Rebirth of the God-level Xueba

Under the supervision of the staff of the bank and the Construction Bureau, dozens of courtyard houses belonging to Yang Rui were vacated. They were originally used as warehouses, like many courtyard houses of this period.

The difference is that other courtyard houses are mostly stocked with daily necessities, such as firewood, rice, oil, salt, soap, enamel basins, etc., either to prevent price increases, or simply to hoard them.

During this period of time, domestic prices have been soaring at a rate of more than 30% per month. One yuan of soap yesterday became one yuan and three the next day. People have to wonder what happened to their wages.

In contrast, the growth of housing prices is very limited, especially when everyone spends money on daily necessities, and there is even less money to buy real estate.

The only thing that troubled Yang Rui was the relocation of the collections in the courtyard, but it didn't take long.

As the person in charge of the 8811 project, Yang Rui didn't even need to do these things himself, Comrade Geng Xin would be happy to help.

As the safety director of Peking University's ion channel laboratory, Geng Xin's position has also risen with the tide, and he was promoted to the deputy director of safety of the 8811 project in one go-such an important project, the director of such an important project must naturally be held by the head of an important department.

Of course, the most important thing in a research institution is always the laboratory.

and experimental animals...

"The 100th, send them all!" The cadres of China Animal Husbandry put marks on the sheep one by one, and said by the way: "The type of sheep you want is quite strange. You have caught all the domestic varieties. This crossbreed , I don’t know if it tastes good, but there are probably not many good-looking ones.”

The sheep whose symbol was drawn just now looked back at the cadre of Zhongmu, then turned back and walked forward slowly.

Xu Zhengping, who was in charge of receiving, coughed and said, "Eat."

"Eat breeding sheep? You are really going to set a precedent." Even if the cadres of China Animal Husbandry are not working in the front line, they can clearly distinguish the difference between breeding sheep and ordinary sheep.

Xu Zhengping said something wrong for a moment, and his eyes froze.

Geng Xin, who was watching from the side, walked over with a blank expression on his face, and said, "Take out your ID."

"What are you doing?"

"This is mine." Bo Gengxin flashed his red notebook, which immediately made the cadres of China Animal Husbandry flustered.

"I... what do you want my ID for?"

"I now suspect that you are spying on intelligence. Show me your ID." Bo Gengxin's voice was neither loud nor harsh, but the listeners felt guilty.

"No... I just asked a few casually... that..."

"Don't say what you shouldn't say, and don't ask what you shouldn't ask. Before you came, no one taught you? All right, bring your ID and follow me to the office." Bo Gengxin gestured with his eyes, and saw the two A strong man in uniform stood behind the cadre from Zhongmu.

"It's okay, it's okay, just ask questions." Xu Zhengping explained to the onlookers while comforting the cadres who were taken away.

The people who came to deliver the goods were terrified, and after a quick handover, they quickly slipped away.

China Animal Husbandry was originally a state-owned enterprise, and it also had its own security department internally, so it might be subject to some kind of censorship when it goes back.

Xu Zhengping went back to report to Yang Rui, and said, "Should I tell the director, don't make such a fuss..."

"How do you know it's a big deal." Yang Rui curled his lips and said, "We don't understand the matter of security, so we leave it to Geng Xin to do it. People in state-owned enterprises are used to it casually, so it's good to remind them."

"Don't affect others for the rest of their lives." Xu Zhengping personally handed it over, feeling a little sorry.

Yang Rui nodded and said, "You can communicate about this."

As long as it is not included in the file, it will not have much impact, and Geng Xin will be cautious in this regard.

While speaking, Yang Rui also scanned the newly arrived materials.

Cloning is an expensive activity. Around 2000, the cost of cloning mammals with off-the-shelf equipment and instruments was also around one million, depending on the difficulty of different animals.

However, the cost in the late 1980s and the cost in 2000 are two completely different concepts.

Semi-commercial off-the-shelf instruments and equipment and the development of new equipment are two concepts.

It's like ordinary people going to the hospital to take an MRI film, and the price ranges from hundreds to thousands of yuan. However, how much does it cost to develop a set of MRI equipment?

There is no need for development, just buying an MRI equipment can cause headaches for ordinary hospitals.

To be the first, the cost is naturally the first.

It took a lot of time and energy just to collect all kinds of sheep.

Historically, the cloned sheep made by the British were made of two Finnish Dorsetham sheep and a Scottish black-faced sheep. On the one hand, the characteristics of the black-faced sheep are more obvious. There is no black face in the eyes, and I know whether it is successful or not.

On the other hand, the Roslin Institute is originally located in Scotland, and has a series of corresponding research on Scottish black-faced sheep, which can reduce some steps and count some steps.

When it came to Yang Rui, it would be foolish for the laboratory to adopt Scottish black-faced sheep again. Although it can also reduce the corresponding cost if it is completely imitated, it is too troublesome to explain.

In fact, shortly after Dolly was born, the Northwest Agriculture and Forestry University in China cloned goats, using their own breed of dairy goats, Xinongsha Neng dairy goats.

However, although goats and sheep are both sheep, the cloning of goats is more complicated. Without the background of cloning sheep, the difficulty factor increases instead.

Yang Rui would rather choose a suitable one among the many domestic sheep breeds.

In this regard, there is really no experience to follow.

Even in the 21st century, cloning remains an expensive research project. For the first somatic cell cloned animal, it is cost-effective to spend hundreds of millions of dollars, but for the second or third, it is not worth spending so much.

Therefore, after somatic cell cloning, the quasi-repetitive experiments that we do are all kinds of different animals. Clone monkeys, cloned cows, cloned cats and dogs, etc. have appeared one after another, but no one will try to clone a second breed of sheep, or a third breed of cow.

Therefore, it is also difficult for Yang Rui to find the second article, which is not a sheep clone article using Scottish blackface sheep.

In this way, there are still some difficulties that need to be overcome.

Don't look at the simple steps, that is, just plug the somatic cells into the recipient cells, but the actual implementation is far from that simple. The most typical one is dog cloning.

People all over the world know that dog cloning is of great commercial value. Whether it is an owner who never forgets his dog or a lover who needs some rare breeds, it represents a steady stream of gold dollars.

Then, since the cloned sheep Dolly was born in 1996, dog cloning was not realized until 2005, and it took almost the same time as Dolly.

Could it be that scientists all over the world are brain hypoxic and stupid?

Of course not, the main difficulty of dog cloning lies in the difficulty of enucleating the eggs of dogs, and the very complicated physiological characteristics of reproduction, which are difficult to be manipulated by others.

The selection that Yang Rui needs to do must also avoid these minefields.

If he chooses wrongly, his advantage may become a disadvantage.

The researchers in the ion channel laboratory and genetic engineering laboratory were not as nervous as Yang Rui. After he announced the project content, all that was left for everyone was excitement.

clone!

For biologists, it is already an academic masterpiece.
