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

The difference is that most of the other courtyards are stocked with daily necessities, such as firewood, rice, oil, salt, soap, enamel pots and the like, either to prevent price increases, or simply to hoard.

During this time, domestic prices are soaring at a rate of more than 30% per month, and the soap that was a dollar yesterday has become three yuan the next day, which has to make people wonder what happened to their wages.

In contrast, the growth of house prices is limited, especially when everyone spends money on daily necessities and even less money to buy property.

The only thing that made Yang Rui a little troublesome was that the collection in the courtyard had to be relocated, but it wouldn't take long.

As the person in charge of the 8811 project, Yang Rui didn't even need to do these things in person, and Comrade Geng Xin was happy to serve.

As the safety director of the Ion Channel Laboratory of Peking University, Gengxin's position is also rising, and he was promoted to the deputy director of safety of the 8811 project in one breath - such an important project, the director is naturally the leader of the important department.

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

and experimental animals......

"The 100th, all delivered!" The cadres of the middle herd, one by one, drew a charge on the sheep, and said casually: "The sheep species you want are quite strange, and the domestic breeds let you catch them all, this hybrid is out, I don't know if it's delicious, and there are probably not a few good-looking ones." ”

The sheep that had just been drawn with a symbol looked back at the cadre who was pasting in the eye, then turned back and walked forward slowly.

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

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

Xu Zhengping said the wrong thing for a while, and his eyes froze.

Geng Xin, who was watching from the side, walked over expressionlessly and said, "Take out your documents." ”

"What for?"

"This is mine. Booklet Gengxin lit up his big red notebook, which immediately made the cadres of Zhongmu panic.

"I ...... What do you want my documents for?"

"I suspect you're spying on intelligence right now. Get your documents out. Geng Xin's voice was neither loud nor small, nor harsh, but the listeners felt very weak.

"It's not...... I just asked casually...... That ......"

"Don't say what you shouldn't say, don't ask what you shouldn't ask, no one taught you before you came? Okay, come with me to the office with your documents. Book Gengxin gestured with his eyes, and saw two strong men in uniform, standing behind the cadres from Zhongmulai.

"It's okay, it's okay, it's just asking. Xu Zhengping comforted the cadres who were taken away, and explained to the onlookers.

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

China Animal Husbandry was originally a central enterprise, and it also has its own security department, so it may be subject to some scrutiny when it goes back.

Xu Zhengping went back to report to Yang Rui and said, "Do you want to tell the director of the book, don't make too much of a fuss......

"How do you know it's a big deal. Yang Rui pursed his lips and said, "We don't understand the things we defend, so we'll leave it to Gengxin to do." People in state-owned enterprises are used to it, so it's good to remind them. ”

"Don't affect people for the rest of your life. Xu Zhengping handed it over in person, and he was a little reluctant to go.

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

As long as you don't enter the file, it won't have much impact, and Gengxin will be cautious in this regard.

While speaking, Yang Rui also swept through the newly arrived materials.

Cloning is a costly activity, and around the year 2000, the cost of cloning mammals with ready-made equipment and instruments was also in the millions, depending on the difficulty of different animals.

But the cost of the late 80s, and the cost of the 2000s, are two very different concepts.

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

It's like an ordinary person going to the hospital to take an MRI film, and the price ranges from a few hundred yuan to a thousand yuan. But how much does it cost to develop a set of NMR equipment?

You don't need to develop it, even if you buy an MRI device, it can give ordinary hospitals a headache.

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

It takes a lot of time and effort just to collect all kinds of sheep.

Historically, the cloned sheep made by the British were made of two Finnish Dosetsem sheep and a Scottish black-faced sheep, on the one hand, the characteristics of the black-faced sheep are more obvious, and the lambs born by the ewes have no black face with their eyes, and they know that the success has not succeeded.

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

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

In fact, not long after Dolly was born, Northwest A&F University in China made a clone of goats, using their own dairy goat breed, Xinong Shaneng dairy goats.

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

Yang Ruining can choose the suitable one among the many sheep breeds in China.

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

Even in the 21st century, cloning is still a costly research project. It costs hundreds of millions of dollars to clone an animal in the first somatic cell, but it's not worth spending so much for the second or third.

Therefore, after the somatic cell cloning, the repeat experiments that we do are all different animals. Cloning monkeys, cloning cows, cloning cats and dogs, and so on, but no one is trying to clone a second breed of sheep, or a third breed of cattle.

Therefore, it is also difficult for Yang Rui to find a second article, which is not a cloned article of sheep with Scottish black-faced sheep.

As a result, there are still some difficulties that need to be overcome.

Don't look at the steps, that is, just stuff the somatic cells into the recipient cells, but it is far from being so simple. The most typical is cloning dogs.

People all over the world know that cloning dogs is very commercially valuable, whether it is an owner who is obsessed with a dog, or a lover who has a demand for certain scarce breeds, it represents a steady stream of gold dollars.

Then, since the birth of Dolly the sheep in '96, the dog cloning was not realized until 2005, which took about the same amount of time as Dolly.

Could it be that scientists all over the world are stupid because of the lack of oxygen in their brains?

Of course not, the main difficulty of cloning a dog is that the egg-enucleation of the dog is difficult, and there are very complex reproductive physiology that are difficult to manipulate.

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

If he chooses the wrong one, his advantage may become a disadvantage.

The researchers in the ion channel laboratory and the genetic engineering laboratory were not as nervous as Yang Rui, and after he announced the content of the project, everyone was left with excitement.

Clone!

For biologists, it's already an academic climax.
