Reborn Nine Zero became a top student, she was doted on by her seven brothers

The status is obviously so precious, but it comes so easily. The restlessness and excitement of everyone can be seen with the naked eye!

Then, there is pride!

Also, there are so many students across the country, but not everyone can stand here!

Teacher Yiguo had already stood still on the stage. Behind him was an assistant teacher and a teenage boy. No one else knew him. Song Zhizhi didn't recognize him either. He was shocked!

It turned out to be Xiao Junze!

Xiao Junze smiled at her, and Song Zhizhi also smiled, silently giving a thumbs up beside him, 6 Ah, isn't this overseas? Why did he suddenly return to China and still show up here? Not only was he a surprise, but he was also frightened.

The most important thing is that he actually stood next to the teacher and professor, which is what ordinary people can stand!

"That's Professor Shi's student, he looks about the same age as us. He's so awesome!"

"That's not true, let alone being awesome, that's just abnormal. I heard that he got very good grades abroad. He took other people's courses for three years in one year, and he was only about one year away from starting to do experiments. Now I heard

I am doing experiments with some graduate students and doctoral seniors, so I will definitely be working with teachers and professors in the future!"

"Yes, yes, this student is different from wild students like us. He can be considered a direct disciple, hahaha, that's what the novels say!"

…

After hearing this, Song Zhizhi felt more and more that Xiao Junze's growth rate was too abnormal, but she also sincerely admired and was happy for him!

It would also be good if Xiao Junze chose biology, had good friends in the same field, and was not alone in his scientific research path!

But suddenly, Song Zhizhi remembered that in addition to being famous for biochemistry, Professor Shi was also very accomplished in physics, but he was more interested in biology.

I just don’t know which one Xiao Junze followed!

"Hello everyone, I am Shi Yiguo. This is my assistant teacher Wu Changqin. That is my student, Xiao Junze. He will also join our training camp to participate in learning, training and selection. Xiao Junze, you go down first and stand with everyone.

Together."

"Okay!" Xiao Junze turned around and stepped off the stage, standing aside.

Others are still applauding for that sentence of self-introduction!

Professor Shi waved his hand and everyone immediately fell silent.

"Hello, welcome to my training camp. The pillars of the country will be born in the center. I don't like to talk nonsense. I just said it directly. The test results and scoring rules for the lunch canteen have been released and are posted on the bulletin board outside the building.

, everyone can go and have a look after we are dismissed later.”

score!!!

These two words were like a red line being stepped on, which made everyone's hearts arouse. Immediately, many people were full of confidence. The question was so simple, it was easy to pass!

Shi Yiguo smiled and did not continue the topic, "Then let's talk about the focus of today, the experiment. The first round of knockout competition begins, with an experiment as the competition topic. As for what experiment, it will be kept secret for the time being. What we need to do now is to divide the teams and present them.

There are three hundred and two people in total, and there will be two more people in a group of four. To be fair, my student Xiao Junze will randomly select one person to form a two-person group!"

"The elimination rate is half of the people, and the grades will be recorded based on individual contributions. Do you have any opinions?" the teaching assistant teacher added.

Everyone answered in unison, "No!"

Xiao Junze is very powerful, and the person chosen may not be stronger than them. The two of them, or the four of them, are indeed about the same.

And what if you are chosen!

Everyone was full of hope. Xiao Junze stood below and looked at the whole audience. Without any surprise, he pointed at Song Zhizhi's position, "This is the seventeenth classmate in this row. Please tell me your number!"

"one!"

"two!"

…

"Seventeen!" Song Zhizhi's voice became softer and softer as she spoke. Everyone immediately looked at her with envy. The youngest short girl was actually chosen!!!

Ahhhh, why not them!

But don’t be afraid, maybe Xiao Junze won’t be able to do this experiment either!

Song Zhizhi:......

Is this really good?

Although she feels pretty good hahaha!

Soon, other people began to form groups freely, forming groups of four or four. Within half an hour, they were all registered and stood in groups again.

Then the teaching assistant teacher began to distribute the experimental questions, purpose, requirements, etc., a total of two pages!

Xiao Junze took it and immediately handed it to Song Zhizhi. Song Zhizhi took a look: Extraction of plant DNA!

It should be one of the basic biological experiments for university undergraduates. It is not difficult or easy, but if you can't pass the basic biology level, there is really no need to continue.

Then there is a blank page that needs to be recorded during the experiment. You can choose to ask the teacher for the experimental steps and methods or not. If you do, you will get points deducted, but if you don’t, you will get points!

This time, nearly half of the students chose to do it!

Song Zhizhi had seen this experiment a long time ago, so she chose not to do it. Xiao Junze said he would listen to her anyway, so he had no objection.

"Okay, from now until twelve o'clock tonight, it is your experimental time, and it is also the time when the laboratory can be used. During this period, you can come and submit reports. The laboratory is on the highest floor of this building. You can do it yourself

Let’s make preparations and look forward to everyone’s good results!”

After the teaching assistant teacher finished his instructions, he waved his hand and opened the door to the outside. While everyone was turning around, the teaching assistant teacher Wu, Professor Shi Yiguo and others quickly left through the side door, leaving only a group of students.

Other students were busy looking at the previous results. Song Zhizhi and Xiao Junze walked at the back, discussing the steps.

"The experimental items are the simplest. We just go outside and pick up some young leaves. When they see the results, we go get them first and squeeze them in later!"

Xiao Junze pulled Song Zhizhi and walked quickly to the flower bed. From a distance, he could hear the dissatisfaction, confusion, suspicion, shock, lamentation and other emotions of other students in front of the bulletin board.

The two of them picked a total of more than ten young leaves and packed them in small plastic bags before going to the bulletin board. Song Zhizhi looked directly for hers, which ranked among the top ten, exceeding her expectations!

Looking at the rules again, she understood, smiled, and quickly went to the laboratory with Xiao Junze.

Seventy or eighty groups are going on at the same time, and some are very busy...

The two arrived quickly, and indeed they occupied the spot first and gathered all the experimental equipment, including pipettes, desktop high-speed centrifuges, water-soluble pots, ceramic grinders, and centrifuge tubes.

There are also different amounts of liquid nitrogen, CTAB extraction buffer: 2% CTAB (cetyl trimethyl ammonium bromide, cetyl trimethyl ammonium bromide) and other reagents.

Song Zhizhi recalled the experimental steps she had learned, "The first step is to wash 0.5 g of plant material with double distilled water and blot it dry with filter paper. The second step is to cut the plant material into pieces of about 1 cm... 4. In 5 ml

Add extraction buffer to the centrifuge tube... Step 12, add 400 ul TE buffer to dissolve the DNA."
