Chapter 732: A Discovery That Changed History (2)
raised his head, closed his eyes vigorously, and then Hua Xiaoru looked over again.
That's right, in that device, the 700 million and 91 base pairs of DNA it calculated, there were fragments of human genes.
Wrong, right? When did one of us get in our genes?
After thinking about it, Hua Xiaoru did not ignore this discovery, and she decided to re-analyze it.
After changing a sample, Hua Xiaoru restarted the instrument, and she only chose the genetic analysis function.
Genes, in any highly developed human society, everyone has long discovered its importance.
Genes (genetic factors) are the main substances of genetic variation. Genes support the basic structure and performance of life. It stores all the information about the race, blood type, gestation, growth, and apoptosis of life.
The interdependence of environment and heredity deduces important physiological processes such as life reproduction, cell division, and protein synthesis. All life phenomena such as the birth, growth, disease, aging, and death of an organism are related to genes.
It is also an intrinsic factor that determines the health of life. Thus, genes have dual properties: materiality (the way of being) and informationality (fundamental properties).
On our planet, as early as the 60s of the 19th century, the geneticist Mendel put forward the idea that the traits of organisms are controlled by genetic factors, but this is only a logical reasoning.
In the early 20th century, geneticist Morgan realized that genes exist on chromosomes and are arranged linearly on chromosomes through genetic experiments in fruit flies, thus concluding that chromosomes are gene carriers.
In 1909, Danish geneticist W. Johnson Johansen (1859~1927) formally proposed the concept of "gene" in the book "Principles of Precision Genetics".
After the 50s of the 20th century, with the development of molecular genetics, especially after Watson and Crick proposed the DNA double helix structure, people further understood the nature of genes, that is, genes are DNA fragments with genetic effects.
The results also showed that each chromosome contains only 1~2 DNA molecules, and each DNA molecule has multiple genes, and each gene contains hundreds or thousands of deoxynucleotides.
Since the discovery of RNA viruses, genes exist not only in DNA, but also in RNA.
Because the order (base sequence) of the deoxyribonucleotides of different genes is different, different genes contain different genetic information.
Such an important discipline has naturally been studied on the high-tech planet for a long time, and the Great Western Kingdom is no exception.
They have solved the mystery of human genes thousands of years ago, analyzing and producing a sequence map of 3 billion DNA base pairs of human genes.
When he arrived on the moon and participated in this research work, Hua Xiaoru began to crack the mystery of the alien gene at the first time.
But the genes of the alien seem to be more complicated, and the instrument she brought has calculated two completely different answers, so the device is still working automatically, and Hua Xiaoru's focus is not on it.
But the result at hand was unexpected, it was quite easy to list the test results of the alien gene and compare it with the human gene, and the result was too unexpected.
The alien gene seems to have a self-protection device, and its sequence is constantly changing, and it has been working for nearly two months, and Hua Xiaoru only knows a rough idea. Alien genes may have six billion base pairs, more than twice as many as human genes.
"Toot", the instrument sent a message, indicating that its analysis work was complete, and Hua Xiaoru's gaze returned to the data.
A fragment of the human gene, yes, is present in the seventy-million-ninety-one base sequence of the alien gene, which has not been shown in previous studies.
It was as if she had peeled off the fog and suddenly appeared in the results of the study.
"Your Highness, come here, I may have found something here."
Hua Xiaoru suppressed her excitement, and she called Yan Yeyang over.
After listening to Hua Xiaoru's report, Yan Yeyang was stunned: Impossible, right? Two species that span the entire starry sky, how can aliens have human genes on their bodies? Is the sample contaminated?
Hua Xiaoru saw Yan Yeyang's doubts, so she added: "I tried this study twice, and I got the same answer for both samples. ”
Looking at Hua Xiaoru's serious expression, Yan Yeyang was determined. He was well aware of his attitude as a chief scientist, and she would not report to him without certainty.
This is most likely a major discovery.
Yan Yeyang carefully checked the process of the two experiments, and then compared the results of the two experiments, his heart beat faster and faster:
Hua Xiaoru is not wrong, there are indeed human fragments in the alien gene.
"Try again, let's find a new sample."
made this decision, Yan Yeyang immediately found Zhang Binhui, he hoped that Zhang Binhui would take another fresh sample, as for the reason, he did not say, he hoped to announce it to everyone after confirming the results.
Zhang Binhui did not doubt him, and in the screams of the alien, Zhang Binhui chopped off a piece of alien body with his hand, and then handed it to Yan Yeyang.
Sampling, dilution, tableting, analysis, all the work was carried out in strict accordance with the procedure, and soon the results appeared on the instrument.
Confusion, as in the previous experiments, the instrument could not accurately measure the alien gene fragments, especially the seventy million and ninety-one base sequence, it was simply invisible, and the instrument could not draw it.
"What's going on, why not?
The two of them looked at the data chart suspiciously, and this result once again made them wonder, what is going on with the alien gene? Will it change?
"Which sample did you just use?"
Hua Xiaoru pointed to the tray on the table: "That's it, I took it from the Earth Research Group, and the defective products they used." ”
The two of them suddenly realized, and looked at the other side, still in frustration.
"How did you make this defective product?" Looking at the Daxi people who rushed over, Wang Hao was a little stunned: Could it be that there is something wrong with the samples we sent over?
"We've found out a little bit that it might have something to do with your sample making, so we need to find out."
Yan Yeyang said euphemistically, and Wang Hao was immediately excited:
"Really, the samples we make can help? Unbelievable! I'm going to think, let me think, and see what exactly we've done with this sample before. ”
On the side, Du Yufeng patted Wang Hao: "What do you think?" All of our work is recorded on site, so don't you just check it? ”
The group suddenly realized, and they immediately began to look through the previous video.
