Because not everything can pass through these channels, only the correct substance is recognized by the protein tentacles and is allowed to pass through.

However, the virus is like a cunning fox, the best at deception.

A fake pass is hidden on the shell of the virus, but the virus is too large to pass through these passages.

At this time, the powerful and brainless motor protein, once again played its role as a pig teammate, in the tearing with the protein tentacles, the virus was torn apart, the DNA smoothly entered the nucleus (some viruses are DNA, some are RNA), there are 23,000 genes in animal cells, and the virus has only 40, but only these 40 genes sometimes make the cell burned, and even change the fate of the animal.

The virus involuntarily shows Feifei its deception again and again, it understands the cells of animals and is good at exploiting their weaknesses.

At this moment, a trick of the virus, a bigger scam, and the final life-and-death contest are coming......

The cell's DNA-making machines have no way of telling the cell which is the virus and which is its own genes, and they blindly copy the death code from the virus, and these instructions are executed in the nucleus.

And at this time, it can be said that the happiest moment for the virus, they seem to be singing loudly:

In the nucleus is the garden, the flowers in the garden are so bright, the DNA replicates us, and every virus is smiling.

Wahaha, Wahaha, every virus is smiling.

Come quickly with the new virus, don't avoid the old virus, hold hands and sing that song, how happy our lives are.

Wahaha, Wahaha, how happy our life is.

……

The virus began to command the cells, frantically creating the virus, and Feifei was about to turn defeat into victory and achieve the final victory.

Unexpectedly, at this time, the cell finally realized the invasion of the virus, and the pig-like teammate, the motor protein, began the last rescue, and it used its last strength to transmit a distress message containing a virus fragment to the outside of the cell membrane, sending the last distress signal to the outside world.

If the white blood cells on patrol happen to recognize the distress signal, the white blood cells will destroy the infected cell, along with the virus inside.

However, if the white blood cells do not detect a distress signal, the cells become infected one after another.

At this time, some motor proteins sent out distress signals before dying, but many more motor proteins did not have time to send the last distress message to the cells until they died.

Only a few white blood cells patrolling outside the cell received a distress signal and launched a rescue operation, killing the infected cells along with the virus inside.

However, 24 hours after being infected by the virus, the virus almost completely took control of the cells.

As normal feeding stops, cells begin to decay, but the virus army continues to replicate itself and is ready to go......

At first, maybe it's just a sneeze, a cough, a call from a fox.

Forty-eight hours after being invaded by the virus, the body still has no obvious symptoms, and we usually refer to this period as the "incubation period".

However, before the virus can begin its journey, there are two problems to overcome, the virus army is trapped in the strong nuclear membrane and cell membrane inside the cell, and the ribosomes outside the nucleus begin to make destructive proteins under the instructions of the virus to attack the cell membrane and cytoskeleton, and the cell begins to disintegrate.

At this time, the virus begins to attack the nuclear membrane again, and a substance called the pneumonia virus death protein begins to weaken the nuclear membrane, and the nucleus is finally broken by the surging virus.

In just forty-eight hours, the cells were already powerless.

The virus floods to other tissues in the surrounding area until it spreads throughout the body. For the cell, the war is over.

However, for the animal body, the war has only just begun, and while the virus is busy invading the cells, the fox's body synthesizes a large number of modified antibodies and returns to the battlefield.

Despite the large number of antibodies, they still cannot stop all viruses.

However, they also have reinforcements - white blood cells.

At the end of its life, the motor cell finally made a name for itself, sending the most important alarm signal to the white blood cells.

A large number of white blood cells are accumulating towards the invaded cells and engulfing the virus.

These patrolling white blood cells, very responsible, are desperately searching for viruses everywhere, as if they are still humming while searching:

Look for it, look for it, find a small virus, and eliminate you, you're welcome, I think you're still poisonous.

Look for the virus, find a small virus, kill you, disinfect, I call the virus to all the defeat.

However, in order to be sure, the white blood cells will indiscriminately attack all the cells that may be infected, and this overreaction can cause great and even fatal problems for the fox's body.

A large amount of tissue fluid, which transports white blood cells to the lungs, quickly blocks the lungs, causing the fox to be unable to breathe until it dies.

This time, after a thrilling life-and-death battle, Feifei's virus army turned defeat into victory, won the final victory, and also took the lives of his subordinates (Hongxia'er).

Due to hunger and cold, coupled with extreme depression, the fox's immune system simply did not function as well as it should.

However, under normal circumstances, the war between the virus and the cell mostly ends in the defeat of the virus.

Between cells and viruses, just to survive, there is no right or wrong, what is wrong is the "retrograde angels", it is they who break the natural laws in nature.

This time, it was just because of the special situation that Feifei's "virus cloud" won by luck.

After the victory, Feifei's mood can be described as "mixed tastes", but since then, he has a new understanding of the virus.

After appreciating the power of the virus, he couldn't help but sigh for the virus in his heart:

I'm a little virus, and although I'm as fat as a pig, I'm not confused at all.

My life is the hardest, and there are many disasters and hardships that cannot be counted, and only parasitism can be comfortable.

My enemy is a cell, and there is a trick to defeat the enemy, and I am so coquettish to get through the tricks.

As long as I enter the nucleus, my trick is the most lacking, copying the virus is like being a thief.

Who said that the virus is meaningless, you have no temper when you are sick, even if you have a good body, you will fall to the ground if you are not careful.

When the cell saw that I was not convinced, I gave the cell a plan, as long as the cell didn't pay attention, it would burp later.

Next, how does Feifei plan to survive? At this time, Feifei's mood was very complicated.

Unexpectedly, after the "virus cloud", he had to fight to the death with his subordinates and comrades-in-arms in his previous life, and it was still in the microcosm.

This really made Feifei feel extremely melancholy and depressed.
