A large group of people entered the forest in a mighty manner. This time, there were so many of them, and they had advanced weapons and well-equipped equipment! If you don’t believe it, can they be wiped out again?
The large army walked in cautiously, but they still subconsciously divided into small groups. After all, they came from different countries.
While walking, Qin Hao suddenly stopped: "Stop!~"
Those Americans stopped. When other people saw the Americans stopping, they also stopped. Alas! What a sad herd effect!
Qin Hao said: "Did you hear it? There is a sound..."
The captain of the American special operations team shook his head: "Nothing? Sir, what did you hear?"
Qin Hao squinted his eyes: "Listen carefully...can't you hear it?"
They indeed couldn't hear anything. Qin Hao understood that the ears of these guys were indeed not very good. He simply stopped forcing them. Qin Hao continued: "You all listen to my command! Now... everyone
Find a place to squat or lie down, and don’t move..."
The Americans were all lying on the ground. People from other countries didn't know what was happening. Suddenly, countless vines fell from the sky. These vines began to grab some people's bodies and began to pull them upward. Their power was very strong.
It's so big that it can even tear off a person's arm.
Everyone roared, and some screamed in fear. After a group of vines attacked, the large army lost more than twenty people, and then there was a roar like a wild beast.
Qin Hao shouted again: "Hidden! Be careful...that thing is coming down!"
Waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaged by the people, and everyone shot crazily at that thing. So many guns hit it finally had some effect, that monster was shot by so many
The gun fired wildly, and my body gradually couldn't bear it anymore.
But at this moment, the other two Dark Guardians came down. One of them grabbed a special soldier and pulled hard with both hands. Hiss... the body was torn into two halves, and someone started throwing grenades at them.
The power of the grenade is obviously different. The impact of this thing is incomparable to that of bullets. After a loud noise, a big monster was blown away, and its body fell back for more than ten meters.
Far.
After falling to the ground, his body twitched twice, and the next scene, which surprised everyone... happened.
The dark guardian who originally looked like a monster actually began to shrink after he died. Gradually, his height gradually changed from four to five meters to more than three meters, more than two meters, more than one meter, and less than one meter tall.
Meters, less than half a meter...
In the end, it turned into a little monkey that is only more than 20 centimeters tall. What is going on? This does not follow the law of conservation of mass at all!
Qin Hao was also stunned: "Damn it! What's going on? I'm not in a fairy tale, am I?"
Some people discovered that there were grenades that could blow up this thing, so they took out the grenades and threw them at the big monsters. Soon, more than ten big monsters that looked like gibbons were killed or seriously injured by the explosion.
.
They lie on the ground. After they are completely dead, their bodies will become smaller, and all of them will become smaller without exception. They are just ordinary little monkeys. The faces of these little monkeys look a bit like baboons.
A little painted face.
Wow... Qin Hao opened the microcomputer on his wrist and received a long email. After Qin Hao opened the email, through the wireless headset, the computer began to transmit it...
Genes (genetic factors) are the material basis of heredity and are specific nucleotide sequences with genetic information on DNA or RNA molecules. Genes pass genetic information to the next generation through replication, allowing the offspring to have traits similar to their parents. Humans have approximately
Tens of thousands of genes, storing the pregnancy of life
All information on the processes of reproduction, growth, and apoptosis can be completed through replication, expression, and repair to complete important physiological processes such as life reproduction, cell division, and protein synthesis. All life phenomena such as the growth, growth, disease, old age, and death of organisms are related to
Gene related. It is also an intrinsic factor that determines human health.
In 1932, H.J. Mahler classified genes into null genes, sub-effect genes, super-effect genes, neo-effect genes and anti-effect genes based on the relationship between mutant genes and wild-type alleles.
The expression of gene effects is inseparable from the influence of the internal and external environment. Among a group of individuals with a specific gene, the percentage of individuals that express the trait of the gene is called penetrance; when a group of individuals with a specific gene express the trait
Among individuals, the degree of expression of a trait is called expressivity. Both penetrance and expressivity are affected by the internal environment and the external environment.
Qin Hao muttered: "What kind of crap are these?"
And then, finally we get to the more important things...
Genetic variation refers to sudden heritable changes in genomic DNA molecules. From a molecular level, genetic variation refers to changes in the base pair composition or arrangement of genes in their structure. Although genes are very stable, they can survive cell division.
It can copy itself accurately every time, but this stability is relative. Under certain conditions, genes can also copy themselves from
The original form of existence suddenly changes into another new form of existence, that is, a new gene suddenly appears at a site, replacing the original gene. This gene is called a mutant gene. As a result, the performance of future generations also suddenly changes.
New traits appear that have never been seen in ancestors. For example, Queen Victoria’s family had not discovered hemophilia before.
patient, but one of her sons suffered from hemophilia, becoming the first member of her family to suffer from hemophilia. Later, several more hemophilia patients appeared among her grandchildren. Obviously, in her
A mutation in the hemophilia gene occurred in one of her father or mother. The mutated gene was passed to her, and she was heterozygous, so her phenotype was still normal.
But it was passed on to her son through her. In addition to the genetic diseases caused by the formation of disease-causing genes as mentioned above, the consequences of genetic mutations can also cause stillbirth, spontaneous abortion and postnatal death, etc., which are called lethal mutations; of course, they can also cause
It has no effect on the human body and only causes genetic differences between normal human bodies; it may even bring certain benefits to the survival of the individual.
In the past, the "Human Genome Project" involving scientists from many countries tried to draw a complete arrangement of human chromosomes at the beginning of the 21st century. As we all know, chromosomes are the carriers of DNA, and genes are fragments of DNA that have genetic effects and constitute the basic unit of DNA.
There are four kinds of bases. Since each person has 3 billion base pairs, deciphering the base sequence of all DNA is undoubtedly a huge project. Compared with traditional gene sequence determination technology, gene chips are more effective in deciphering the human genome and detecting gene mutations.
It's thousands of times faster.
The main reason why the detection speed of gene chip is so fast is that there are thousands of microgels on the gene chip, which can be detected in parallel; at the same time, because the microgel is three-dimensional, it is equivalent to providing a three-dimensional detection
Platform, capable of immobilizing proteins and DNA for analysis.
The United States is conducting research on gene chips and has developed a "gene chip" that can quickly decipher genetic codes, making the speed of deciphering human genes 1,000 times faster than currently.
Genetic recombination is a process in which DNA fragments are exchanged and recombined due to the breakage and connection of different DNA chains to form new DNA molecules. In 1974, Poland's W Szybalski called genetic recombination synthetic biology. In 1978
He wrote in the journal Gene: Restriction enzymes will lead us into a new era of synthetic biology.
…
After listening briefly, Qin Hao understood what the other party meant. The creatures here were probably caused by genetic mutations.
The so-called gene mutation refers to the sudden and heritable mutation of the genomic DNA molecule. From a molecular level, gene mutation refers to the change in the base pair composition or arrangement of the gene in its structure. Although the gene is very stable
, can accurately replicate itself as cells divide, but this stability is
On the contrary, under certain conditions, genes can suddenly change from their original form of existence to another new form of existence. That is, a new gene suddenly appears at a site, replacing the original gene. This gene is called
Mutated genes. As a result, new traits that the ancestors never had suddenly appear in the performance of offspring.
In the past, genetic mutation should be a very long event, but in fact, under the influence of some extremely strong external forces, some extremely fast physical mutations may occur!
Nuclear radiation can cause some organisms to mutate, but its force has not reached such a strong point of action. A powerful external force that is more terrifying than nuclear radiation can cause cells and even genes in the body to mutate in a short period of time.
Then, after death... their bodies gradually returned to the form they had before the mutation during life.
This requires many external force conditions to be met before such a situation is possible.
After investigation and research, the Americans began to conclude that this so-called dark forest was definitely not like this before. There must be a very strong radiation source in it that would cause biological mutations in this area.
, and it can also cause organisms to mutate in a short period of time!
Someone once did research over the dark forest and found that many of the trees here are over a hundred meters tall. There are densely packed strange leaves and vines on them, blocking out the sky and the sun. Looking from above, you can't see anything at all.
To the gap, no wonder, there is no light in the dark forest...
