Rebirth of the God-level Xueba

Wang Dongming entered the teaching area with a mouthful of buns and a mouthful of soy milk, walking slowly.

The girl who was traveling with her was in a hurry, she gritted her teeth and said, "Eat the buns as long as you eat them, you can't hurry up."

Wang Dongming shook his head: "Do you know when I am most comfortable every day? Even when I have breakfast in the morning, the Emperor and I can't stop me from eating buns."

"You look like a wealthy landlord." The girl said angrily, "If you want to eat breakfast comfortably, why can't you get up early and go to the cafeteria to buy it?"

"Wake up early just to have breakfast, that's not comfortable, that's a toss."

"Okay, you deserve me to buy you breakfast?" The girl snorted and turned her head away.

Wang Dongming swallowed one-third of the buns in one gulp, swallowed hard, and said with a smile: "You don't call it a toss when you go to buy buns, this is called..."

Even though he is a brave boy, when he said this word, he still used English unconsciously and lowered his voice.

The girl's face turned red, and she said coyly, "You...what nonsense!"

"Don't talk nonsense, actually, I just don't have the money to buy buns. I thought about it, you're an idiot, a pair of leather shoes cost two or three hundred, so I'll just let you pay for it..." A little Boys who are not ashamed or inferior because of money are also rare, and this one is even more righteous and has the temperament of an adulterer.

The girl asked seriously, "You spent all your money again? What did you buy?"

"I didn't buy anything..."

"Say that the love flower of a prostitute is poisonous." The girl put her fingers on Wang Dongming's waist.

"Really no... ouch, you really pinched, yes, I said, I said, I bought two tapes, typed, cheap, only 10 yuan a disc, and it cost thirty..."

"10 yuan for one set, 30 yuan for two sets, Wang Dongming, can you be serious if you lie to me?"

"Two plates are an approximation, an approximation... oops..."

"What tape?"

"The country music sung by foreigners is very exciting." Wang Dongming showed a ruffian look.

The girl blushed inexplicably.

A ruffian who plays music is not considered a ruffian in this era. He is a rebellious and talented high-level talent with a faint halo on his body—a ruffian who was able to learn music in the 1980s had to be from a fairly good family background. This is like asking how much a parking space in your community costs per month. It is a tactful background proof. Those who play music in college are even more powerful.

Of course, it takes a little wisdom to catch such a boy. The girl flicked her hair with a few words of coquettishness, and stomped on the ground with more than two hundred Dongdan limited edition calfskin shoes. Ask about the boys' favorite topics: "What kind of tape do you like so much? What are the lyrics?"

"What can foreigners sing in country music, just like in our Chinese village, you stole my first love, I slept with your sister-in-law, don't look at my wife, his son looks like me..." Wang Dongming said casually Hum a couple of American country tunes.

"Bah, if you keep talking nonsense, I won't go with you." The girl took two quick steps and stopped at the door of the classroom without going any further.

Satisfied, Wang Dongming happily took a big bite of the bun and said with a smile, "I knew you wouldn't leave me."

while saying,

As he stepped through the classroom door, he also froze.

"Did we go to the wrong classroom?" Wang Dongming murmured with a bun stuffed in his mouth.

"Is this classmate taking a genomics course?" The teacher at the door asked kindly, looked at the steamed stuffed bun in Wang Dongming's mouth, and then turned his head slightly: It's too ugly!

Wang Dongming nodded stupidly, and asked again: "Have you changed the classroom for genomics?"

"No, if you are a student of this class, you can go in, if not, don't come in, have you brought your student ID?"

"I haven't heard that they check their student ID cards in class." Although Tsinghua students are obedient, they are not so obedient that they don't talk back.

The teacher laughed dryly and said, "Too many people came to class today, and I can't let it go. If you are not students in this class, come back another day."

"Come back another day, can the teacher repeat today's lesson?" Wang Dongming said dissatisfied.

The teacher smiled and said, "If you have a student ID card, just show it."

Wang Dongming wiped his mouth and took out his student ID card from his pocket with oily hands.

This thing has a wide range of uses, and students, especially freshmen, often carry it with them.

The teacher looked carefully, then lowered his head to look in the notebook in front of him, then nodded and said: "Seats four in the eighth row, don't go astray."

"Is there still a row of seats?"

"If there are too many people, we have to line up the seats. Don't talk nonsense when you go in. There are cameras." The teacher reminded him and motioned him to go in.

Wang Dongming was startled once by the camera. He poked his head in and saw a big camera in front of the classroom, supported by three legs.

"There were no cameras in the first few classes, dandy Wang Ye Qin Mei Ji." Wang Dongming walked to the middle of the classroom muttering, found the eighth row and four seats, then turned to look at the seventh row where his girlfriend was, and slapped him. Say hello and sit in.

After sitting down, Wang Dongming was surprised again when he looked at the front and back rows.

"Hello, Teacher Liu." Wang Dongming sat up straight when he found that his biochemistry teacher was right in front of him.

"Hi, come earlier next time. Director Yang will be in class soon." Teacher Liu didn't know who Wang Dongming was, but he knew that he was a student in his class, so he criticized in a decent manner.

Wang Dongming nodded obediently, then looked down at his watch: 7:55. There are still five minutes until class starts.

Wang Dongming couldn't help slandering in his heart: the big class at night is so good, the two of us go to class together after dinner, and after class, we can send the girl back to the dormitory in the dark...it feels completely different if it is changed to morning, okay? The singer goes to bed before 12 o'clock in the evening? Waking up after 7:00 a.m. can kill you.

Looking left and right, Wang Dongming was even more frightened by two familiar or unfamiliar teachers.

"What happened?" Wang Dongming couldn't figure it out.

After a while, Yang Rui pushed the door open and entered, and was slightly surprised when he saw the scene in front of him.

However, Yang Rui didn’t know how many times he faced the camera, so he started the class very calmly, and said: “Today we will focus on cloning and cloning, and introduce the methods used to study individual genes in the pre-genome era. After that, I will focus on introducing , a research method dedicated to genome, after class, you can compare the differences and advantages and disadvantages of the two methods, as an after-class homework, we haven't assigned homework yet."

"No." The students answered in unison obediently.

Yang Rui cheerfully said "Okay", feeling that the new students are really well-behaved. At the same time, he consciously or unconsciously faced the camera and said: "In the 1970s, the techniques used by molecular biologists to study DNA molecules had already A mature set of tools has been formed. Although the classical genetic method is the only way to study a single gene, many fundamental discoveries in molecular biology have also been made in this way. For example, in 1961, and the proposed operon Theory, which describes how the expression of certain bacterial genes is regulated, is probably the greatest achievement in the field of genetics of this era... However, the limitation of classical methods is that they cannot directly detect genes, that is, Say, all information about gene structure and activity is inferred...By the late 1960s, these indirect methods were not enough to answer the detailed questions of individual gene expression asked by molecular biologists... ...At this time, dna recombination technology appeared."

When Yang Rui said this, many experts and professors unconsciously raised their heads.

The classical genetics method is actually the main method, or even the only method, used by many scholars today when doing research.

Of course, everyone knows that this is a foreign technology in the 1960s, but everyone either only knows this method, or only has this technical condition.

At this time, Yang Rui's naked classical genetic method is not enough and has been eliminated by DNA recombination technology. Many people cannot accept it emotionally.

Some people even complained unavoidably: What's the matter, I use the old technology, so it may not be possible to produce better results than you.

However, the complaint disappeared quietly the moment his eyes touched Yang Rui.

After so many days of understanding, everyone is already familiar with Yang Rui's research work and cannot be more familiar with it. As far as scientific research itself is concerned, no one dares to speak out against Yang Rui in the field of genetics at this moment.

What's more, there are cameras filming it.

In the classroom, undercurrents surged.

At the scene, it was calm.
