NASA astronauts stay in space for a year, do the genes really mutate7?

It's true. This is the twin program launched by NASA, and they chose a pair of twins for this experiment. NASA sent her younger brother into space, while her older brother remained on Earth.

A year later, when the younger brother returned to Earth, NASA compared the DNA of the two. It was found that the younger brother's gene was really mutated by 7% and was irreversible. But this mutation is simply a change in the expression form of the gene.

The exact impact of these changes remains to be seen.

Yes, the gene does mutate by 7%, because the radiation in the universe is still quite large.

It's not 100% certain, because everyone's individual physique is different, so everyone will cause some differences to a greater or lesser extent.

Yes, one of the American twins happened to be astronauts, and after he returned from space, he found that his physical constitution was 7 percent different from his brother's

What kind of DNA mutation producesAs a result, opinions are mixed。Some say it's the result of human adaptation to the space environment, and some say it's a damage to human life. At this time, a series of genetic mutation characteristics are thrown:

Universality, randomness, low frequency, non-directionality, more harm and less benefit. It's the same as our first feeling, which is more harm than good. For example, eating genetically modified foods is no longer advocated, and most of the attitude of human beings towards genes is awe, believing that it is Pandora's box.

If human beings carry out certain production activities and scientific research activities that lead to genetic mutations, it may lead to a counterattack by opposing forces, and everyone should not go to heaven. Why doesn't anyone say that now? Because,The truth is not as serious as it is reported, said to be a permanent DNA mutation, is actually a change in the level of reversible gene regulation.

Let's not talk about the facts, if it is true, this leads to many possible outcomes. Some people say that it is not this group of humans who go to space, but mutants who will appear in the future, after all, babies with genes are now born. Some people laughed and said that they wanted to get some longevity genes.

It is impossible to tell whether this concrete imagination of the future is right or wrong. Genetic mutations were considered long before astronauts went into space, so many astronauts go up after giving birth. Such a discovery is not new, but it has been reported this time.

At this time, the era we live in is gradually realizing the ideas in science fiction films, and this revelation has opened up all kinds of brain holes. But for real scientific and technological work, it is still carried out step by step. Will it become an obstacle to mankind's conquest of space?

This is mainly due to the strong space radiation, which induces mutations in genes. Space rays are very strong, mainly solar wind particles, because the earth is protected by the geomagnetic field, so that the solar wind particles deflect to the poles of the earth, the occurrence of the aurora phenomenon is evidence.

There is no protection from the geomagnetic field in space, and astronauts are bombarded by particles and are highly susceptible to genetic mutations. Spacesuits and capsules, which were initially less resistant to radiation, have now been greatly improved, and astronauts are much less likely to be harmed by particle radiation.

Radiation is an important way of human breeding, the use of plant seeds or radiation irradiation, genetic mutations will occur, looking for favorable mutations, and many purification selections, will breed new varieties. Therefore, DNA mutations are not always harmful, and they do not necessarily cause cancer. Excessive radiation, sickness is undoubted.

Seeing this news, we should pay more attention to protecting the earth, preventing environmental pollution, and not always wanting to migrate to Mars to live, which is unrealistic, and it is more important to protect the earth! It is necessary to live in symbiosis with other animals.

Astronauts stay in space for 340 days, and the DNA is permanently mutated", and mankind's conquest of space has encountered new obstacles? This one is definitely having an impact, and this aspect will be taken into account in the future.

Astronauts take space for 340 days, the DNA equation is permanently withdrawn mutation, and human conquest of space has a new breed, which hinders the return in 330 days.

Mainly the result of the absence of gravity in space! You'll have to invent a gravity-based system like in a science fiction movie!

The common home of mankind is the earth, which has nurtured generations of people. It is the most suitable for people to live in. Humans in space can only explore, cannot conquer, and cannot adapt to human habitation.

If humans want to conquer space, it will be very difficult. It's going to be a long, long process.

Human beings yearn for space, in fact, space is also silently waiting for human beings to conquer him to live and work in peace, so like this DNA, this hair, and bad things, I believe that in the future development of science and technology, it will definitely change.

Science and technology are constantly advancing, I believe that a lot of things that can not be solved will be solved in the future, 20 years ago, mobile phones were not popular, but now mobile phones are omnipotent. It's just that DNA mutations have the possibility of cancer, and if cancer is overcome, it will not be solved, and space needs to be explored, because it will create infinite scientific and technological wealth for human beings on earth, and the advantages outweigh the disadvantages, so we must discover and pursue progress.

This is possible because I have heard that seeds such as space peppers are genetically mutated by sunlight in space.

Human beings yearn for space, and space is also silently waiting for mankind! With the advancement of science and technology, I believe that these problems will be solved. Because the problem of DNA mutation is by no means insurmountable!

So to speak.

Human beings adapt to the earth's environment, but not to the cosmic environment.

Why isn't it the universe's law of survival for living things, genetic mutations, maybe evolution, maybe people can survive in space,

The progress of modern science and technology has led to the existing human beings not being able to measure themselves, and today's exploration of the universe violates the law of human historical development and is too advanced, just like primitive people worship the sun.

Genetic mutations are not all bad, some are an adaptation to the environment and some are an adaptation to the environment. Astronauts stay in space and are exposed to all kinds of radiation, and despite being well-equipped, high-frequency radiation waves can still penetrate spacesuits and space stations.

But there are also astronauts who suffer from some special diseases due to excessive radiation. We cannot directly say that mankind has encountered new obstacles in the conquest of space, we must understand the situation of the mutation and the causes of the mutation, and we must not draw conclusions prematurely.

I'm a science popularization assistant, and the scientific questions are left to me!

The vast knowledge of the universe is endless, and there are many unsolvable mysteries that require knowledge development.

When astronauts return from space, the genes of their bodies do change, and the length of their lifespan will also change, but the length of their lifespan is inconclusive. <>

American scientists once did a study of a twin, one of the twins has been in space, in the astronaut's 40-year study of the astronaut, they did find that after the astronaut returned from the universe, the body's genes have mutated, the length of chromosome telomeres has become longer, and chromosome changes mean that the length of a person's life will be affected. But the study did not point out how chromosomal changes played a role in longevity, or brevity, or how they were produced.

At the beginning of the study, scientists did find that the astronauts had their genes destroyed after returning from space, but six months after returning to Earth, the gene sequence returned to normal. This phenomenon has been experienced by almost every astronaut who has been on the space, and many astronauts will return to the body from the universe after long-term training, such as nasal bleeding, brain deformation, and eye compression, such pain is unbearable for us ordinary people, and only people who have undergone long-term training can do it. <>

And physical pain is not the main thing, there will be an invisible force in the universe to change the genes of the human body, but when you return to the earth, these changes will gradually disappear, but there are still some small changes, which will still remain in the human body, causing damage to the human immune system.

In fact, the universe will change to all living things, for example, after China's astronauts land in space, the capsule will bring a large number of plant seeds, these seeds follow the astronauts to drift into space, and take root and sprout after returning to the earth.

No, the length of life has nothing to do with genes. Genetic changes can only affect the physical characteristics of astronauts, not lifespan.

Astronauts are affected by space rays, so there are some changes in genes, and the length of their lifespan will also change.

Yes. The astronaut's body is exposed to space radiation, and the genes will mutate, which is very harmful to the body.

The environment of space is very different from that of Earth. Astronauts in space will undergo some kind of changes in their bodies because of the different environments. So what exactly are these changes?

After astronauts return to Earth after completing space science experiments, it is likely that a series of physical changes will occur, which may be related to contact with the space environment.

Of course not, the ISS can also be used for a while, but the environment inside can affect people.

This is impossible, because there is a possibility of electric radiation from the sun everywhere in space, and these are certain measures for genetic change, but they are all within a controllable range.

I think we should continue to conquer. Because if we don't make progress in China, it means that we are regressing, so how can the people in China be protected?

DNA mutations refer to abnormal changes in the structure, replication, or phenotypic function of individual DNMP (deoxynucleoside monophosphate) residues and fragmented DNA (also known as DNA damage). A large number of mutations are spontaneous mutations, and the causes of DNA mutations are mainly divided into physical factors, mainly ultraviolet rays and various radiation, chemical factors are mainly chemical mutagens, and biological factors, mainly viruses.

DNA mutations can be spontaneous or induced. There is no intrinsic difference between spontaneously produced gene mutations and induced gene mutations, and the action of gene mutagens only increases the mutation rate of genes. Genetic mutations can be useful or harmful to humans.

Since most mutations are harmful to living organisms and the occurrence of human cancer is closely related to genetic mutations, the detection of mutagens in the environment has become an important task for public health.

Science examined 55-year-old Scott thoroughly after he returned to Earth three years later, and found that the carotid arteries and retina thickened when left in space, according to a study in the journal. The intestinal flora increases and cognitive declines, but after six months of returning to Earth, most of the symptoms gradually disappear, but only the genes cannot be restored. Scott said that the day he returned to Earth was very uncomfortable, and that he was not tired for a long time.

The earth's resources are being depleted, and we are also looking for a second home for humanity. In the long run, it is beneficial to humanity. But exploring the unknown always comes at a cost.

We humans should continue to conquer the moon and never stop! Even if the road of exploration is difficult, it still cannot stop us humans from continuing to conquer the moon. A report of a permanent mutation in the DNA of an astronaut has attracted public attention.

After surviving on the International Space Station in outer space for 340 days, the American astronaut returned to Earth and compared the astronaut's DNA to that of his twin brother. It was found that after testing and comparison, the astronaut's DNA had been mutated and permanently damaged.

According to relevant sources, although this gene mutation is not directly dangerous to the body at present, it will lead to a higher probability of cancer in the future than ordinary people. Despite all kinds of dangers, astronauts are a ladder connecting us to the universe and a bridge for us to explore the universe. For us humans, there are too many unsolved mysteries waiting for us to discover, and we need to continue to explore.

WhileThe moon is by far the most thoroughly studied object we humans have ever studiedIt can be said that it is the first celestial body that we humans have personally visited so far, except for the earth. Since 1959, I have landed on the moon to explore, and slowly learned about the moon not only in terms of appearance, but also in terms of its age, environment, surface temperature, and so on.

What we humans want to explore is whether the moon is suitable for us to live on other than the earth. What is the environment like? What kind of future the moon will bring to mankind and so on, we or our next generation need to continue to explore.

Although there are gains and losses in the process, I believe that it still cannot stop us from searching for unsolved mysteries, no matter how difficult the journey isNone of us will give up on conquering the moon.

DNA mutations can be spontaneous or induced. There is no essential difference between spontaneously produced and induced mutations, and mutagens only increase the mutation rate of genes.
