Chapter 219 (2/2)
”What a pity! It's so green without any precaution! ”
”When you are trying to snap with your wife, you will come up with a picture of someone who looks the same as your wife lying under someone else...”
”The way of city people is deep. I want to go back to the countryside!”
”The world is really going to be ruined!”
”The state should promulgate relevant laws as soon as possible!”

The disturbance of the outside world did not affect Zhang Wei. He lived a quite regular life as before. He studied regeneration ability in the company during the day and went to the astronaut training base of the company at night for training. Of course, occasionally I will have time to spend time with Ren Huaiyu.
During this period, Zhang Wei not only studied Jiangshan's genes, but also studied salamander, zebrafish and multi fin fish, three kinds of creatures with regeneration ability.
After research and analysis, Zhang Wei found the same gene feature related to limb regeneration in these three different creatures. However, the limb types of these creatures are different, which shows that nature has written a gene 'manual' for controlling limb regeneration. All kinds of animals are generally applicable, including humans.
Next, Zhang Wei analyzed the germ cells of the three animals separately. Bud base is the key first step in the process of rebirth. Zhang Wei found that the bud base in all three organisms contains a group of the same genes, which are controlled by a group of gene regulators called microRNA.
Micro RNA is a short gene sequence, which is responsible for regulating gene expression. Zhang Wei has identified ten kinds of micro RNA molecules, which play a role in the limb regeneration of newt, zebrafish and multipiper fish. In the process of limb regeneration, five kinds of microRNAs are active, while the other five are closed.
Later, Zhang Wei studied Jiang Shan's blood and found four kinds of special RNA fragments. According to his prediction, if these genes are activated, human beings may have the ability of limb regeneration.

Time is in a hurry. Unconsciously, another week has passed.
16 January.
In the scientific research building.
Zhang Wei looked at a tube of green liquid in front of him, his eyes full of expectation. (to be continued. )
