Chapter 1716 Perfect Gene Extraction Skills

But what's more funny is that Li Tian dances pretty well, and he looks good.

Such an alternative square dance naturally attracted a lot of onlookers, and quickly became the leader of the entire square dance.

Many middle-aged and elderly women looked at Li Tian with admiration, and after Li Tian finished a dance, they also asked Li Tian if he was married. He was a high-ranking woman there, and wanted to introduce his unmarried daughter to him. Li Tian, ​​so as to make a good thing.

However, Li Tian did not refuse.

When he came back, he even said to Zhou Ruihan, "Look, am I good?"

Zhou Ruihan was quite speechless about this, and rolled her eyes and said, "You can do it, you are amazing, your harem will soon be too small to live in a community."

Li Tian laughed, then said to Zhou Ruihan, "Let's go, let's go eat something delicious."

…

Li Tian was so happy, of course, because a voice appeared in his mind. [Congratulations on completing the task, reward 200,000 yuan in cash red envelopes, 2,000 lottery points, and 2,000 system experience points. 】

After completing the task, Li Tian was of course happier, and then he went home with Zhou Ruihan.

Of course, after getting in the car, Li Tian immediately took off all the glowing light sticks on his body.

Seeing this scene, Zhou Ruihan couldn't help laughing: "Why don't you keep it?"

Li Tian smiled and said, "Do you like it? If you like it, then I will keep it."

"..."

Zhou Ruihan didn't know what to say to such a shameless man.

…

But this time the two went straight home, and Li Tian personally made a large table of delicious food for Zhou Ruihan, but Zhou Ruihan was moved.

Li Tian's cooking skills are of course not to be said, Zhou Ruihan eats deliciously.

In the evening, grown men and women have a romantic evening.

…

After Zhou Ruihan fell asleep, Li Tian turned on his system.

[Current system level is 50, total experience value: 178651]

After using the good luck card, just click to confirm the draw.

[Congratulations for winning a 10,000 yuan cash red envelope. 】

[Congratulations for winning a 10,000 yuan cash red envelope. 】

[Congratulations for getting 2 [Good Luck Cards] in the lottery. 】

[Congratulations for winning 2 [Danger Prediction Capsules] in the lottery. 】

[Congratulations for winning 4 [5 times a day card] in the lottery. 】

[Congratulations for winning 2 [Random Special Mission Cards] by lottery. 】

[Congratulations for winning 2 large bottles of [Evolutionary Fast Forward Potion] by lottery. 】

[Congratulations for getting 2 level 50 special props [Golden Skill Card Fragments] by lottery. 】

【…】

What makes Li Tian happy is not only the time doubling card, but also successfully allowing Li Tian to continuously gain the ability to multiply time.

At the same time, what made Li Tian the happiest was the golden skill card. Because of this, Li Tian successfully obtained 11 shards.

He didn't hesitate, and immediately clicked to combine.

Then Li Tian really got a new special ability.

[Congratulations on obtaining the perfect gene extraction skill. 】

Seeing this new skill, Li Tian's joy is indescribable. Sure enough, what he needs, as long as he works hard, the system will give it.

In the newly built biological laboratory, Li Tian searched for medicinal materials all over the world in order to treat Zhao Wan'er's disease. Among them, the DNA of the three most important medicinal materials is difficult to be extracted by current medicine.

But with this new skill, Li Tian obviously has a new approach.

A gene (genetic element) is the entire sequence of nucleotides required to produce a polypeptide chain or functional RNA.

Genes support the basic structure and performance of life. It stores all the information about the race, blood type, gestation, growth, apoptosis and other processes of life.

The interdependence of environment and genetics deduces important physiological processes such as reproduction of life, cell division and protein synthesis. All life phenomena such as the growth, growth, decline, disease, aging, and death of an organism are related to genes. It is also an internal factor that determines the health of life.

…

DNA segments with genetic information are called genes, and other DNA sequences, some directly function in their own structure, and some are involved in regulating the expression of genetic information.

A simple life requires at least 265 to 350 genes.

Li Tian has studied and researched these important information.

Genetic DNA, not only living things, but also plants.

plant genes

By artificial methods, exogenous gene fragments and vector DNA are extracted from different organisms, and after in vitro cutting, splicing and recombination, a certain method is used to introduce the recombined vector DNA with exogenous genes into plant cells, and make It replicates and expresses in plant cells to achieve the desired purpose of changing the genetic characteristics of the recipient plant cells. This process is called plant genetic engineering.

The above are conventional methods. If Li Tian wants to extract DNA from fossils, it is not so easy.

…

Li Tian rested with Zhou Ruihan here.

On the other side of him, 24 hours later, people have come to the medical laboratory.

Top medical experts are recruited here.

The most common method for DNA extraction from fossils is silica extraction, which is based on the adsorption of DNA molecules on silica. By taking a small amount of bone meal from the fossil, dissolving it in a specific solvent containing silica and centrifuging, the DNA in the bone meal is adsorbed on the silica.

In addition, polymerase chain reaction (PCR) is also a commonly used method in ancient human DNA extraction, which uses DNA polymerase in cells to extract DNA fragments.

However, neither of these two methods can perfectly successfully resurrect the medicinal material fossils.

Li Tian put on a special sterile suit.

Fossils of medicinal materials from 10,000 years ago are extremely precious, and even the entire earth is the only one. If Li Tian fails, it will undoubtedly be difficult to rely on the records in the "Shen Nong Medical Book" to successfully treat Zhao Wan'er.

…

When Li Tian was working, other experts could temporarily leave work early.

Because Li Tian will use the perfect gene extraction skill next, he is the first time to use this special high-tech skill.

I saw that after he used it, golden rays of light appeared on his body, and then these rays of light were attached to his fingers, and then under a series of incredible operations, the fossil medicinal materials that had been stored for thousands of years were cut open like this.

Immediately afterward, a medicinal aura that was difficult to see with the naked eye was wrapped in golden light, successfully fused with the ancient DNA, and finally refined.

Li Tian carefully placed it in the culture tank, and then poured in a little fast-forward potion with even trembling fingers.

Then, a miraculous scene appeared.

That one, the magical medicinal herb that existed in ancient times, was miraculously resurrected like this.

Li Tian was not stingy, he was very excited.

Not only was Zhao Wan'er's illness saved, but also the sense of accomplishment of reviving the medicinal materials from ten thousand years ago is simply indescribable.

…

Then poured the fast-forward potion, and the medicinal materials grew miraculously. Li Tian used his crossbreeding skills to successfully cultivate more than a dozen trees, and poured the fast-forward potion again.

call--

Li Tian finally breathed a sigh of relief, because at this moment he finally succeeded in resurrecting a medicinal material ten thousand years ago perfectly, and also cultivated more than a dozen trees at once. In the future, these dozen trees will develop hundreds of thousands, millions of trees .
