In a cold and quiet office.

Officer Zhao was holding a brand-new newspaper in both hands, and was reading it with intent, no, it should be said that he was studying something, because he was dumbfounded, his two eyes were shining like night pearls, and the tea on his table was cold, but he didn't have time to take a sip.

The newspaper smelled of ink, as if there was some indescribable magic that had made him lose his self-control.

This is a new issue of the newspaper, and an article on "Genetic Mutation" is published in the 'Eyes of the World' section.

This article is so similar to the one he just read called "Genetic Mutation Spring Legs".

"Isn't that the same thing?"

Officer Zhao couldn't help but muttered to himself.

The original text is described below

"Genetic mutations simply refer to sudden, heritable mutations in genomic DNA molecules.

At the molecular level, a gene mutation is a structural change in the composition or order of base pairs.

Although genes are very stable and can replicate themselves precisely when cells divide, this stability is relative.

Under certain conditions, genes can also be suddenly changed from the original form of existence to another new form of existence, that is, at a locus, a new gene suddenly appears, replacing the original gene, this gene is called a mutant gene. As a result, new traits suddenly appear in the performance of the offspring that the ancestors never had.

The genetic mutation was first identified in Drosophila by th Morgan in 1910.

HJ Mahler in 1927 and LJ Stadler in 1928 used X-rays to induce mutations in fruit flies and corn, respectively.

In 1947, Aerbach used a chemical mutagen for the first time, inducing mutations in fruit flies with nitrogen mustard.

In 1943, Se Luria and Delbrück were the first to demonstrate in E. coli that the emergence of resistance to bacteriophages was the result of genetic mutations. The same conclusions were then reached on bacterial resistance to streptomycin and sulfonamides.

The characteristics of genetic mutations, whether they are eukaryotic or prokaryotic mutations, and no matter what type of mutation, all have common characteristics such as randomness, low frequency, and reversibility.

They are universality, randomness, rarity, reversibility, less benefit and more harm, non-directional, beneficial, and so on.

In particular, it is beneficial, which is the only way for plants and animals to evolve to a higher level.

For example, a bird has a short beak, and when its genome suddenly mutates, its beak becomes longer, so it can easily catch food or drink water.

For some people, after the genetic mutation, their body will be significantly different from normal people, such as a special ability, a certain aspect of talent in the mind, or some physical quality, etc., and so on, higher than normal people's abilities.

This is reflected in the abnormal sense of hearing of people with genetic mutations, just like bats or dolphins, whose ears can catch ultrasound waves that ordinary people cannot hear, judge the size and location of the sound source, and then carry out a series of positioning activities.

It is also reflected in the tactile sense of the gene mutant, for example, the genome that controls the tactile nerve has been mutated, so his skin will not be afraid of cold like a cold animal such as a snake and worm, even in the Arctic region, which is freezing in the sky, and he will not feel cold bare-chested; For example, some genetic mutants, such as flies and mosquitoes, can sense the invasion of foreign bodies from a distance, and their skin is like the tentacles on some small animals, which can keenly sense and distinguish foreign bodies before they have been touched.

It is also reflected in the smell of genetic mutants, such as having a canine-like sense of smell, which is at least 1 million times higher than that of ordinary humans, and then, through the sense of smell to do all kinds of things.

For example, finding people by smell; By smelling the change in the smell of sweat on people, you can identify people with diabetes or hypoglycemia in your family; Through the sense of smell and the perception of geomagnetic changes, it is possible to predict natural disasters such as earthquakes and storms.

It is also reflected in the vision of genetically mutated people, such as the sharp eye of an eagle, which is 6 to 8 times the vision of an ordinary human.

It is also reflected in the taste sense of people with genetic mutations, such as catfish, which has a staggering number of 100,000 taste bud cells, while normal humans do not exceed 20,000 at most. Such people are like wolves catching a scent, and can catch the smell of different animals and plants from afar.

In short, in addition to this, of course, it is reflected in other aspects.

For example, a type of genome that can control the speed of cell division can be used to live a long life, and even immortality is possible.

For example, a group of people who control the gene cell group that controls bone development, through which they can make their bodies grow like crazy, and then use their height advantage to enter the NBA to play basketball, or participate in other sports or sports about height advantage.

Everything has a cause.

Generally speaking, there are two possible circumstances that can lead to such genetic mutations.

1. In the process of DNA replication, the number, sequence, and type of deoxynucleotides inside the gene are locally changed, which changes the genetic information and affects the external characteristics.

2. External factors include physical, chemical and biological factors; Among them, physical factors include X-rays, lasers, ultraviolet rays, gamma rays, etc.; Chemical factors include nitrous acid, aflatoxin, base analogues, etc.; Biological factors are certain viruses or bacteria, etc.

”

When Officer Zhao read about the main factors affecting genetic mutations in one breath, he suddenly patted his head as if he remembered, thinking that the topic of genetic mutations was also mentioned in the last issue of the newspaper.

"Global Warming"

"Epidemic infectious diseases"

"Radioactive microorganisms under the ocean"

"That's right," Officer Zhao suddenly thought of those memory fragments that had just stayed in his brain for a short time, and immediately became energetic, "Causing a genetic mutation!" ”

So he quickly grabbed the postponed newspaper that he had stuffed into the newspaper column and read it again.

"As a result of global warming, a small proportion of flora and fauna in the Indo-Malayan rainforest biome, the African rainforest biome and the American rainforest biome are mutating.

According to relevant media reports, there is a green plant called 'emaciated grass' in Indo, which looks quite like pothos, and as the global temperature rises, the genome of the cells inside the plant gradually begins to mutate, and eventually the grass will secrete a hormone that can dissolve fat, and once obese people take it, the body will gradually lose weight. As a result, some people use it as a good medicine for weight loss.

Due to the rise in global temperature, the mutated grass, there is also a kind of drunken grass, distributed in South America and other countries, it can secrete a chemical agent called strong naphtha oil, once people smell it, they will immediately get drunk and fall to the ground, and they can't stand up for a long time, the leaves of this grass are cross-petaled, and the leaves grow many white powder particles.

There is also a kind of salt grass, that is, a grass that secretes salt, which is distributed in the eastern part of China, and its appearance is similar to that of rose grass.

There is also a mimosa, which is found in many parts of Asia, and it has a very complex nervous system, and when a leaf is touched, the entire mimosa leaf will immediately roll up. Scientists have discovered that this reaction is not a simple chemical reaction, but a reaction based on electrical impulses.

There is also a longevity grass, which is found in the hilly areas of northern Nigeria, Africa, and is known locally as longevity grass, or happiness grass. This grass is evergreen all year round and grows a stem node every year; The height of the 100-year-old grass can reach 15~16 meters.

There is also a luminous grass found in the Nanspuncao grasslands of The Gambia, Africa, where the crystalline on the outside of the leaf lobes shines at night, and it is said that the locals transplant it to their yards to serve as 'street lights' for illumination.

There are also 'wind weeds', 'flytraps', 'rice grasses', etc., which are almost all the result of mutations in the genome of cells in the body after the temperature rises sharply.

”

"Oh my God!" Officer Zhao read and read, and suddenly, he felt creepy.

"In addition to the plant kingdom, the animal kingdom is no exception.

According to the prediction of relevant experts, in the near future, as the global temperature continues to rise, there may be many examples of genetic mutations in the animal kingdom, at that time, just like the science fiction movie, the mouse may mutate to the size of an elephant, and the elephant may mutate a pair of wings and fly into the sky like a bird.

It is also possible for a tiger to mutate a pair of wings and fly into the sky to hunt herbivores.

Of course, humans are no exception.

Epidemic infectious diseases can also cause genetic mutations in some plants and animals.

According to relevant media reports, a young boy in the United States almost died of the flu virus, and scientists found a rare genetic mutation in his body, which caused his immunity to weaken, and once the flu virus invaded, it would cause a serious illness.

Microorganisms underneath the ocean can also cause genetic mutations.

In the journal "Science" in the United States, there was an article called "Genetic Mutation Caused by Waste Batteries", the principle of which is that waste batteries are not effectively recycled by humans, and then lost in the garbage dump, and people do not have the awareness of garbage classification, which leads to some garbage into the ocean and sinks to the bottom of the sea, and the harmful elements such as lead, mercury, nickel, and cadmium in these batteries are absorbed by microorganisms on the seabed, which then leads to their genetic mutations.

As these microorganisms grow in size, they also act like batteries, emitting a harmful substance from their cells, causing a cascade of genetic mutations in plants and animals around the ocean, which ultimately affects humans. ”

Finally, driven by curiosity, Officer Zhao finished reading what he thought was boring news in one go.

After reading it, he put his hands on the edge of the table, and his mood could not be calmed for a long time.

"Could it be," Officer Zhao's brain reacted extremely quickly, as if he had also mutated his genes, "So, that spring-legged Mark Payne, is it the result of genetic mutations?" ”

Although the newspaper did not give a clear answer, Officer Zhao basically had a bottom line in his mind at this moment, "Most of this is related to genetic mutations." ”

Mark Payne was born in the slums of Florida, and there was a news report in his city that a plant called chameleon had a genetic mutation, but the news was not believed at the time, and people thought that the newspaper's behavior was a shameful act to attract people's attention and arouse curiosity, which completely violated the principle of truthfulness in the news industry and ignored its own professional ethics.

So the news went down later.

"Isn't that so? Genetic mutations are universal, that is, they can mutate in the genes of animals and plants, no matter where, at what time, or even under what circumstances. Officer Zhao came to such a conclusion in his heart.

However, Officer Zhao thought of the rarity of genetic mutations, that is, the probability of genetic mutations occurring is very small, and in this way, the small one is like winning a million welfare lottery.

"Even then, it doesn't necessarily mean that the genetic mutation won't occur, just in case," Officer Zhao guessed to himself

"What if it's stimulated by something? Isn't there an internal, external, and biological factor for genetic mutations?

In case Mark Payne accidentally comes into contact with some rays, or accidentally swallows a large amount of aflatoxin, which can cause cancer, while eating, isn't it the result of a genetic mutation? What about the fact that it has become a special function of other beneficial properties?

Or maybe it's not impossible to be attacked by some virus, etc.! ”

In this way, after reading the newspaper, Officer Zhao speculated in his brain for a while, and then he was busy looking for answers in this issue of the newspaper.

Officer Zhao checked it several times in a row, and there was no follow-up to the article about "Gene Mutant Spring Legs" in the remaining newspapers.

"Do you have to wait for the next issue?" Officer Zhao looked unhappy.

At this time, he had almost forgotten the 'unsheep phenomenon' that had been bothering him.
