"Damn! Why did it start falling as soon as I bought it!" Li Yafei didn't have the consciousness to become a real jiu dish, and he began to fall anxiously when he saw that the stock was just bought.

He bought a stock in the film and television industry, and looked at the K-line chart with a T-word at the bottom and rose for three consecutive days, that is, the language corresponding to the K-line chart is the red three soldiers and the rocket lift-off. It is easy to indicate that the mayor of the future is twenty or thirty percent.

It's a pity that this stock seems to be deliberately flying with Chang Ya, just bought it from up 3% to down 7%, the rocket did not take off, the launch failed and fell into the Pacific Ocean, Chang Yafei was in a hurry, he lost 10% and 3,000 yuan.

Chang Yafei said anxiously: "It's over, it's over! It looks like it's going to fall to the limit, T+1 trading mode, I can't sell it today, I don't know what the situation will be tomorrow, I must sell it tomorrow!"

This is still a simulated stock speculation, Chang Yafei is anxious, if he really uses his real money to speculate in stocks, his mentality would have collapsed long ago.

As a jiu dish that has just entered the market, Chang Yafei ranked at the bottom in less than half an hour after entering the market, while those students who have not yet activated their accounts are still inexplicably ranked high.

Therefore, in the capital market, not participating is profitable.

"Hahahaha!" The students before and after Chang Yafei turned their heads to look at the excitement, "I would like to announce to you that Chang Yafei, according to his principle of the three red soldiers, will be gloriously at the bottom of the game twenty minutes after the start of the game!"

The students in the class burst into laughter.

Teacher Shishi Zhou said angrily: "Look! This is an example! Just now I have repeatedly emphasized to you that before buying stocks, don't just look at the K-line chart, you must do model analysis for the enterprise, hey, you guys!"

Mr. Zhou finally said: "Finally, I would like to remind you that there is a risk ...... entering the market."

The students collectively replied: "Be cautious in investing!"

After class, Gao Siqi waited for Xiao Ming at the door of the classroom.

The research on sewage treatment colonies has reached the most critical moment, and some technical issues still need to be discussed with Xiao Ming.

The girls majoring in finance looked at the slim Gao Siqi waiting for Xiao Ming, and the gossip came.

"Xiao Ming has a girlfriend?"

"No, I haven't heard of it!"

"We have so many girls, Xiao Ming didn't even look at any of them. ”

"Don't talk nonsense, what if the two of you are just friends. ”

"Do you believe in pure friendship between men and women?"

In the second semester of freshman year, the fast boys and girls in the class all found their other half, and the bold ones also enjoyed the night together at the express hotel outside Jiangcheng University.

In the finance major where there are more monks (females) and fewer porridge (males), although Xiao Ming has an ordinary appearance, he has already given the impression that his classmates are rich and have good grades.

Everyone vaguely knows that Xiao Ming's family is engaged in industrial sewage treatment, and he has an income of tens of millions a year.

In the final exam of last semester, Xiao Ming's grade point average ranked first in finance.

Li Lingbo of the School of Economics has put Xiao Ming on the list of financial majors to protect the research, if Xiao Ming continues to maintain this momentum, the research will be a sure thing.

Girls in finance yearn for friendship with boys, and the future may develop into love, and they are also more pragmatic. Xiang Xiaoming, a low-key and hard-working rich boy, makes many girls willing to take the initiative to get to know each other.

Xiao Ming knew the thoughts of the girls in the class, and went to the laboratory with Gao Siqi.

After two months of screening, comparison, and testing, the phagocytosis team essentially isolated the bacteria that can handle contaminants in the wastewater.

Some bacteria are able to process for aromatic hydrocarbons, some are able to treat sulfides, and some are quite interested in organic matter in sewage.

However, laboratory data show that the efficiency and ability of these bacteria to treat each other are still too weak, and there is no way to treat the sewage above Class III water, let alone domestic sewage to a drinkable level.

Gao Siqi handed the 500-page experiment report to Xiao Ming and said, "The plan you proposed is not feasible, even if we perfectly combine these bacteria into colonies, there is no way to meet your requirements." ”

Gao Siqi said: "I am not an ecological environmental protection professional, but this winter vacation I am dealing with ecological and environmental protection related knowledge. Going from sewage to drinking water is definitely not a task that can be accomplished by one or two colonies. Sewage in nature is diluted by natural water, filtered by natural substances such as vegetation and sand, treated by animals and plants, treated by microorganisms, evaporated by sunlight or leaked into the ground, etc., before it may become Class III water and Class II water, and then enter the human water supply system, be filtered and disinfected again, and finally enter our water supply network. ”

Academically, Gao Siqi will always argue with reason, she said: "It's a fantasy that you treat it with bacteria." ”

Xiao Ming smiled and didn't answer Gao Siqi's question directly, but said, "Sister Qi, in the process of classifying bacteria, will it help your gene expression experiment?"

Gao Siqi said: "Although we are doing eukaryotic gene regulation expression, we did find some strange things in the process of doing bacterial experiments this time. When some bacteria in the phagocytosis 1 colony were stimulated by the outside world to induce gene transcription, we found a weak charge shift. ”

Xiao Ming also noticed this when he saw Gao Siqi's report, he said: "In eukaryotes, the current research results are that the technical level and development stage are the main factors affecting the regulation of expression, while in prokaryotes, nutritional status and environment are the main factors. ”

Xiao Ming said: "Every cell of prokaryotes is in contact with the outside world, so environmental factors affect the expression of enzymes and thus affect transcriptional regulation, while eukaryotes are isolated from the outside world in a sense, but gene regulation will always activate specific genes in specific cells at a specific time, which is a predetermined and irreversible process." ”

Xiao Ming made a bold guess based on his own observations of phagocytosis 1 colonies: "Perhaps the gene regulation expression of prokaryotes and eukaryotes is closely related to the change of base negative charge." ”

Now I boldly answer your three questions, 1. The signal that induces gene transcription is the change of base charge; 2. The main link of gene regulation is the initiation of transcription, which is realized at the moment of base change at the gene point; 3. In eukaryotes and prokaryotes, the molecular mechanism of gene regulation at different levels is the change of base negative charge. ”

Xiao Ming said: "This is just a conjecture that the gene of tuberculosis phagocytosis 1 colony regulates the expression, you can go to the laboratory to confirm it." Now what I want is to take out the gene expression point of the sewage treatment colony and add it to the phagocytosis 1 colony. The bacterial structure and gene regulation of phagocytosis 1 colonies allow these beneficial gene fragments to be brought out to the extreme!"
