What Happened If You Didn't Take The College Entrance Examination? I Recommend

Everyone subconsciously looked in the direction of raising their hands.

I want to see who responds so quickly.

Looking back, it was Lu Shixian and a girl.

Lu Zhiyuan also smiled and said, "You two raised your hands almost at the same time, but the students in the third row are girls, girls are the priority."

Depend on!

Lu Shixian in the fifth row complained and took his hand back, which was so embarrassing.

The girl in the third row quickly stood up and said, "My name is Feng Yanan, and the structure consists of a single sequence, a moderately repetitive sequence, and a highly repetitive sequence."

After listening, Lu Zhiyuan nodded approvingly for the first time: "That's a good answer, and this girl is very careful. When answering the question, she directly added her name, which saved time."

When she sat down, Lu Shixian looked at the girl's back, and it turned out that she was Feng Yanan whom Chen Kuangsheng was so fond of.

Really good!

Of course, what Lu Shixian refers to is that his hand speed is quite fast, it would be a pity not to play games.

Lu Shixian thought he was single for so long, but he couldn't get a girl, which is a shame.

I don't know if he was unlucky or something. For the next few questions, he raised his hand after listening to the questions, but there was always someone who was faster than him.

But as the course progressed, the number of hands raised became less and less.

Finally came the sixth question.

Lu Zhiyuan asked: Bioinformatics databases can be mainly divided into four categories. What are these four categories?

As soon as the voice fell, only four or five people raised their hands at this time.

"Very good, the male students in the fifth row are the first to raise their hands." Lu Zhiyuan stretched out his hand for him to start performing.

Finally got the first question, it was really not easy.

Lu Shixian let out a long sigh of relief and stood up from his seat.

"Hello Professor Lu, my name is Lu Shixian."

"My answer is the genome database, the primary structure database of nucleic acids and proteins, the three-dimensional spatial structure database of biological macromolecules, such as db (protein molecular model database), and the secondary database built on the basis of the three databases mentioned above."

"My answer is over."

After Lu Shixian finished speaking, Lu Zhiyuan nodded to him, motioning him to sit down.

"Although this classmate is a bit long-winded, he is right!"

Lu Shixian: (/&34;≡ _ ≡)/~┴┴

He saw many people smiling and turning their heads to look at him.

But this is a logical standard three-stage structure, okay!

Why are you so long-winded?

But for the sake of that, Lu Shixian didn't take this matter to heart.

Immediately afterwards, after Lu Zhiyuan talked about some knowledge, he started the next round of questions.

"The commonly used nucleic acid sequence database contains dna and rna sequence data, and its data comes from many research institutions, nucleic acid sequencing groups and scientific literature."

"Each record in the database represents a single, continuous, annotated DNA or RNA fragment. It plays an important role in conducting molecular biology research, updating common nucleic acid sequence information, and academic communication."

"So what are the three major international nucleic acid sequence libraries?"

At this time, like Lu Shixian, Wang Fuwen, who had been unable to compete with others, began to work hard on this kind of problem that required a strong knowledge storage capacity.

He raised his hand in front of Lu Shixian and got a chance to answer.

"Wang Fuwen, nbank, ebl, ddbj."

After speaking, he sat down directly.

Lu Zhiyuan raised his head and glanced at him, feeling a little dumbfounded.

Just finished talking about the last classmate who was too long-winded, but this one simply cherishes words like gold.

But he still nodded and said: "Yes, this student's answer is correct!"

"Now let me introduce the three major nucleic acid sequence libraries."

"nbank (gene bank) was established by ncbi (National Center for Biotechnology Confidence), and now it has become the most important and influential database for research in almost all biological fields, and its data is used by millions of people around the world Researcher access and citations. The current nbank continues to grow at an exponential rate, doubling almost every 18 months."

"Ebl (European Molecular Biology Laboratory) is a molecular biology research institution. As early as January 1998, the number of sequences included in ebl has exceeded one million, including 15,500 species, of which more than 50 are sequences of model organisms .”

"DDBJ (Sun Country DNA Database) is an accounting sequence database that collects DNA sequences, located at the National Institute of Genetics (NIG) in Shizuoka Prefecture. It is also a member of SDC, the international nucleotide sequence database organization."

Speaking of this, Lu Zhiyuan's tone suddenly became low.

"In 1988, the three major gene banks came to an agreement to exchange data on a day-by-day basis. It can therefore be assumed that all three databases contain the same data at any given time."

"But I don't know if you have discovered that even the Sun Country has a nucleic acid sequence library, but our country has not joined it."

"And these are very important basic biological data. If the international situation becomes tense, these foreign databases are stuck for us, and open source data are not open to us, what should we do?"

At this time, almost everyone began to fall into deep thought.

When Lu Zhiyuan said this, the class stopped for a minute for the first time.

After the time passed, he began to pick up what he had just said.

A few more questions were raised during the period, and by this time, the whole class was almost a two-word classroom between Wang Fuwen and Lu Shixian.

However, if you can see the data on the notebook registered later, you will find that Lu Shixian still has the upper hand in the number of times.

Finally, Lu Zhiyuan raised the watch on his left hand, glanced at the time, it seemed that the time was almost up, so he was about to end the class.

"Although many bioinformatics institutions and bioinformatics systems have been established in foreign countries."

"But fortunately, we have also begun to pay attention to the important commercial value of biological information. At present, we have built the human genome south and north centers one after another. In addition, Yanda has also built a bio-city project."

"In the future, our country will also be able to obtain huge benefits in terms of shortening the drug development cycle and rushing to register gene patents by obtaining biological information and data and researching and utilizing them."

"I believe that day is not too far away."

After saying this, Lu Zhiyuan finally opened the teacup and moistened his throat.

"Okay, that's all for my class today. If there are students who are interested in my class, please apply for the Department of Biology, Yanjing University!"

Everyone did not expect that Professor Lu actually advertised in the end.

Three seconds later, the whole classroom burst into warm applause.

Almost everyone in the classroom was overwhelmed by his profound professional knowledge, as well as his spiritual qualities that ordinary teachers do not possess.

A real teacher should not just talk about what is in the textbook.

Likewise, real knowledge doesn't just always appear in the classroom.

And he did!
