The Black Technology Era of Xueba

"Damn it! Damn it! Why did it start to fall as soon as I bought it!" Li Yafei didn't have the consciousness to become a real vegetable, and he started to fall anxiously when he saw the stock as soon as he bought it.

He bought a stock in the film and television industry. Looking at the K-line chart with a T at the bottom, it rose for three consecutive days. That is, the language corresponding to the K-line chart is Red Three Soldiers and Rockets. It indicates that it will be easy for the post-mayor to be 20 to 30 percent.

It's a pity that this stock seems to be deliberately unable to get by with Chang Yafei. As soon as he bought it, it went up and down by 7. Chang Yafei was in a hurry, and he lost 10,000 yuan.

Chang Yafei said anxiously: "It's over! It looks like it's going to fall by the limit. I can't sell it today in the t1 trading mode. I don't know what will happen tomorrow. I must sell it tomorrow!"

This is still a simulation of stock trading, and Chang Yafei is impatient. If he really uses his real money to invest in stocks, his mentality will have collapsed long ago.

As a jiu dish who just entered the market, Chang Yafei ranked at the bottom in less than half an hour after entering the market, while those students who had not activated their accounts were somehow ranked at the top.

Therefore, in the capital market, no participation is profit.

"Hahahaha!" The students before and after Chang Yafei turned their heads to watch the excitement, "I will announce to everyone that Chang Yafei, according to his own Red Three Soldiers principle, will be at the bottom of the game within 20 minutes! "

The students in the class burst into laughter.

Teacher Practice Zhou said angrily: "Look! This is an example! I just emphasized to everyone that before buying stocks, don't just look at the K-line chart, you must do a model analysis for the company, hey, you guys!"

Teacher Zhou finally said: "Finally, I would like to remind everyone that entering the market is risky..."

The students collectively replied: "Investment needs to be cautious!"

After class, Gao Siqi was waiting 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 watched 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, but Xiao Ming doesn't like any of them."

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

"You believe in pure friendship between men and women?"

In the freshman year, the fast boys and girls in the class all found their other half, and the more daring ones also enjoyed the night at the Express Hotel outside Jiangcheng University.

In the finance major, where there are many monks and few porridges, Xiao Ming, although he looks ordinary, 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 last semester, Xiao Ming's GPA ranked first in the Finance major.

Li Lingbo from the School of Economics has put Xiao Ming on the list of financial professionals to be guaranteed research. If Xiao Ming continues to maintain this momentum, insurance research is a sure thing.

Girls in finance yearn for friendship with boys, which may develop into love in the future, and they are also more pragmatic. To a low-key, hard-working and rich boy like Xiang Xiao Ming, many girls are willing to take the initiative to approach and make friends.

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

After two months of screening, comparing and testing, the phagocytosis team has essentially isolated the bacteria in the sewage that can handle the pollutants.

Some bacteria can process the decyclization of aromatic hydrocarbons, some can process sulfides, and some bacteria are quite interested in organic matter in sewage.

However, laboratory data show that the colony treatment efficiency and ability of these bacteria are still too weak, and there is no way to treat the sewage to a level above Class III water, and it is even more impossible to treat the domestic sewage to a drinking level.

Gao Siqi handed the 500-page experimental 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 achieve your request. "

Gao Siqi said: "I'm not doing ecological environmental protection, but this winter vacation I have been dealing with knowledge related to ecological environmental protection. From sewage to drinking water is definitely not a task that can be completed by one or two bacterial colonies. Sewage passes through natural water in nature. After the dilution of natural substances such as vegetation, sand and gravel, the circulation of animals and plants, the treatment of microorganisms, the evaporation of sunlight or the leakage into the ground, etc., it may become Class III water, Class II water, and then Then it enters the human water supply system, is filtered, disinfected again, and finally enters our water supply network.”

Academically, Gao Siqi will always fight for reasons, she said: "It's a fantasy that you use bacteria to deal with."

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

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

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 developmental stage are the main factors affecting the expression of regulation, while in prokaryotes the nutritional status And the environment is the main factor."

Xiao Ming said: "Each 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 is always in A specific gene is activated in a specific cell at a specific time, which is a predetermined, ordered and irreversible process."

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

"Now let me answer your three questions boldly, 1. The signal that induces gene transcription is the change in base charge; 2. The main link of gene regulation is the initiation of transcription, which is realized at the moment when the base of the gene changes; , eukaryotes and prokaryotes, the molecular mechanism of gene regulation at different levels is the change of the negative charge of the base."

Xiao Ming said: "This is just a conjecture of the gene regulation expression of tuberculosis phagocytosis 1 colony. 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. Phagocytosis 1 colony The bacterial structure and gene regulation of the bacteria allow these beneficial gene segments to work to their fullest!"
