Chapter 315: A major breakthrough in the ability of DNA to store information

(Fantasy science fiction, don't delve into it, if I really know, I won't write it to develop it.) )

In addition to the 9-storey core building, the headquarters building is scattered next to the lake like traditional houses in the Xia Kingdom.

This design concept was proposed by Zhou Xiao.

People work for eight hours or more in a day, and the working environment is sometimes more important than the living environment.

This phenomenon is especially true in large cities such as Yanjing and Shanghai.

Many white-collar workers in Yanjing have three or four hours of commuting time every day, getting up before dawn to go to work every day, going home at night when it is dark, and going to bed when they get home. Home is just a place to sleep.

The time spent working takes up most of life.

What Zhou Xiao disgusted the most was also the partition of the office, where the employees were locked up like animals in a cage.

Therefore, many departments of the new headquarters are working in courtyard-style courtyards, and the beautiful environment also reduces the psychological pressure of employees.

The natural environment of the new science and technology zone is very good, and Zhou Xiao also wants to make use of the natural environment here, instead of artificially filling in the lake and covering the vegetation, and build a few towering reinforced concrete buildings.

"In early summer, the major subsidiaries of the origin group can work here." Zhou Xiao leaned against the window and said.

Mo Li knocked on the door and walked in, looking at the scenery outside the window.

Mo Li said: "The phased experiment has been successful, do you want to go and see it?" ”

Zhou Xiao looked at the progress bar of the task, it had been almost half a year, and the progress bar of the task had not changed.

The task is too difficult.

In the past six months, Zhou Xiao also loves the laboratory and has mastered every step of the laboratory.

He also expects that there will be breakthroughs in life science laboratories in the next few days.

"Check it out." Zhou Xiao said.

In the life sciences laboratory, the technicians are doing their work in earnest.

After seeing Zhou Xiao, everyone stopped to say hello to Zhou Xiao.

Zhou Xiao walked into the core room of the laboratory, where there were several glass containers filled with crystal balls.

The container is filled with a yellowish liquid, which is the culture medium.

Nothing seems to be visible inside except the culture medium.

But in fact, there is a strand of DNA and fragmented bases in the center of each crystal ball, but because it is so small, it is invisible to the naked eye unless a professional electron microscope is used.

In the past six months, the life science and medical laboratory has used the green silk fungus as the mother bacterium, and through continuous cultivation according to Zhou Xiao's design guidelines, the new bacteria that have been cultivated with fragile cell membranes and cell nucleus outer walls have been cultivated.

After multiple generations of cultivation, new colonies are cultivated.

The outer membrane of the cell wall is almost permeable, and in this case, the DNA material inside the cell can spill out very freely.

Laboratories refer to this new colony as information bacteria.

Eventually, all of the information bacterial DNA material overflows and survives in the macroscopic culture vessel.

The laboratory also extracted the DNA material with very high stability in accordance with the design guidelines.

According to laboratory tests, stable DNA can have a life expectancy of up to 100 years under specific culture media conditions.

"The DNA strands of humans and animals are too long and easy to break, but the DNA length of the information bacteria is very suitable for the considerable amount of data that can be stored, and theoretically, 1 g of DNA can store 1 zettabyte of information," Mo said. ”

"Terrible data!"

Next, the lab work is very difficult.

They would technically break up the DNA, leaving behind strands of DNA like dead branches and base pairs free in solution.

So how does DNA store information?

The principle is similar to the binary principle.

As we all know, DNA is composed of four nitrogenous bases, A, T, C, and G complementary pairings, and the laboratory assigns adenine (A), guanine (G), cytosine (C), and thymine (T) binary values (A and C=0, G and T=1), respectively.

Then came the key point!

The gene sequence is then synthesized by microfluidic chips so that the position of the sequence matches the relevant data set. In this way, these base pairs are encoded as a combination of 1s and 0s, and the binary language can be expressed using the sequence information of DNA.

In this way, the DNA can be stored stably and can be used for sequencing when reading.

At present, the laboratory has just reached the step of breaking the DNA chain.

The next experiments cannot be completed by the life science laboratory alone, and the joint laboratory must be activated.

At this time, all the equipment of the joint laboratory was also installed, and the personnel were also stationed.

Zhou Xiao said to Mo Li: "This time has worked hard for you, and the rest of the experiments are even more difficult." ”

Mo Li looked at the budding wildflowers outside the window and said, "If everything goes well, we will give the world the greatest surprise in the second half of the year!" ”

Zhou Xiao joked: "I'm afraid that many technology companies in South Korea and the United States will be frightened." ”

The two looked at each other and smiled.

In the afternoon, Wang Yulan called.

"The information you want Chen Ye has already collected for you, will we send it to the new science and technology zone for you?"

Zhou Xiao thought that he had been in the laboratory for more than half a year, and the whole person was going to be wasted, so he said, "I'll come to the company." ”

Wang Yulan complained: "Okay, we're waiting for you in the company, and I originally wanted to come to the new science and technology area." ”

Drive to the office in Jiangcheng University Town.

Thinking that the world's greatest technology company has not yet moved into its new headquarters, and is still renting someone else's house for office, Zhou Xiao smiled dumbly.

If you tell someone about this, they won't believe it.

In the office, Wang Yulan and Chen Ye are there.

After seeing Zhou Xiao, Chen Ye gave Zhou Xiao a resentful expression and said, "You are still willing to come to the company to take a look!" ”

Chen Ye felt that the closest he was to Zhou Xiao was the Chinese New Year the year before last, and he had dinner with Zhou Xiao's parents.

It's been two years in the blink of an eye, and she and Zhou Xiao have not made any progress at all.

Both of them are busy with work and even spend very little time together.

Chen Ye even discussed a question with Wang Yulan more than once - is Zhou Xiao a monk? Is Zhou Xiao a man? and whether Zhou Xiao is sick or not, it is not good in itself.

It stands to reason that the CEOs of many large companies are not two or three or four women, even if they are married, I have women outside.

Zhou Xiao is good.

There are no women outside, and there is not a single woman at home.

Isn't there something wrong with such a man?

Chen Ye handed the collected reports of car companies on the market to Zhou Xiao and said: "Take a look at your old man, the competition in the automotive industry in the market is very fierce now, not to mention domestic cars, and many joint venture car companies are about to go bankrupt." ”
