Chapter 339 Reverse Derivation
Zhang Zhi explained: This instrument is not an instrument for genetic reconstruction, but an instrument for synthesizing genes and gene expression.
We use proteins to deduce the sequence of DNA bases in reverse, which is realized through Xinglan's control of quantum computers.
Only by knowing the base sequence of DNA can we proceed to DNA synthesis.
Li Lingqiu nodded and said, Brother Zhang, I understand.
Ding Ling is operating the quantum computer, Lin Congshan is helping Ding Ling, and they are planning the scope and direction of derivation for Xing Lan.
Zhang Zhi briefly explained to Li Lingqiu the magical function of this instrument.
This instrument consists of two parts, a genetic material synthesizer and a protein synthesizer.
It mainly simulates the DNA transcription RNA in the cell. The process by which RNA synthesizes protein.
There are catalytic enzymes required for various biological genetic activities such as DNA transcriptase.
There are also more than 30,000 ribosomes, which are places where RNA is expressed into protein.
It can not only realize the forward expression of DNA to protein.
It can also deduce RNA according to the spatial structure of protein, and deduce DNA with double helix structure according to single-stranded RNA.
Zhang Zhi pointed to this instrument and said: It was not long ago, and this is Zheng Jincheng, Lin Congshan, Ding Ling and the others leading the way, with Yan Jiliang as the assistant.
In addition, most of the experts in the company's biotechnology and chemical departments have worked hard to develop the instrument.
The main purpose is to explore the life sciences, especially the role and interrelationship of genes.
Li Lingqiu suddenly realized, and she said pleasantly: I have been studying the biosphere these days, and found that they are implementing a big project, so it is this project.
It is a pity that I did not participate in the development of this topic.
There seems to be something wrong, let's go and have a look. Zhang Zhi said to Li Lingqiu.
He saw a green light flashing on the quantum computer, which should be a sign of success in deriving DNA.
They walked aside and saw on the light curtain of the quantum computer that the device was analyzing the protein composition of the photosynthetic body.
When Ding Ling saw that Zhang knew they were coming, he said relaxedly, Through the data of protein sequencing, I used the quantum computer to make the spatial folding method of the polypeptide chain deduced by Xing Lan according to its composition.
I experimented and found that the photosynthetic body is composed of 30 polypeptide chains.
Now that its folding method and order have been deciphered, we are deducing the base order of the RNA single strand based on its polypeptide chain.
This step is not difficult, it only needs Xing Lan to go through the calculation of big data. RNA synthesizes protein through ribosomes, and three bases correspond to one amino acid.
After the RNA chain is completed, we can obtain double-helix DNA through reverse transcription mode.
Now there is gene sequencing of photosynthetic virus, as long as we find the same part of the gene obtained in the experiment, it proves that our experiment has been successful.
Li Lingqiu asked expectantly: Ding Ling, how long will it take for us to know the expression genes of photosynthesis.
When Ding Ling heard Li Lingqiu's urging tone, he himself was actually very anxious. Those who engage in biological research have seen the photosynthetic body, a strange biological structure.
He was also very excited in his heart, thinking of getting this result earlier.
Ding Ling said helplessly: It depends on Xing Lan's calculation speed. Now the experiment I should do has been completed. The rest can only be found through Xing Lan's calculations and analogies.
Li Lingqiu suddenly remembered that Xing Lan was using her idle resources to simulate the establishment of the sassol forest ecosystem.
She felt that Zhang Zhi knew Xing Lan best, so she asked Zhang Zhi, Brother Zhang, Xing Lan is simulating the sassol forest ecosystem, and she still has the ability to deduce the photosynthetic gene.
Zhang Zhi made an OK gesture, and said confidently: Xing Lan's parallel processing ability is very strong, and she uses her highest ability to do one thing, but it doesn't mean she can't handle other things.
You can rest assured that all our laboratories plus the virtual world are processing huge amounts of information all the time.
Previously, her intelligence was beyond her ability to process this information at the same time. Only a part can be split to process different information.
Now that Xing Lan has evolved, she can easily process this information.
They stood next to the instrument, waiting for Xing Lan to give the result. Discussing the future application of the photosynthetic body if it is successfully produced.
They are full of confidence, they only feel the length of time needed to do the experiment. Now all technologies have been successfully tackled, and success is doomed.
Time passed slowly, and they also deeply realized that photosynthesis can be successfully produced. It will have a huge impact on society.
Xing Lan's phantom appeared on the light curtain, she showed a disappointed and painful expression, but her fingers were shaking slightly.
She said: Excuse me, I deduced the base order of photosynthetic DNA.
But I didn't find the corresponding DNA sequence on the fund chain of photosynthetic virus.
Zhang Zhi noticed Xing Lan's strangeness, and he scolded: Xing Lan, this is when scientific research is being carried out. Stop making trouble, and tell the correct result.
Xing Lan showed a mischievous expression, and said doubtfully, How did you find out?
Seeing that Zhang Zhi ignored her, she continued: What I just said is true. It is true that there is no gene sequence corresponding to photosynthesis in the gene chain of photosynthetic virus.
Fortunately, this can't stop the smart me. At first I thought the derivation was wrong. After re-derivation, the result is still the same.
Later, I discovered that there are three unconnected gene segments in the gene chain of photosynthetic virus, and when they are combined, they are the genes of the photosynthetic body.
Xing Lan was on the light curtain, showing the genetic double helix structure of the photosynthetic body. A comparison chart with the gene chain of photosynthetic virus.
Everyone breathed a sigh of relief when they saw it. At this point in the experiment, it has basically been confirmed to be successful.
Lin Congshan looked at the two gene chains on the light curtain. He said normally: This kind of transcription is very common in the expression of biological DNA.
It's just that our current technology can only express a complete DNA strand from scratch.
It is not yet possible to express a functioning protein structure from multiple broken DNA strands, as in living organisms.
Li Lingqiu saw this DNA chain, which is a unique biological beauty and the most miraculous phenomenon in nature.
On ancient Earth, the occasional double helix structure produced by the interaction of lightning and boiling water formed the basis of living things.
She was so emotional that she couldn't help urging: Ding Ling, start this experimental instrument quickly and synthesize this DNA strand. See if it can express photosynthetic body.
Ding Ling nodded, he carefully inspected this DNA strand. He said with certainty: The length of this DNA chain is 38 million base pairs, and our equipment can completely synthesize it.
Just add to it, the beginning and the end of the universal transcriptase binding. Then construct it into a DNA circle.
If there are no mistakes in the previous experiments, he can easily express the photosynthetic body.
After Ding Ling finished speaking, he began to operate the instrument to synthesize the required DNA.
There are five small molecular materials that synthesize genetic material in this instrument. DNA and RNA have three components that are the same except one.
This is why RNA can be easily reverse transcribed into DNA.
With Ding Ling's operation, the instrument started to start. According to the given DNA sequence, start to synthesize the circular structure of the DNA gene chain with complete functions.
