Chapter 1455

The cold wind blows on the deck at night. The sea is quiet and gentle. The moon is like silver satin. The stars are diamonds that fall on the dark blue sky, glittering and shining.

They are not in the mood to enjoy such a beautiful night.

Huo Shaoheng turned his head and took a look. "Ms. song, what are Daxiong and Ozawa talking about? What's more, it's similar to that of Professor Nianzhi and professor he? "

Song Jinning walked up to him, holding the rail of the ship's side in both hands, thought for a moment, and said, "is that the phenomenon of overlapping scenery caused by the super strong magnetic field I found?"

Huo Shaoheng

The exhibition scratched his head, "seems to be right? They're saying, aren't they Professor he and Nianzhi It's also overlapped... "

so there are as like as two peas in two.

Song Jinning pulled the corners of his mouth, "they can really think."

After a pause, he moved his eyes to the sea and began to explain, "I may not have made it clear before."

"First of all, quantum mechanics is more about the phenomenon of the micro world, while the phenomenon of the macro world can not directly copy this theory mechanically."

Looking at Huo Shaoheng and the exhibition, both of them are silent. Song Jinning knows that they don't understand.

as like as two peas in the cabin, she heard Zhao Liangze and Yin Shi Xiong tell about the little girl in the submarine. She knew that the girl might be really concerned about it and was exactly the same as they once knew. Even DNA said he was not sure. ——Although the little girl's DNA has not been tested yet.

Song Jinning thought of Yin Shixiong and Zhao Liangze's impromptu remarks, and then said with a smile: "in the microscopic world described by quantum mechanics, particles can indeed appear in different places at the same time. But this is about particles, not people or things in the macro world. "

"I told them just now that the scenery in Ozawa's photos is blurry, but the overlapping phenomenon with clear boundaries is really similar to this theory."

"But in the macro world, there is another explanation for this phenomenon, which can not simply be interpreted as the same scene appearing in different places at the same time."

Huo Shaoheng was silent for a moment, "what explanation do you have?"

Song Jinning made a gesture, "if we must apply the theory of quantum mechanics to the macro world, it is Schrodinger's cat."

"When a cat is in a box, it can be both alive and dead, as the saying goes," both dead and alive. "

"But when you open the box and you find the cat, there's only one state left."

"At this time, whether it's alive or dead, there's only one state, either alive or dead, and there won't be any more cases of both dead and alive at the same time."

"Do you understand? Therefore, if you have to apply the situation of he Zhichu with that of reading, I don't think it is suitable

"What's wrong with it?" Huo Shaoheng understood some and raised a glimmer of hope in his heart.

"Because in the theory of Schrodinger's cat, from beginning to end, there is only one cat, no matter whether it is dead or alive, or both dead and alive, it occurs in one cat, and there are no two cats."

"And what you are facing now is that there are two at the beginning of he, and there may be two in your mind."

"One group has grown up, and the other group has died when they were young, and their bones have been found by you. How could it be like Schrodinger's cat?"

"What are you thinking?" Song Jinning sighed, "I don't believe they are clones, so the problem is still in their DNA."

Huo Shaoheng frowned, "but the display has tested their DNA, confirming that the one who grew up with us is indeed Gu Xiangwen's daughter."

"If the little girl in this small submarine is Gu Xiangwen's daughter and is the same as the DNA read by him, it will be the same as he Zhichu and the 16-year-old."

"Why do you say the problem is still DNA?"

Huo Shaoheng was extremely puzzled.

Song Jinning as like as two peas, "DNA of the two is exactly the same?"

Her sharp eyes turned to the display, "there are three billion base pairs in the human chromosome. Have you really compared all the base pairs? Including the order in which they are arranged? "

"How could that be possible?" Display bitter smile, "three billion base pairs, but also in accordance with the order of comparison, that is impossible!"

"So if you don't compare all the base pairs, then you can't say that their DNA is exactly the same." Song Jinning is a standard scientist, who is very strict in argument and logic.

generally speaking, as like as two peas in the mouth, it is a general category.

but as like as two peas in Song Jinning's view, if two people are exactly the same as DNA, then we need to compare each base pair to get the conclusion.

as like as two peas as like as two peas, no one can be said to be exactly the same.The display couldn't believe his ears. "Do you mean to compare all their DNA base pairs completely? Three billion base pairs? "

Song Jinning nodded and said implicitly, "I know this kind of work is very heavy, but before we find a suitable theory to guide the appraisal, we have to use exhaustive method."

Huo Shaoheng eyebrows slightly close, look to the display, "you did not use exhaustive method for comparison before?"

"Ha ha..." Chen Liegan laughed dryly, "Huo Shao, there are three billion base pairs in each person's DNA. Three billion, plus the order, do you know what it is? "

Huo Shaoheng looked at him quietly, "this is your work area, do you ask me?"

After a while, he said, "Huo Shao, it's different to use DNA to test the direct kinship and compare the whole DNA base pair sequences of two people."

"Talk to people." Huo Shaoheng raised his voice, "don't drag your biomedical terms with me."

In fact, microsteate can use his hand to measure his own DNA relationship

"The usual practice is to determine the three microsatellite DNA in each parent and father."

"As long as we can find these microsatellite DNA in children, we can be 99.999999% sure that they are biological children."

"If none of these can be found, it's 100% sure it's not a direct relationship."

Huo Shaoheng listened for a long time, digested and understood it again, and said, "you mean, there are two kinds of situations when DNA is used to measure the direct kinship."

"One is that there is an immediate relationship, and the other is that there is no immediate relationship."

"In this way, it can be very accurate to exclude the situation that the two people have no direct relationship, that is, they are not biological father son or mother son relationship."

"But it's not 100% sure if you want to determine the immediate relationship between them?"

"Yes. That's what it means The exhibition nodded to Huo Shaoheng, "when I compared the DNA of Professor He and that 16-year-old boy's skeleton, I did the same thing. These MicrosatelliteDNA as like as two peas are as like as two peas. But... "

"But what?" Huo Shaoheng's eyes are sharp.

Song Jinning understood and explained to Huo Shaoheng: "I know the meaning of the display. However, from the current situation, only a few microsatellite DNA groups are compared, which can not meet our test requirements

To put it simply, it is necessary to test three random microsatellite DNA series for direct family identification.

But to prove whether two people's DNA is exactly the same, we need to compare all their three billion base pairs.

Comparing the two figures of three billion and three billion here, one can see the workload and difficulty of the latter at a glance. Compared with the former, of course, it is an increase in geometric progression.

She turned her head and looked at the display: "so you should compare their three billion base pairs one by one in order to find out what the situation is."

Because as far as DNA itself is concerned, the gap between people is actually small.

So to really enumerate all the DNA comparisons, we need to compare three billion base pairs in the original order.

In the case of he Zhichu, Huo Shaoheng originally believed in the test of display. After listening to song Jinning, it seemed that there were other situations. He immediately looked at the display: "you have not done a comparison of the order of three billion base pairs before?"

This is today's reminder of your parents' monthly and recommended tickets. Oh ~

today is Monday, especially the recommended tickets!
