"What are you laughing at, if you can't answer, come and drill!"

Seeing Lin Xiaowen's smile, Lao Dou felt very unhappy, and immediately looked at Lin Xiaowen with a sneer, stretched out his finger and pointed to his crotch, and said.

"It's over, fuck off! I don't have time to waste time with you, a kid who doesn't know how high the sky is. Lao Dou said again.

Seeing Lin Xiaowen's expression, the other members of the teaching and research team secretly shook their heads in their hearts, it seems that this kid is empty! What a miracle doctor, but a seller of dog skin plasters! Some secret recipes of traditional Chinese medicine were passed down from the family, so he came out to be abducted and deceived, claiming to be a miracle doctor, but he was really a frog at the bottom of the well, he had no knowledge, and he wanted to join the teaching and research group of the medical university!

"Lao Dou, since he can't answer, forget it, just let him go, stay a line, and see each other in the future." A member of the faculty and research team, sitting at his desk, suddenly spoke.

The meaning of this is to let Lao Dou cancel the requirement to drill his crotch.

Lao Dou waved his hand and said, "Since you have said it, you can't change it, and you are willing to lose the bet." Staring at Lin Xiaowen playfully, there was a sense of joy after the victory.

Only Li Hua felt that something was wrong, this kid smiled so weirdly, it didn't look like he was stumped!

"Huh! When did I say I couldn't answer? Lin Xiaowen said with a smile.

"Then hurry up! Do you still want to go through the information? Lao Dou was sure that Lin Xiaowen was playing tricks, and at this time he was even more victorious.

"Well, if you wish, then please advise." Lin Xiaowen coughed lightly before he spoke: "It is the basic unit that makes up proteins, giving proteins a specific molecular structure and form, and making its molecules biochemically active. Proteins are important active molecules in living organisms, including enzymes that catalyze metabolism. Chemical polymerization of two or more amino acids into peptides, the original fragment of a protein, is a precursor to the production of amino acids from proteins. Broadly speaking, it refers to an organic compound that contains both an alkaline amino group and an acidic carboxyl group, as its name suggests. However, amino acids in general refer to the structural units that make up proteins. In the biological world, the amino acids that make up natural proteins have their specific structural characteristics, that is, their amino groups are directly attached to the α-carbon atom, and this amino acid is called α-amino acids. There are more than 300 kinds of amino acids in nature, of which 21 are α-amino acids. α-amino acids are the building blocks of peptides and proteins, and are one of the basic bricks that make up the edifice of life. The amino acids that make up proteins are a class of organic compounds that contain carboxyl groups and have amino groups attached to the carbon atoms attached to the carboxyl groups. According to analysis, glutamic acid in amino acids is not only an important nutrient for the human body, but also a common drug for the treatment of liver disease, nervous system disease and mental illness, and is effective for liver disease, schizophrenia and neurasthenia. ”

“……”

The eyes of the people present widened, originally thinking that Lin Xiaowen didn't understand anything, but as a result, ......

"This kid!"

Li Hua looked at Lin Xiaowen, a relaxed smile appeared on his face, Lin Xiaowen finally didn't disappoint him, but what he didn't expect was that this kid was not only blessed with attainments in traditional Chinese medicine, but also in modern medicine, he also had not weak attainments, he found that he was getting more and more unable to see Lin Xiaowen clearly, and felt that this kid's attainments in medicine were as unfathomable as the ocean.

I really don't know how this kid can be so old and have such profound attainments, how did he do it?

Lao Dou, who was still proud, suddenly stiffened the smile on his face, and through Lin Xiaowen's methodical explanation, he instantly understood that this kid was playing with himself just now, deliberately pretending to be embarrassed, Nima's, it's too bad!! Hurt Lao Tzu Bai to be happy!

At this time, Lao Dou's heart was itching with hatred, but when he thought of two more problems, he immediately calmed down, after all, he hadn't lost yet, and he still had a chance!

"Mr. Old Bean, do you and I have any insight into the explanation of this amino acid?" Lin Xiaowen saw that everyone didn't speak, so he opened his mouth.

"There's nothing to teach, you're right." The old bean's dough tugged a little, and his tone was a little unwilling.

"Cut! What do you mean by counting, I'm right! That's right, that's right. The corners of Lin Xiaowen's mouth twitched, and he said angrily.

Seeing that Lin Xiaowen had successfully passed a level, Yating immediately clapped her hands happily and said, "Teacher, you are awesome!" Come on! ”

Lin Xiaowen's eyes fell on Yating's fragrant delicate body, and he grinned: "It's necessary, hehe, dealing with this kind of rookie, that's a trivial matter!" ”

Lao Dou heard Lin Xiaowen say that he was a rookie, his face suddenly darkened, and he gritted his teeth and said, "Don't be happy too early, there are still two questions!" ”

What he asked just now was some common sense, and Lao Dou wanted to test Lin Xiaowen's foundation, but Lin Xiaowen answered very fluently, and he knew that this kid was indeed a little bit heavy, so when he asked the second question, he put away his contempt and completely regarded the other party as a real opponent.

After all, Lao Dou can't afford to lose, as the elite of the teaching and research group, he is also a first-class figure in the medical field, losing to a kid who is more than 20 years younger than himself, and drilling his crotch, this shameful thing, Lao Dou can't afford to lose.

"Oh! Then please Mr. Bean, continue! Lin Xiaowen stretched out his hand, smiled, and said in a mocking tone.

Lao Dou tidied up his clothes, pondered for a while, and then said: "Second question, you listen well, let's talk about the steps of DNA extraction!" Don't be foolish, just answer when you know. ”

"Oh? All right! There are many methods for extracting DNA, such as concentrated salt method, anionic detergent method, phenol extraction method, water extraction method, and the phenol extraction method is mentioned below, which is used as a protein denaturant and inhibits the degradation of DNase. When the homogenate was treated with phenol, the protein and DNA bond had been broken, and the protein molecule contained many polar groups on the surface that were similar to phenol and soluble. Protein molecules are soluble in the phenolic phase, while DNA is soluble in the aqueous phase. After centrifugation, the aqueous layer was removed, the operation was repeated many times, and then the aqueous phase containing DNA was combined, and the DNA was precipitated with ethanol by taking advantage of the insoluble properties of nucleic acids in alcohol. At this time, DNA is a very viscous substance, which can be taken out with a glass that can be wrapped in a clump. This method is characterized by keeping the extracted DNA in its native state. Now I'll talk about the rest, you listen slowly, if you make a mistake, please correct ......"

"No need to go on! You've got it! Lao Dou sighed and interrupted Lin Xiaowen's words, it seems that he can't help this kid, he can say what extraction methods these are, which means that he understands it.

"Yay! The teacher has passed the test again! Hee-hee! Yating clenched her fists to her chest, her face was happy, and she was very happy when she looked at Lin Xiaowen abusing Lao Dou like this.

"Then please ask a third question!" Lin Xiaowen said with a relaxed face.

At this time, no one dared to underestimate Lin Xiaowen, the randomly selected questions, this kid can tell the story, it is enough to see that this kid's medical knowledge is rich, even Lao Dou, who is unhappy with Lin Xiaowen, admires Lin Xiaowen a little in his heart, no wonder Director Li admires this kid so much, it seems that it is not groundless, and there is no purpose!

Lao Dou thought for a while, this is the last question, with this kid's knowledge reserves, I'm afraid that the way he asks questions will not be difficult for him, so won't he lose?

Thinking of this, Lao Dou's heart is a little unsettled, no, you can't lose, if you lose, you have to drill your crotch.

After thinking for a while, Lao Dou's eyes suddenly lit up, and he looked at Lin Xiaowen and said: "I can't think of this third question for the time being, when I think of it, I'll test you again, our communication will be suspended first, and we'll talk about it later haha!" Don't look at me like that, we didn't have a time limit just now, so I'm not in violation, right? ”

After speaking, Lao Dou patted his ass and sat down at his desk.

"Uh......"

Watching Lao Dou play Laipi.

Lin Xiaowen suddenly found that this guy was even more shameless than himself! Nima's, today is really a long insight.

Lao Dou said well, there is indeed no time limit just now, in this way, as long as the guy doesn't ask the third question, he won't lose, and he can't win, it seems that this old guy is planning to save this problem for the next life! My day!

"Shameless!" Yating couldn't help but look at Lao Dou with an extremely contemptuous gaze, and almost didn't go up and spit on Lao Dou's face.

"Count you ruthless!" In the face of this shameless old bean, Lin Xiaowen has no choice, he can't transform Wendou into martial arts, right?

Wen Dou, Lin Xiaowen is enough to crush Lao Dou thousands of times, if it is a martial arts fight, Lao Dou is afraid that he will have to accompany the Buddha in the West in one round.

What's more, Lin Xiaowen can't do this kind of undisciplined thing to transform Wendou into martial arts, and it also depends on the object to deal with people by force.

"Hehe, aren't you looking for Director Li? You talk, I'm going to deal with the text, I won't accompany you. The old bean laughed, and immediately tilted his head to the side.

Li Hua didn't want things to be too stiff, such an ending, everyone had a step down, so he patted Lin Xiaowen on the shoulder and changed the topic: "Are you really sure you want to join our teaching and research group?" ”

"Not sure." Lin Xiaowen shook his head and said.

"Why?" Li Hua's face changed.

"Because I have conditions, if I can't meet my conditions, I won't join!" Lin Xiaowen said.

If this was said before, the people present would definitely scoff, but now everyone doesn't see it that way, this kid is so dragged, coupled with the attitude of Dr. Li Hua, an arrogant person, to him, you can understand what this kid said, he is indeed proud of his capital and has the qualifications to say this.

"Tell me, what's the condition?" Li Hua frowned, and asked suspiciously, the other members of the teaching and research group, including Lao Dou, all pricked up their ears, wanting to hear how shocking the conditions proposed by this kid were.
