Wang Dongming took a bite of buns and a mouthful of soy milk into the teaching area, and his pace was slow. Pen, fun, and www.biquge.info

The girl who was traveling with her was in a hurry, and gritted her teeth and said, "If you eat steamed buns, you can eat steamed buns, it's not okay to go faster." ”

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

"Look at your landlord's old wealth. The girl said angrily: "If you want to eat breakfast comfortably, can't you get up early and go to the cafeteria to buy it yourself?"

"Waking up early just to have breakfast is not comfortable, it is a toss. ”

"Okay, do you deserve to toss me to buy you breakfast?" the girl snorted and turned her head.

Wang Dongming swallowed one-third of the buns in one gulp, swallowed hard, and said with a smile: "It's not called tossing when you go to buy buns, it's called ...... love……”

Although he is a bold boy, when he says this word, he still unconsciously uses English and lowers his voice.

The girl's face turned red, and she twisted: "You...... What nonsense!"

"Don't talk nonsense, don't talk nonsense, in fact, I just don't have the money to buy buns, I think about it, aren't you a high-ranking cadre, a pair of leather shoes are worn for two or three hundred, I'll let you break the bank...... "Boys who are not ashamed at all and are not inferior because of money are also rare, this one is even more righteous and awe-inspiring, with the temperament of a communist."

The girl then asked very seriously, "What did you spend again?"

"Didn't buy anything......"

Say. The girl's finger was placed on Wang Dongming's waist.

"It's really not ...... Oh, you're really pinching, you have to got, I said, I said, I bought two tapes, the mouthful, cheap, only 10 yuan a plate, it cost 30 ......"

"One plate is 10 yuan, two plates are 30, Wang Dongming, can you lie to me seriously?"

"Two sets 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's face flushed inexplicably.

The ruffian who plays music is not a ruffian in this era, and belongs to the unruly and talented high-level talents, and there is a faint aura on his body - the ruffian who can learn music in the 80s has to be quite good, which is like asking you how much a parking space in the community costs a month, which is a euphemistic background to prove that playing music in college is even more powerful, which is basically equivalent to the second generation of the right who has fun, IQ and perseverance.

Of course, to catch such a boy, it also takes a little bit of wisdom, the girl's little coquettishness, just brushed her hair, more than 200 pieces of Dongdan limited edition calfskin shoes on the ground, and asked the boy's favorite topic: "What content tape do you like so much?

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

"Phew, if you talk nonsense, I won't leave with you. The girl took two quick steps and settled at the door of the classroom, not going any further.

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

As he spoke, he stepped through the classroom door and froze.

"Did we go to the wrong classroom?" Wang Dongming stuffed a bun in his mouth, and his voice was muttering.

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

Wang Dongming nodded stupidly and asked again: "Genomics has changed classrooms?"

"No, if you want students in this class to be able to enter, if not, don't come in, bring your student ID?"

"I haven't heard that I still check my student ID in class. "Although the students of Tsinghua University are well-behaved, they are not so well-behaved as not to talk back.

The teacher laughed dryly twice and said, "There are too many people to come to class today, I can't let it go, if you are not a student in this class, you can 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, take it out." ”

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

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

The teacher looked at it carefully, looked down and looked for it in the notebook in front of him, and then nodded: "The eighth row of four seats, don't go wrong." ”

"Still in a row?"

"There are so many people that you have to line up for seats. Don't talk nonsense when you go in, there's a camera. The teacher admonished him and motioned for him to come in.

Wang Dongming was startled by the camera once, and the probe came in, and sure enough, he saw a big camera in front of the classroom, which was framed in the middle by three legs.

"There were no cameras in the first few classes. Wang Dongming muttered and walked to the middle of the classroom, found the eighth row of four, then looked back at the seventh row where his girlfriend was, said hello to him, and sat in.

Sit down, look at the front and back rows, Wang Dongming was shocked again.

"Hello Mr. Liu. Wang Dongming found that the teacher who taught him biochemistry was in front of him, and he couldn't help but sit up straight.

"Hello, next time I come early, 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 the class he taught, so he criticized it in a similar way.

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

Wang Dongming couldn't help but slander in his heart: How good the big class was in the evening, the two of them went to class together after dinner, and they could send the girls back to the dormitory in the dark after class...... Changed to morning, it feels completely different, and which singer goes to bed before 12 o'clock at night? Getting up at 7 o'clock in the morning is almost fatal.

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

"What's going on?" Wang Dongming couldn't guess.

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

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

"Nope. The students replied in unison.

Yang Ruile said "good", feeling that the new life is really well-behaved, and at the same time, he consciously or unconsciously faced the camera, and said: "In the 70s of the 20th century, molecular biologists have formed a set of mature tools to study the technology used in DNA molecules. For example, in 1961, Jacob and Mood proposed the operon theory, which described how the expression of certain bacterial genes is regulated, which is probably the greatest achievement in the field of genetics of our time...... However, the limitation of classical methods is that they do not directly detect genes, that is, all information about the structure and activity of genes is inferred...... By the late '60s, these indirect approaches were not enough to answer the detailed questions of molecular biologists about the expression of individual genes...... That's when DNA recombinant technology came in. ”

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

The classical genetic method is actually the main method, or even the only method, used by many scholars in their research.

Of course, everyone knows that this is the technology of the 60s abroad, but everyone will either only have this method, or only the technical conditions for this.

At this time, Yang Rui's naked classical genetics method was not enough, and it had been eliminated by DNA recombination technology, and many people could not accept it emotionally in the first place.

Some people even can't help but complain: What's the matter, I use old technology, and I may not be able to achieve better results than you.

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

After so many days of understanding, everyone has long been familiar with Yang Rui's research work, as far as scientific research itself is concerned, no one dares to speak out about Yang Rui at this moment, in the field of genetics.

What's more, there are cameras filming.

In the classroom, there is an undercurrent.

The scene was calm.
