Chapter 243: Artificial Life
May 3, 2023 will be forever engraved in the history of science and technology.
Wang Xiaoxiao, a scientist at Xinghuo Technology, has created a single-celled organism with life activity in the laboratory under the Institute of Genomics.
This is the first life synthesized by scientists, which breaks the forbidden area of life and can unearth the code hidden in the genes of life.
Zhou Yu watched Wang Xiaoxiao experiment, he was testing a single-celled organism about the size of yeast cells with purple flagella on the outside.
This is a single-celled organism artificially created by scientists named Purple Orchid, which converts carbon dioxide into starch and stores it in the body when exposed to sunlight.
It is a single-celled organism that does not exist in nature, it is an artificial life that synthesizes deoxyribonucleic acid (DNA) by scientists one base pair, one base pair.
Purple orchid algae already possess the basic characteristics of all life, which is survival and reproduction.
Through the chloroplast-like composition of the cell, the purple orchid algae absorbs the energy of sunlight and synthesizes carbon dioxide and water into starch.
It absorbs energy in a plant-like way and continues to survive.
Purple orchid algae can also complete cell self-replication and complete cell reproduction.
Zhou Yu looked at Wang Xiaoxiao, who was doing the experiment, he didn't expect Wang Xiaoxiao to be able to do this step and really make synthetic life.
Since the last century, scientists have found that the genetic material of most organisms is deoxyribonucleic acid, and scientists hope to eliminate useless genes and form the most concise life.
Their efforts have all failed, and labs can synthesize some large proteins that can graft genes from one species onto another.
But scientists can't edit DNA to the point of creating life.
The fact that laboratories can create life that does not exist in nature means that scientists have mastered the genetic code.
Only by knowing the specific role of which gene and figuring out all the functional genes can scientists freely stitch together DNA and form a life-active individual.
Scientists must understand which genes are responsible for respiration, which genes are responsible for reproduction, which genes are responsible for sensing the environment, which genes control protein expression, and the most basic life has at least tens of thousands of genes that control the complex activities of living things.
These are the important components of DNA, and without understanding the specific role of genes, it is impossible to synthesize cells that are alive.
Zhou Yu looked at the purple orchid algae, and he understood the significance of the successful synthesis of this species.
With the exception of HIV, the genetic material of all life is deoxyribonucleic acid, which is transcribed into ribonucleic acid (RNA) by means of transcription.
RNA floats from the nucleus or center of the cell into the cytoplasm, and every living cell has ribosomes except for viruses.
Ribosomes are structures that express ribonucleic acids into polypeptides, which form proteins through spatial folding.
This is where the genetic material controls the process by which proteins are formed.
Deoxyribonucleic acid is an organic compound with a complex molecular structure.
It is present in the nucleus as a component of chromosomes.
Its function is to store genetic information. The DNA molecule is huge and consists of nucleotides.
The nitrogenous bases of nucleotides are adenine, guanine, cytosine and thymine, and pentose is deoxyribose.
DNA consists of a pair of polynucleotide chains coiled around a common central axis.
The sugar-phosphate chain is on the outside of the helical structure, and the bases are facing the inside.
The two polynucleotide chains are linked by hydrogen bonds between the bases, forming a fairly stable combination
Cytosine, guanine, thymine, and adenine pair up to form DNA, which are abbreviated as "C", "G", "T", and "A" respectively.
The pairing rule is C with G, T with A, C and G are connected by 3 hydrogen bonds, and T and A are connected by 2 hydrogen bonds.
Every three base pairs on DNA are transcribed into three corresponding ribonucleic acids, which correspond to one amino acid, and the amino acids are arranged and combined differently to form proteins with diverse functions.
Zhou Yu saw that Wang Xiaoxiao stopped what he was doing, and he hurriedly asked: "Director Wang, how is this species of purple orchid algae, looking at its current activity, it has met the conditions for becoming a life."
Wang Xiaoxiao's tense expression relaxed, nodded and said: "Mr. Zhou, after our testing, purple orchid algae is indeed a kind of life, our project is successful, and the gene fragments found are real and effective."
"We humans have tens of millions of genetic fragments, but 99% of them are invalid fragments, and they do not express any of the proteins that make up the human body.
The success of our project allows us to obtain a genetic scale, effectively verify the human gene, and develop medical drugs and surgical solutions for human genes to solve the diseases caused by genetic defects in the human body.
This time, we only used 50 million base pairs to synthesize the artificial life violet algae through experimental synthesis.
This is definitely a great discovery in the history of biology, and if it weren't for the quantum simulation computing capabilities of quantum computers, we would not have been able to explore the genetic code.
Only the powerful parallel computing capabilities and quantum simulation computing capabilities of quantum computers can calculate a certain amino acid represented by every three base pairs and make the corresponding protein.
This is a very complex process, and previously supercomputers simply could not effectively calculate the process of life expression, but quantum computers can easily solve it.
I hope that the company will increase the number of quantum computers in the future, and I have calculated the DNA situation of purple algae, which has already occupied 90% of the resources of quantum computers.
If we study higher-level life again, in addition to the improvement of quantum computer capabilities, we can only use multiple quantum computers for parallel computing. ”
When Zhou Yu heard Wang Xiaoxiao's request, he immediately agreed: "The number of quantum computers should be increased, Zhang Wei and they have already designed the structure of quantum computers."
You don't need to worry about the fact that quantum computers will soon be industrially produced. ”
"I'm really worried." Wang Xiaoxiao said with some concern.
"Through the Purple Orchid Project, we have figured out the code of genes, knowing the two strands of deoxyribonucleic acid, which strand is the one that expresses the protein, and why it is dominated by this strand.
Knowing the basic composition of the area that makes up the cell membrane on the DNA, you can quickly find this region of the cell membrane on the DNA of any organism.
We know the genetic code of cells such as single-celled ribosomes, and now we can unravel the genes of the human body by simply finding the secret of cell differentiation and synergy in multicellular organisms.
The DNA of higher organisms is composed of billions of base pairs, and a huge amount of quantum computer resources is required to calculate a feasible experimental protocol. ”
Zhou Yu heard Wang Xiaoxiao's opinion, he nodded solemnly and said: "You wait for my good news, I will let other departments produce a few quantum computers as soon as possible to meet your scientific research needs."
