- Although I didn¡¯t have high hopes of passing the assessment and winning a spot.
But failing the assessment is completely different from not even having a chance to take the assessment.
Not to mention that in front of so many people, Shen Mu, the principal, personally announced that he was deprived of his qualifications
It can be said that unless he changes school, Zuo Qionghua will have no chance to get ahead as long as he is in Tianjin.
But even if you change schools, which school would dare to accept students who have been excluded by Tianda?
Zuo Qionghua finally succeeded in committing suicide
*
Qin Sheng, who was on the other side, suddenly discovered that compared to blaming someone for nothing or beating them up, directly suppressing them with force like this seems to be more effective and relieves anger?
¡°Well, let¡¯s do it again if we get a chance.
It takes a lot of effort and time to reason with others.
Only a fool can reason with others if he can use his power to overpower others.
Qin Sheng entered the biogenetic laboratory, but did not immediately go to see Wei Zhenyun as Nie Wenze said.
It was not intentional, but as soon as he entered, he saw a large group of people surrounding Wei Zhenyun, asking questions.
There were too many people, and Qin Sheng didn¡¯t want to go over and join in the fun.
She doesn¡¯t have that much time either.
So she told Nie Wenze that she would send him the detailed arrangements in the evening, and after settling her mother, she went into the nearest laboratory alone.
The assessment rules for Tianda¡¯s four major laboratories are quite clear.
Experimenters at levels 1 to 6 correspond to laboratories with difficulty levels from 1 to 6.
Anyone who has obtained the assessment qualification can enter the assessment laboratory Of course, it is not possible to skip the assessment. You can only take the exam one level at a time in the order of one to six. Each level has two assessment opportunities. After failing twice, the assessment is over.
Within the twelve hours that the laboratory is open, you can pass the exam to whatever level you have the ability to pass.
Of course, generally everyone takes exams one level at a time and goes up. So far, there has never been a case where someone took two or three levels in a row.
After all, the experimental assessment is no different from other written tests or interviews. Before the experiment, you need to formulate an experimental plan, check the instruments, and arrange the instruments. During the process, you also have to record the data, clean the instruments, etc. After you finish, you still have to organize the data and draw conclusions. Every The steps are all time consuming.
If you are unlucky and encounter trouble, you may do an experiment for half a day, a day or even several days. If you accidentally make a mistake and the experiment fails, you will have to start over.
???????????? So it¡¯s pretty good to pass Level 1 in one go.
Some of these people had science in advance, and Qin Sheng knew that he had not deliberately watched it at this moment.
Because he had been delayed outside for a while, it was already 8:20. When Qin Sheng entered the laboratory, there were already two people inside, and they had already begun the experiment.
Qin Sheng only glanced at it and then withdrew his gaze. He picked up his experimental topic from the professor who managed the laboratory, looked at it and then started.
A first-level experiment, the name of the experiment: Extracting genomic DNA from plant tissue.
It is not particularly difficult, but Qin Sheng is not very lucky. One of the characteristics of this experiment is that it is time-consuming.
If she followed the conventional method, this experiment alone would take about half a day, so she didn¡¯t need to plan anything else, just stay here and do it slowly.
¡°Obviously, Qin Sheng doesn¡¯t have so much time.
Therefore, she directly gave up the conventional method, and after thinking of violently crushing the plant tissue, she continued according to her own method.
There is no test plan, and no data is recorded. Just grab the test tubes and other instruments you need and get started.
The management professor was stunned.
But he sighed and shook his head.
He saw the question Qin Sheng had drawn, extracting DNA from plant tissue. The first-level difficulty test in public was only moderate. As long as he could do it step by step according to what he usually learned, and be more careful, there was still hope. Passed the assessment.
¡° But like Qin Sheng forget it, he doesn¡¯t want to look at it anymore.
The management professor who didn¡¯t want to look turned his attention to the other two students who came in earlier and a student who came in after Qin Sheng.
Sometimes he nods, sometimes shakes his head, sometimes sighs.
Time passed by, and the management professor's attention was always on the other students. He didn't even notice what Qin Sheng did or when he stopped.
By the time he noticed, Qin Sheng had already?The extracted DNA was deposited in a proprietary glass dish and placed on the table in front of him.
The management professor was stunned and subconsciously looked at the time: 9:07.
He looked at the record book again and saw the time Qin Sheng entered the laboratory: eight thirty-one.
A total of thirty-six minutes have passed.
Is this done?
The management professor¡¯s first impression was that she just did a few steps to get a little precipitation and that was it. This was not DNA precipitation at all.
But when he met the girl¡¯s serious gaze, the professor paused.
Especially after Qin Sheng nodded to him and said, "Trouble, check the concentration." His heart moved again.
Without asking any questions, I picked up the glass dish and put the detection solution inside to dissolve it, and then put it directly into the concentration measuring instrument.
Generally speaking, a 5g plant tissue sample can obtain about 500¦Ìg of DNA. However, as an internationally recognized A-level laboratory, Tianda University¡¯s biological genetics laboratory naturally has much higher requirements for experimenters.
The passing standard here has been raised to 5g to obtain 530¦Ìg.
There are also those with particularly high extraction rates, such as Jin Chu. The first-level question he won was also the same. His DNA extraction weight reached 550¦Ìg, which caused quite a shock in the world at the time.
While waiting for the test results, the management professor finally couldn't help but gave a few words of warning, saying: "The most important thing in doing experiments is patience. An experiment like this that can be completed in half a day at most is considered very short." , there are some troubles every month or several months, this is the first time I have seen someone as impatient as you."
The management professor was a little funny and joked: "We have a whole day, why are we in such a hurry? Are we still thinking of finishing the experiment early and rushing home for dinner?"
After speaking, he sighed again and comforted him in advance: "But there is no time. I have two chances. Even if I fail this time, I can still"
"One more time" was still in her mouth, when she saw the girl raised her chin slightly and reminded: "The results are out."
Still too impatient.
The management professor shook his head and did not try to persuade him any more. He turned to look at the results and said, "Look, it's only 572¦Ìg. The second time in a while"
The management professor only said half of what he said.
But this time it was not Qin Sheng who interrupted him, but Qin Sheng who stopped him himself.
He looked at the display on the instrument and was completely confused: "5572?!!" (Remember the website address: www.hlnovel.com - Didn't finish reading?
