Chapter 137: Regulated expression

"I depend! I depend! Why did you start to fall as soon as you bought it!" Li Yafei didn't become a real jiu dish consciousness. When he saw the stock just bought, he began to fall anxiously.
He bought a stock in the film and television industry, watching the k-line chart has a t 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. Foreshadows that the mayor's 20-30% will be easy.
Unfortunately, this stock seems to be deliberately unable to get through with Chang Yafei. As soon as he bought it, it went down from 7 to 7. Chang Yafei was in a hurry. He lost a total of 10,000 yuan.
Chang Yafei said anxiously: "It's over! It looks like it's going to stop, t1 trading mode, I can't sell it today, I don't know what will happen tomorrow, I must sell it tomorrow!"
This is still a simulated stock market, and Chang Yafei is anxious. If he really used his real money to buy stocks, that mentality would have collapsed.
As a jiu dish that has just entered the market, Chang Yafei ranks at the bottom in less than half an hour after entering the market, and those students who have not yet activated their accounts have somehow ranked high.
So in the capital market, not participating is profitable.
"Hahahaha!" The students before and after Chang Yafei turned their heads to watch the lively, "I have announced a message to you, classmate Chang Yafei, according to his principle of the Red Three Soldiers, glorious bottom at the beginning of the game twenty minutes! "
The students in the class laughed for a while.
Practice Zhou teacher said angrily: "Look! This is an example! Just now I repeatedly emphasized to everyone that before buying stocks, don't just look at the k-line diagram, be sure to do model analysis for the enterprise, hey, you!"
Teacher Zhou finally said: "Finally remind everyone that entering the market is risky ..."
The students answered collectively: "Invest carefully!"
After class, Gao Siqi waited for Xiao Ming at the entrance of the classroom.
The research of sewage treatment colonies reached the most critical moment, and some technical issues need to be discussed with Xiao Ming.
Girls in finance majoring looked at Gao Siqi with a stature and 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, in case two or two people are just friends."
"Do you believe in pure friendship between men and women?"
In the next term, the fast boys and girls in the class found their other half, and they also enjoyed the night at the express hotel outside Jiangcheng University boldly.
In the financial profession with many monks and few porridges, although Xiao Ming has an ordinary appearance, he has already impressed his classmates with rich and good grades.
Everyone vaguely knows that Xiao Ming's family is engaged in industrial sewage treatment, and has a huge income of tens of millions of dollars a year.
In the final exam last semester, Xiao Ming's average grade was ranked first in finance.
Li Lingbo of the School of Economics has put Xiao Ming on the list of financial professional insurance research. If Xiao Ming continues to maintain this momentum, insurance research is a matter of course.
The friendship between girls in finance and their male students may develop into love in the future, and they are also more pragmatic. Xiao Ming, a low-key and hard-working rich boy, made many girls willing to approach and make friends.
Where did Xiao Ming know the thoughts of the girls in the class, she went to the laboratory with Gao Siqi.
After two months of screening, comparison and testing, the phagocytosis team basically isolated bacteria capable of treating pollutants in sewage.
Some bacteria can be treated as aromatic hydrocarbons to dissolve rings, some bacteria can handle sulfides, and some bacteria are quite interested in organic matter in sewage.
However, laboratory data show that the efficiency and ability of these bacteria to cooperate with each other is still too weak. There is no way to treat sewage above Class III water, and it is even more impossible to treat domestic sewage to a drinkable level.
Gao Siqi handed over 500 pages of experimental report to Xiao Ming and said, "The solution 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'm not doing eco-environmental protection, but this winter vacation I am dealing with the knowledge of eco-environmental protection. From sewage to drinking water is definitely not a task that can be completed by one or two colonies. Sewage passes through natural water in nature. After being diluted by natural materials such as vegetation, sand and gravel, through animal and plant circulation, microbial treatment, evaporation of sunlight or leakage to the ground, etc., it may become type iii water, type ii water, and then After entering the human water supply system, it was filtered and disinfected again before finally entering our water supply network. "
Academically, Gao Siqi will always strive for reason, she said: "It's a nightmare to treat you with bacteria."
Xiao Ming smiled and did not answer Gao Siqi's question directly, but said: "Sister Qi ~ EbookFREE.me ~ Will it help your experiments in gene expression in the process of classifying bacteria?"
Gao Siqi said: "Although we are doing gene regulation and expression of eukaryotes, we did find some strange places during the bacterial experiment. When some bacteria in the phagocytosis 1 colony were stimulated by external factors and induced gene transcription, We found a weak charge movement. "
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, and the nutritional status in prokaryotes. And the environment are the main factors. "
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. Eukaryotes are in a sense isolated from the outside world, but gene regulation is always in `` A specific gene is activated in a specific cell at a specific time, which is a predetermined and orderly irreversible process. "
Xiao Ming made a bold guess based on his observation of phagocytosis 1 colony: "Perhaps the gene regulatory expression of prokaryotes and eukaryotes is closely related to the change of negative base charge."
"Now I answer your three questions boldly: 1. The signal that induces gene transcription is a change in base charge; 2. The main link of gene regulation is the initiation of transcription, which is achieved at the moment of the base change at the gene point; , Eukaryotes and prokaryotes, the molecular mechanism of different levels of gene regulation is the change in the negative charge of bases. "
Xiao Ming said, "This is just a conjecture that the tuberculosis phagocytosis 1 colony gene regulates expression, you can go to the laboratory to confirm. Now what I want is to take out the sewage treatment colony gene expression point and add it to the phagocytosis 1 colony. The bacterial structure and gene regulation can make these beneficial gene fragments to the extreme! "
