Chapter 739 Text, Code, Base Sequence

A person's life is short, but a life population can last forever.

It is unimaginable to record information in a genetic fragment of an organism.

"These base sequences should be written down by humans, and there should be nothing wrong with it." Fang Yuan observed the meteorite microorganisms in the glass ball with his supernatural power, and there were waves in his heart.

"Aren't bases a series of molecules? How can you be sure that they are artificially written and not formed naturally." Niu Dazhi turned his head and began to think seriously about this serious question.

"Ignorance really limits your imagination." Eve shook her head and sighed, with a look of resentment.

"I'm thinking seriously, can you not interfere with my thinking?" Niu Dazhi glared at her with bull's eyes.

"Let me ask you, how many Chinese characters are there in total?" Eve changed the subject and started to get to the point.

Niu Dazhi shook his head, and replied with a matter-of-fact expression: "Who will remember this stuff if they have nothing to do?"

"I will. My Chinese teacher taught it before. You have been using Chinese as your mother tongue since you were a child, and you didn't even know it." Eve stared annoyed.

"It's impossible for a normal person to know." Niu Dazhi confronted her.

"Youwei tell him quickly." Eve began to ask Han Youwei to help.

""Ci Hai" contains 14,872 Chinese characters, "Kangxi Dictionary" contains 47,035 Chinese characters, and the "Xinhua Dictionary" we usually use contains 8,500 Chinese characters." Han Youwei reported a series of data.

Eve glared at Niu Dazhi, looking very proud.

Niu Dazhi waved his hand and commented directly: "She is not a normal person, so it doesn't count."

After a while, he remembered the topic he just said, and came back again: "No. Don't change the subject. What I wanted to talk about was how do I know that the bases in the gene sequence are artificially arranged? Maybe they are formed naturally. Woolen cloth."

Eve turned her face away with a look of contempt, and snorted, "Youwei, tell him that I don't want to talk to this guy."

"Say it yourself, why do you always ask me to talk." Han Youwei muttered.

Eve was under the table, pulling Han Youwei's fingers with her hand,

He urged in a low voice: "Say it, say it, say it quickly."

Han Youwei shook her head helplessly, organized her words, and began to explain: "Okay. According to my understanding, if DNA sequences are used as codes to record information, then it should be a quaternary code.

"Our computers use binary codes. Mathematically speaking, quaternary codes can record twice as much information as binary codes.

"Binary requires four digits to record information, and quaternary only needs two digits to complete it.

"The two-fold gap is actually not that big, so if you use the genetic sequence of a living thing to record information, then the encoding method used should not make much difference.

"Meteorite civilization, let's temporarily call this civilization that records information in microbial gene sequences as meteorite civilization.

"The meteorite civilization certainly does not use Chinese characters, but no matter what kind of characters are used, the role of expressing emotions and thoughts will not change.

"That is to say, the meteorite civilization wrote their language in the quaternary code in the gene sequence of the microorganism, so we can use our language characteristics to make some speculations about the text code of the meteorite civilization.

"Everyone understands computers, so you should know that a Chinese character occupies two bytes. And one byte, converted into binary code, is actually 8 digits.

"That is to say, in our computer code, a Chinese character needs 16 binary digits to represent.

"We have tens of thousands of Chinese characters, but in fact, 1,000 commonly used characters cover 92% of written materials, and the remaining tens of thousands of rare characters are rarely used.

"These rare characters are not usually used, but it is necessary to reserve a place for these rare characters in the code.

"This has led to these codes representing rare characters, which rarely appear, and the 1,000 commonly used characters will appear repeatedly.

"I don't know what the writing of the meteorite civilization looks like, but writing and language should have similar characteristics.

"These characteristics will affect the arrangement of base codes. When certain code fragments appear repeatedly, they conform to the characteristics of text codes. It may be the text left by the meteorite civilization."

Niu Dazhi was stunned by the words: "Why do I know every word you say, but I can't understand it at all together."

"It's fine if you don't understand. You just need to feel that it sounds powerful." Eve was very satisfied with this.

Niu Dazhi seemed to be unable to find a reason to refute, so he leaned over to Fang Yuan and asked, "Did you see anything left by the meteorite civilization? What did they say?"

Fang Yuan was a little speechless, put down the glass ball in his hand, and said: "If I can see the content left by the meteorite civilization at a few glances, it must be the meteorite civilization that passed through.

"Even if this thing is known to be a text message left by the meteorite civilization, it needs a supercomputer to decipher it."

...

It was already midnight when they returned to Donghai.

Originally, I wanted to go straight to the Institute of Biology and report the fact that there was text information hidden in the genes of meteorite microorganisms.

However, no one was at work in the biological research institute in the middle of the night, so they had to go home separately.

When I got home, it was already ten o'clock in the evening.

Fang Xiaozhu has been driven back to sleep.

Fang Zhenguo was still watching TV in the living room, and the sound of the TV was turned on very low.

"I'm back, the kitchen left some food for you, do you want to eat?" Fang Zhenguo asked without turning his head, his eyes were fixed on the TV.

"I came back after eating." Fang Yuan put on his slippers and lay down on the sofa next to him. stretch.

"What did you say in tonight's report?" Fang Zhenguo turned his head and asked.

"The main thing is to talk about the crisis facing the earth and the challenges facing mankind. The purpose is to encourage students to study hard, make progress every day, protect the earth, and fight for the future of mankind." Fang Yuan replied.

"Have you gained anything?" Fang Zhenguo continued to ask.

"good."

Fang Yuan replied, stayed quiet for a while, then sat up straight suddenly, and said: "Old Fang, don't say I don't take care of you, I have made a shocking discovery, why don't I report it to you. Let you get a chance to make meritorious deeds, otherwise you will die." My rank surpassed yours in two days, how embarrassing."

When Fang Zhenguo heard this, his face darkened immediately, and he said seriously: "If there are important matters to be reported, follow the formal procedures and be serious!"

Rage point +20.

"The genetic sequence of meteorite microorganisms hides the text information left by that civilization. After finishing speaking, I will go to the Institute of Biology tomorrow. You can report to the headquarters. I will go to bed first." Fang Yuan got up after speaking, yawned room to go.

After hearing this, Fang Zhenguo's eyes widened. He was stunned for three seconds, then quickly jumped up, put on his military jacket, and walked out quickly.
