you to study so carefully. Okay, I will try your plan. Our progress happens to be stuck here."

Yang Rui smiled and nodded, thinking: Of course it's just right. I just watched you get stuck here to provide you with this technical solution.

After another two days of practice with Huang Mao and others, the laboratory was settled before Yang Rui returned to school.

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 you change another person, the students may not be able to recognize it, but Yang Rui is too conspicuous. Although he doesn't wear brightly colored Adidas now, even an ordinary turtleneck sweater, put on a high-value player like Yang Rui, can be different.

What's more, Geng Jian has been able to promote Yang Rui's privileges vigorously in these two days.

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

Turning his head, this one began to lecture.

Four classes were scheduled on Monday morning. Yang Rui complained about the large number of classes while looking for information in his mind. He is now accustomed to making his time schedule extremely fulfilling. It rarely happens to him when he is idle and staring in a daze. .

When the lunch break bell rang, Geng Jian vigorously stepped up to the podium and said: "Please wait a minute, students, we have to vote and make a score."

The teacher was still on the podium, took a look at Geng Jian, and said, "Students who have problems come to my office. Class is over now."

The teacher was gone, and the students packed their things and waited to hear the arrangement.

Yang Rui looked at the people in the classroom and couldn't help feeling: The students of the age are behaved. After they become adults, how can they wait in the classroom obediently and still quietly.

Geng Jian stood in the center of the podium, coughed vigorously, and said, "Today is mainly to evaluate the moral education score. As for the specific situation, everyone already knows the situation. If you don't know, please ask yourself. Me, and counseling. I have talked about it. In our scholarship evaluation this time, moral education points account for %, final exams account for %, and other honors account for %. The comprehensive evaluation is 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. % Of points...Yang Rui, if you calculate your attendance, you will get o points."

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

Yang Rui really froze for a moment, then nodded and said, "I see."

Bai Ling was so anxious that she stood up from a group of girls and said, "Yang Rui, don't be agitated by him. You asked for leave to go to the laboratory instead of running out to play, so why deduct attendance."

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

Bai Ling helped Yang Rui speak, and suddenly drew a soft laughter, but Bai Ling didn't care.

Seeing this, Geng Jian felt all kinds of unhappy in his heart. He still pressed his anger and said: "If he didn't come, he didn't come, and he didn't come when he asked for leave. If he didn't ask for leave, he would have not come for so many classes, and he would have been dismissed by the school. Up."

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. Points should be deducted, otherwise it would 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.

When Geng Jian prepared a basket, it suddenly became useless.

Bai Ling leaned on the back of the chair with one hand and looked at Yang Rui quietly.

As for the scholarship, 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 seriously: "What I did this may have affected some classmates. I should say about it. I'm sorry, everyone don't follow me."

There was a soft laughter in the classroom.

"It's just right." Yang Rui clapped his hands again and said: "The foreign factory that I contacted sent a batch of ham sausages and asked me to find someone to help me taste them. It’s delicious, where it’s delicious, and where it’s not delicious, just write it casually."

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

There are two professional students in the classroom, more than 100 people, looking at the pile of two pointed bamboo baskets, they are a little stupid.

Ham sausage is much more expensive than meat, so give it away for free? Foreigners are stupid?

"One person has one ham sausage, one person has an evaluation form, you are welcome." Yang Rui grabbed a frame and distributed them one by one.

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

Of course, if it weren't for Yang Rui to call, ten percent of these samples for marketing would go to official marketing.

Those who were cut off by Yang Rui really matched the evaluation form.

The students who just started picking up ham sausages were a little bit embarrassed. After a little more people pick them up, the people behind them will pick them up naturally.

Some students were reluctant to eat immediately, and asked loudly, "Can you pass the evaluation form?"

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

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

After the two baskets of ham sausages were distributed, the students' perception of Yang Rui changed drastically. They are all fresh* college freshmen. They have no grudges or grievances. Naturally, they decide their preferences with their personal senses.

Being able to go to the laboratory to do things is their ability, and it is true love to remember to bring back ham sausages for everyone!

When Yang Rui returned to the dormitory building, he came and went, people kept greeting him, and some people came over and bumped his shoulders and patted his arms~www.wuxiaspot.com~ And in the girls' dormitory, everyone was too. Yang Rui was actively discussed.

"You said, study well, don't cause trouble, and write papers. I can understand that. He gave everyone ham sausages, so many ham sausages, and they are really free from foreign companies?" Bai Ling's lower berth, Zhao Yan, bit Wei Wei. The salty casings made me curious.

The eldest sister in the dormitory has children, so she wrapped the ham sausage with cloth and put it in the cabinet, saying: "The ham sausages made by our domestic factories are all made with scraps. Foreign imports are different. I will give it to everyone to try. Taste, you can understand it. In our dormitory, who borrowed books about market economy, it is not written in them."

"Then give it to him."

"People have the ability. Bai Ling, don't you think?"

Bai Ling said with an "Ah", pretending to be nonchalant: "I admit that I have the ability, but I don't count it."

"I have the final say. Yang Rui is really capable." The big sister of the dormitory said with a smile: "Do you know how much a piece of ham can be sold in the Friendship Store?

"Rich?"

"Two yuan each."

"How much do those two baskets of hams cost?" The girls in the dormitory seemed to hear a surprise story.

"It’s not a matter of how much money. The ham sausages in the Friendship Store are not something you can buy if you want. So, you have to have a little skill to buy two baskets of ham sausages. It’s a great skill to get two baskets from a foreign company ?"

The women seemed to realize it suddenly.
