Chapter 7 Helpless Choice

Shi Lei wanted to help, but Zhou Wen refused.

He resolutely drove him away on the grounds that it was inappropriate for him to help with his own work.

Shi Lei is here, he can’t do anything.

After preparing the gel, start electrophoresis analysis.

In order to prevent mistakes, he strictly follows the operating procedures for each step. The operation with ice, temperature, time, and technique are all refined, and the Eye of True Vision is always open to prevent bacterial contamination.

After the electrophoresis machine is turned on, turn back to extract the sample and place it on the glass slide, and observe it under the electron microscope.

After observation, no suspicious virus was found in the sample tissue of the mutant aphids.

Although Zhou Wen already believes that he is not poisoned, he is not afraid of 10,000, just in case.

He still insisted on doing a blood test for himself, and the results were of course no surprises. Whether it was the electron microscope observation or the true vision, he was very healthy.

“very nice~”

Zhou Wen is very happy.

The last bit of grievance in my heart has completely disappeared.

Next, start the DNA extraction work.

Skilled Dissection white rat, bone marrow extraction, washing, weighting, centrifugation, extraction, in one go.

And the dosage of one extraction is not 4 strains, but 7 strains. This general biological life is far from impossible.

Next, start to do electron microscope observation.

In fact, in theory, there is no need to perform electron microscopic observation, because the true eye has already seen the successful DNA extraction.

However, the system did not prompt the task to be completed, indicating that the electron microscope observation this step cannot be avoided.

Stain, centrifuge, extract, pipette, add fixative to DNA, centrifuge again, and add fixative.

The function of “fixing fluid” is to fix DNA and prevent the DNA from being decomposed after centrifugation.

Finally, draw the slides and place them on the stage for electron microscope observation.

“perfect~”

When the task completion reminder sounded in his ear, Zhou Wen smiled happily and glanced at the Timer. The whole process took 2 hours. It was super fast, if Shi Lei and the others knew it, their eyes would be shocked.

Just about to open the task panel, Professor Wang Huiyao, the tutor of Sees The Head Of The Divine Dragon But Not The Tail, came in from the door.

Wang Huiyao is in his fifties, is tall, bearless white face, wears a suit and tie, and people who dont know think he is a business elite.

When I saw Zhou Wen alone in the laboratory, Wang Huiyao asked strangely: “Why are you alone? There are others?”

Zhou Wen said: “Shi Lei and Lin Jiayi They just left, and nothing else came.”

Wang Huiyao was nodded and didn’t say much.

The lack of a future for biology is an open matter. The students’ feeling that they are unwilling to waste their limited energy in a laboratory with no technical content can understand it, and it is hard to criticize anything.

His eyes circled in the laboratory, and then he was about to leave.

He came to look for Shi Lei. Since Shi Lei is not there, he has no need to stay.

But at this moment, Wang Huiyao saw the glass slide on the electron microscope stage, pointed his finger and said: “This is what you inspected?”

Zhou Wen nodded, scratching his head and said: “Yes, Professor Wang.”

Wang Huiyao did not mention that novices are strictly prohibited from operating the electron microscope, and asked: “How are you learning?”

Wang Huiyao also asked casually. Undergraduates like Zhou Wen who have just arrived in the laboratory are already very good to be able to do a good job in electrophoresis analysis. It is really difficult to expect them to do electron microscope observations.

It’s not how difficult it is to observe the electron microscope itself. It is mainly due to the previous processes, such as extraction, staining, centrifugation, etc., each step can easily lead to extraction failure.

However, what Wang Huiyao didn’t think about was that Zhou Wen pointed to the 6 DNA strains next to him and said: “I have learned almost, these all are observed by electron microscope.”

“Oh?” Wang Huiyao was a little surprised, and at the same time slightly surprised, “You did it all?”

“Yes, Professor Wang.”

Wang Huiyao looked around. I just remembered that Shi Lei and the others are not in the laboratory, “Your name is… Zhou Wen, right?”

“en.”

Wang Huiyao is slightly nodded, but still not big in his heart I believe that he brought that many undergraduate interns, and few of them can do the electron microscope observation well at the undergraduate level.

He walked to the side of the electron microscope and looked at the electron microscope first.

After confirming that the electron microscope was not damaged, he looked at the glass slide on the stage and asked: “How long did it take?”

Zhou Wen glanced at the wall clock, unconsciously It’s half past six, “Uh…about 10 hours.”

Zhou Wen deliberately said the time was long.

Wang Huiyao didn’t know that the six DNA samples were extracted from the bone marrow of the same white mouse. In his knowledge, there are at least two or more DNA samples.

In other words, in a smooth situation, a group averages 5 hours.

For an undergraduate, it is very, very good, even excellent.

Wang Huiyao sat down in front of the electron microscope, adjusted the lens and started to observe.

A few seconds later, a slightly surprised expression appeared on Wang Huiyao’s face.

The structure of the DNA on the slide can be seen clearly.

Wang Huiyao lifts the head, with a smile on his face, he praised: “you did good.”

Zhou Wen modestly said: “It’s all the team leader Shi Lei and they taught well. .”

Wang Huiyao looked at him seriously.

She is quite tall and handsome, especially with the imposing manner between her eyebrows, which is so special that she has a sense of confidence that is rare in modern young people.

Wang Huiyao stood up and patted him on the shoulder, and asked with a smile: “I remember you haven’t taken the postgraduate entrance exam. How about it, are you interested in applying for my graduate student?”

Zhou Wen’s face An awkward expression appeared on it.

If it is another major, the professor invites it face-to-face, which is really a big face.

But biology…

Domestic graduate students can also do some difficult imitation experiments and help their tutors do some very low-level things, including the Court Academecian birth. There will be no independent experiments, and graduate school is basically a waste of time.

The ugly thing is the cheap labor of the tutor.

In this regard, although foreign countries are better, but the good is limited.

Because this is caused by the biological environment.

Biology is a research science. It is not only necessary to understand all the basic knowledge of biology, but also to understand all the knowledge of the research direction before innovation.

This is too difficult, too difficult.

Seeing the expression on Zhou Wen’s face, Wang Huiyao understood what he meant and didn’t say anything. After suppressing the smile on his face, nodded left.

Although he loves talents, he is not so hot as to stick to cold P shares.

And Zhou Wen also “shh”, although embarrassed, but also helpless.

Compared to graduate school, he prefers to work in a research center or a large laboratory as an experimenter, so that he can learn more and make medicine as quickly as possible. experiment.

Standing in place, thinking about the next development for a while, Zhou Wen thought of the task and immediately called the system.

The prompt box on the attribute page is still there, [Do you want to submit the task immediately? Yes/No]

Select [Yes]

[Ding! Task completed. Now start to issue rewards… Congratulations on getting 200 subject experience and 300 points. ]

[Do you want to open the box now? Yes/No]

Seeing the words on the prompt box, Zhou Wen became excited again, and muttered: “Please God, just open for me and get it out for 1,000 yuan… or Anything worth a little money will do, I won’t pick it.”

He is really poor and almost selling blood.

Nowadays, the price is expensive. It costs 10 yuan to eat a fried rice with eggs. I dont dare to ask for takeaways because of the delivery fee.

Fruits and so on didn’t even dare to look at them. He was afraid that he would shed poor tears.

With hundreds of expectations, Zhou Wen chose [Yes]

The black lacquered wooden texture treasure chest popped out, with complicated patterns engraved on it, and the side was still An ancient key is floating.

I muttered [Open] silently in my heart

The key was inserted into the keyhole, and the box opened after rotating, and a spherical object shining with scarlet emerged.

Before he could see what it was, just like last night, a prompt box popped up.

[Congratulations, get a pure natural pollution-free apple10…]

ps: Please…
