Chapter 152: Beneficial mutation

? "You ... You mean, our family is all irradiated by this meteorite, and this is sick?"
Jiang Shan asked incredulously.
"Yes, you should have heard of nuclear radiation?"
Seeing Jiang Shan nod, Zhang Wei went on to say, "Nuclear radiation is a type of radiation, mainly referring to high-energy ionizing radiation such as a-rays, β-rays, and γ-rays. These rays can be understood as released by matter Very tiny particles, they have a lot of energy and can hit other particles, and the human body can be seen as composed of cells, which are composed of various organic substances, such as DNA and so on.
The aforementioned tiny particles with energy, such as neutrons, γ and β rays, can easily cause substantial changes and destruction of DNA. The consequences will be the same as if the birds hit the plane. The cells may die as a result. There may be mutations, such as cancer.
Of course, a small dose of ionizing radiation will not cause significant damage to the body, because the body itself has a certain repair ability. However, if the dose is too high, beyond the repair capacity of various organs or tissues in the human body, it will cause local or systemic lesions. "
Looking at the blank expressions of Ren Huaiyu, Jiang Shan, and Li Cui, Zhang Wei knew that his tall scientific terminology was in vain, and people couldn't understand it.
Helpless, Zhang Wei can only change one way of saying, "Let me give an example. During World War II, the United States dropped two atomic bombs on Hiroshima and Nagasaki. After the nuclear explosion, hundreds of thousands of people were killed and injured in an instant. With strong nuclear radiation, if the human body is exposed to large doses of nuclear radiation for a long period of time, it will damage the cells and organs and damage the DNA structure of the human body. The probability of the human body suffering from cancer, leukemia and other diseases is greatly increased. The survivors of Saki suffered from radiation sequelae such as cancer, leukemia and skin burns.
The situation of your family is a bit similar to what I said above. This meteorite is the source of radiation, which has been emitting radiation to the outside, and should be ionizing radiation with a great degree of harm to the human body. Your family is exposed to large doses of ionizing radiation for a long time, and a large number of cells in the body have mutated, so they will be comatose, suffering from cancer and peeling. "
Jiang Shan heard the words and smiled bitterly. He couldn't think of it. The culprit turned out to be an inconspicuous stone. He did not know that there are many examples like him. For example, on January 5, 1996, an employee of a construction company in Jilin named Song Xuewen found a small white metal chain similar to a key chain at the vinyl construction site. The tragedy happened because he picked up the nuclear radioactive material iridium-192. A few hours later, he was unconscious because of the high dose of nuclear radiation. After rescue, he survived, but he underwent 7 major operations in the next two years, and his left forearm and right leg were amputated. Left leg, and lost fertility. This is what makes nuclear radiation scary!
Li Cui hurriedly scolded the room where the meteorite was located. She was going to smash the meteorite and "revenge" for her family!
Zhang Wei hurriedly stopped Li Cui and said, "Auntie Li, that meteorite is still useful to me, so you can leave it to me."
Since getting the system of great inventors, he has been very interested in various alien objects, and this meteorite is also extraordinary, which is worth his research.
Li Cui naturally has no opinion. Zhang Wei is the only expectation of their family now. However, she is still complaining about her dead ghost husband. She has brought such a devil stone that harms the whole family to her home.
Zhang Wei ordered Beidou to arrange a flying car. He was going to take the Jiangshan family to the scientific research building. Using the equipment in the scientific research building, they carried out a comprehensive inspection of the Jiangshan family to analyze the human body caused by the radiation of this meteorite. What subtle changes have made him more aware of human genes. In other words, he has regarded the Jiangshan family as an experimental specimen. Of course, after the analysis, he will try his best to help Jiang Shan's family recover.
A few dozen minutes later, a flying car landed in the courtyard of Jiang Shan's house, and then an intelligent robot opened the door of the car and walked down.
At Zhang Wei's command, 01 put the meteorite into a box made of organic radiation-proof materials, and then arranged for the Jiangshan family to sit in a flying car and fly to the future technology company.
Zhang Wei and Ren Huaiyu also drove the steel suit and embarked on their return journey.
After returning to the scientific research building, Zhang Wei took off his steel armor, and then ordered Beidou to arrange for the robot to take Jiang Shan and his family for a comprehensive inspection, and then instructed 01 to send the meteorite to a laboratory on the fourth floor underground for preliminary According to analysis, this laboratory has done high-level radiation treatment, which can confine the meteorite radiation in the laboratory without harming the outside world.
"The inspection time is quite long, let's watch a movie together."
After Zhang Wei made arrangements, he took Ren Huaiyu's hand and didn't wait for Ren Huaiyu to answer. He ordered Beidou, "Beidou, turn on the holographic imaging system, play ..."
He turned to Ren Huaiyu, "What movie do you want to watch?"
"Avatar 2, released last year, I haven't seen it yet."
Ren Huaiyu said.
As soon as Ren Huaiyu's voice fell, the virtual screen in the air began to play "Avatar 2". It is worth mentioning that after "Avatar 2" was released last Christmas, it set a new box office record again.
After the movie was played, Zhang Wei and Ren Huaiyu had dinner together and waited for a while before the inspection results came out.
Beidou said, "Sir, the preliminary analysis results of the meteorite have come out. The shell of the meteorite is composed of an unknown substance, which is three times stronger than diamond, and twice as hard as diamond. Inside the meteorite, there is an unknown radioactive substance. , Severe radiation damage to the human body.
In addition, the inspection results of the Jiang Shan family have also come out. Jiang Aijun, Jiang's father, suffered a series of complications due to long-term large doses of radioactive radiation, leading to coma. Jiang Cui ’s mother Li Cui also suffered from cancer due to long-term large doses of radioactive radiation.
Jiang Shan's situation is a little special. He also produced genetic mutations, but his mutations are beneficial mutations. According to the analysis, his body, especially the new skin born after the skin has fallen off, has greatly increased resistance to radiation. He Now even if the radiation of this meteorite is received for a long time, the body will not be hurt. "
"Interestingly, it turned out to be an unknown substance, and Jiang Shan had a beneficial mutation and evolved the ability to resist radiation, which is really lucky!"
Zhang Wei's eyes lit up.
Both humans and animals ~ EbookFREE.me ~ are prone to genetic mutations after being exposed to radioactive radiation. Whether gene mutations are random, beneficial, harmful or neutral mutations, depends on the changes in the mutant genes' adaptation to the environment, and human evolution has now been driven by countless beneficial mutations and natural selection, which is also the principle of the evolution of all species. However, beneficial mutations are very rare, and most genetic mutations are harmful to humans, such as various genetic diseases and fetal malformations.
Therefore, when he knew that Jiang Shan had a beneficial mutation, Zhang Wei was excited because he had a new idea, that is, to collect various beneficial mutant genes of humans all over the world and then study them carefully, which is better for him to invent. 'S genetic evolution fluid is very helpful. To his knowledge, there are many beneficial mutations. For example, Mrs. Thatcher sleeps only 4 hours a day, but she is still energetic, because she has a beneficial mutation in a gene called dec2 (also called bhlhe41).
Moreover, he can also use the radiation of this meteorite to induce gene mutations in human cells, and perhaps there will be new surprises. This technology has actually been applied. It is called radiation breeding. Scientists use various rays (such as x-rays) , Neutrons, etc.) Irradiate the seeds, plants or certain organs and tissues of crops to promote them to produce various mutations, and then select the necessary heritable and excellent mutations from them to cultivate new excellent varieties.
