My biological black technology

After thinking for a few minutes, Hou Zhijie slowly spoke.

"Just looking at this genetic map, I can only be sure of one thing, and that is that about 100,000 years ago, other higher intelligent creatures may have interacted with creatures on Earth."

"As for what this advanced intelligent creature is, what purpose it is based on, and what kind of intersection it has, there is currently no way to judge."

"However, the time period of 100,000 years ago is worthy of attention."

"According to the current consensus in the research community, the Earth experienced a mass extinction of organisms between 70,000 and 130,000 years ago, and the history of human evolution also had a clear epoch during that period."

"Now it seems that there may be deeper reasons behind that blank period in the history of human evolution." Hou Zhijie stopped talking at this point.

There is no need to speculate without facts, and your words must be well-founded. This is a necessary quality for a scientific worker.

"Genes from 100,000 years ago, mass extinction 70,000 years ago."

"What a coincidence indeed."

"Regardless of science or history, all coincidences are not accidental. They seem to be coincidences, but in fact they must have their own internal reasons."

"perhaps."

Cheng Xiang looked at the familiar double helix on the big screen, "Maybe we can find something among these genes."

With an idea in mind, Cheng Xiang immediately operated the computer and couldn't help but frowned when he saw the project file with a file size of less than 300M.

"Director Hou, can we estimate the weight of the DNA in the box?"

"Yes, based on the summary data previously transmitted by the space center, it is initially estimated that the weight of all the DNA in the box is about ten kilograms, with an error of no more than plus or minus five thousandths." Hou Zhijie answered quickly.

"Ten kilograms!" Hearing the weight, Cheng Xiang looked at the engineering documents again and frowned when he saw the 300M document.

"With a weight of ten kilograms of DNA, the genetic sequence information that needs to be collected is too huge. Not to mention the limited speed of the detection equipment, even if it can be detected, it is completely unfeasible to rely on electromagnetic waves to transmit the data from Mars to the Earth."

Cheng Xiang frowned and said.

Hou Zhijie agreed after hearing this: "The average molecular weight of base pairs after dehydration is 614. For easy calculation, it can be estimated as 600. Then the base pairs on 1 gram of DNA will be of the order of 10 to the 21st power."

"Even if we don't describe the molecular formula on the base pairs next, and only transmit the base pair tags, at the current speed of 300MB per hour, if one bit represents one base pair, it will take about 4.2 times 10 times 11 power of hours, that is about 17 billion days, nearly 50 million years."

"So, theoretically, with current technology, it is simply impossible to rely on electromagnetic waves to transmit complete data."

Cheng Xiang nodded in agreement, "This is indeed a problem. However, for the time being, we have a good idea. Let's study the information on hand first."

"See if you can see anything. If you can find something valuable, then make other plans at that time."

Hou Zhijie agreed with Cheng Xiang's view that at present, this is the only way to do it, so he continued the topic, "As far as I know, the Zhurong 4 satellite deployed by the space center in Mars synchronous orbit has a bandwidth of about 300MB per hour. Based on our For emergency tasks, if you can apply for it in one day, you should be able to reach 200MB per hour."

In Mars exploration, communication resources are always tight. It is very rare to be able to apply for 200MB per day, occupying two-thirds of the total bandwidth.

"200MB per hour, or about 2.5G per day."

Cheng Xiang nodded, "This amount of data should be enough for preliminary research."

"Let's have a short meeting first to see how to proceed."

"good!"

After a period of discussion, the meeting finally decided to allocate half of the original team to the research process of unknown genes on Mars.

After the tasks were divided, it was already three o'clock in the morning.

However, from the expressions of everyone, there was no sign of sleepiness. Everyone looked excited and solemn.

However, who should sleep? Research is a long-term task.

In a blink of an eye, it was already the next night.

The space center has already sent the data received today to the Galaxy Research Institute on time around 8 p.m.

The hard disk data is about 2G, which does not reach the estimated 2.5G. It is not that the estimate cannot be accurate, but that with current communication technology, communication can only be done tens of millions or even hundreds of millions of kilometers away.

The data link will not be stable all the time, so it is quite good to get 2G data in a day.

Since the data was received and calculated yesterday, the time is not enough for 24 hours. To have 2G data, the reason why the space center temporarily increased the hourly bandwidth allocated today is because the speed data is ahead of schedule. Otherwise, even if it is 2G Don’t even think about reaching the amount of data.

Looking back more than ten years ago, at that time, Mars synchronous orbit satellites had not yet been deployed, and Mars high-altitude relay satellites were even more unthinkable.

At that time, communication could only rely on the signal transmitting device on the ground of Mars. The transmission speed was less than 100MB per hour, and due to the rotation of the planet, it could only be transmitted for a few hours a day. Compared with that time, the situation now is much better. .

At this time, at eight o'clock in the evening, after Cheng Xiang had handled other daily tasks, he heard that the data had arrived and immediately rushed to the ninth floor underground.

When Cheng Xiang arrived, Hou Zhijie was already waiting at his seat.

"Director Cheng, the data has been delivered."

"According to our requirements, the data stored here is in 49 small boxes, including the first 200MB of gene data in boxes numbered 1-10."

"Very well, give me one."

"Then according to yesterday's arrangement, the remaining data will be distributed to each group."

"good."

Hou Zhijie was very straightforward and immediately handed the hard drive to Cheng Xiang.

Cheng Xiang took it and sat down immediately. After skillfully connecting the hard disk and passing the verification, he opened the hard disk space and immediately saw the familiar project files.

After copying the project files to the confidential computer, Cheng Xiang returned the hard drive to Hou Zhijie.

After returning the hard drive, Cheng Xiang immediately got into work, double-clicked, and the project file was quickly loaded.

The familiar double helix structure suddenly appeared before our eyes. Compared with yesterday, today's data is not only ten times larger in data volume, but more importantly, the data sent from Mars today has omitted the molecular structure. Description, sent directly as base pair tags.

Therefore, the amount of genetic data presented in front of us has increased tenfold compared to yesterday. By saving the structural description of the molecular formula of each base, the base pair capacity of this gene sequencing project document has greatly increased by hundreds of times.

Therefore, the amount of data has reached 2G, which may be too far compared to the DNA information in the entire box. However, some simple research already has certain reference value.
