Twenty minutes.

The doppelganger is a robot, and he doesn't know how to be tired or hungry at all.

But Ye Fan still listened to it, if he really said it, it is estimated that it will be able to finish it in a day and a night, right?

Don't say whether the doppelganger is tired or not, he himself is tired.

"Is that enough?"

"How many?"

Ye Fan squinted his eyes slightly and said with a smile.

"Eight hundred and seven... Seventy-six! A math professor looked up and said in a trembling voice.

Rumble!

As soon as these words came out, the scene exploded.

It was extremely quiet just now, but now it is extremely lively.

The two differences are very unique,

Eight hundred and seventy?

Fog grass, these are all things they haven't seen before.

Those candidates were also stunned, and they looked at Ye Fan with wide eyes one by one.

These formulas are all correct.

Because if you calculate according to the formula, the results are the same, they are all mathematical geniuses, although they can't understand the principles of these formulas, but they can still understand the basics, this formula is not wrong, and the answer is not wrong, that is, Ye Fan is not nonsense.

All correct!

Everyone exploded in an instant.

Cracked.

How?

The professor who asked the question just now was really shocked at this moment, and when Ye Fan said countless formulas, Dean Adams, who was in a wheelchair, was also stunned just now, and looked at Ye Fan with a shocked and slightly squinted expression, his expression was very interesting.

"Whether the formula is correct or not, you should know it in your own mind, is there any problem?" Ye Fan looked at the professor and asked.

The mathematics professor was shocked to the point that his scalp was numb at the moment, and when he heard Ye Fan's words, where did he have the courage to continue to ask questions?

The biggest problem in his heart was the problem just now, which had been overcome by Ye Fan.

He didn't have a problem to come up with.

He could only shake his head and say, "Mr. Ye, no, if you have a chance, you must ask Mr. Ye!" ”

"I'd love to know how these formulas work!"

That mathematics professor is very humble, academically unbounded, and the one who is better than you is the teacher.

It's the rule in their industry.

No matter age.

The reporters are shooting frantically, this is the best reversal of the year.

The professor who asked the question instead became the one who wanted to know.

"If you're gone, you'll be next!" Ye Fan said loudly.

Next?

The mist grass on everyone's face.

Isn't this a test for Ye Fan, how did he become some...

"Hello Mr. Ye, I am a biologist Green, my topic is about biology, and it is also the biggest problem in my heart, if Mr. Ye doesn't answer correctly, it doesn't matter..."

If Ye Fan is really a demon and a genius.

So why not say the hardest?

Let Ye Fan answer?

Can you also solve the problems in your mind?

But with so much media here, he is a little ashamed, this is deliberately embarrassing people.

It feels a little shameless.

The reporters were muttering.

But the words have already been said, so it can't be taken back, and the biologist Greene suddenly said with a straight face: "My question involves a wide range of topics such as biotechnology, bioengineering, synthetic biology, and systems biology. ”

"The internal environment of cell growth is dynamically changing, which makes it difficult to achieve stable output of the elements introduced in the cell machine when constructing gene lines or networks.

This topic came out.

There was another uproar at the scene.

Synthetic biology represents semi-biological machinery, has technology begun to develop in this direction?

Many reporters are at a loss, they don't understand.

"Synthetic biology? Hey, that's too hard, isn't it? ”

"How, you know? Let's talk about it! ”

For example, it is often difficult for engineered gene circuits or regulatory networks to achieve stable expression or output in cellular machines, because changes in growth conditions, different growth periods, differences in gene expression, metabolic burden or environmental stress can affect the expression level of the target gene. Gene expression levels are also affected by copy number. ”

"Different replication origins have their own special self-replication initiation mechanisms, which means that different plasmid copy numbers will differ. So is it possible to solve this problem by integrating the gene to be expressed into the genome? The answer is no, because the proximity to the origin of replication of the genome also affects the expression level of the gene. Rapidly dividing bacteria will replicate multiple copies of the genome at the same time, which will cause multiple copies of parts of the genome to exist in the same cell, so related genes close to the origin of genome replication may be destroyed, which is the biggest problem! ”

"Isn't this just throwing a bomb at Ye Fan, who can solve the puzzle?"

"Yes, if you solve the puzzle, wouldn't there be a huge breakthrough in the cyborg of companion organisms? There are many levels that can be used, how can Ye Fan understand it? ”

The candidates for field biology began to discuss with each other, and the reporters listened to it.

Got it.

Anyway, it's another problem of the century.

If it is solved, it will have a huge breakthrough in this technology.

"Did Mr. Ye understand? If I don't understand, I can be in..."Then biology Green is the same as the previous professor, for fear that Ye Fan will not understand, after all, if you say it directly, even if it is other questions, you need to listen more, right?"

And as always.

He hasn't finished speaking, when the scene is restless!

Ye Fan spoke.

"I can submit two answers to this question, and there are two ways to achieve molecular stability in cells! The first is to modify the replication origin of the plasmid so that the copy number of the plasmid itself remains stable; The second protocol is to tune the regulatory modules of gene expression, including the intensity of the promoter, the strength of the ribosomal binding site, and the degradation rate of RNA and protein. ”

Ye Fan's voice fell.

The biological Green's eyes lit up suddenly, and there was still a commotion around him.

Then Green was in a hurry.

Hurriedly yelled: "It's all quiet! ”

As soon as the roar came out, everyone fell silent.

But they all had bewildered expressions on their faces.

What's the situation?

Ye Fan answered?

We didn't hear that.

What are you talking about?

When the biology candidates heard Ye Fan's answer, their eyes lit up slightly, just two sentences broke the problem of stability, if they could be used, wouldn't they have obtained the technology of synthetic biology?

Will there be a breakthrough in synthetic biology?

"Mr. Ye, please tell me how to use these two techniques, can Mr. Ye answer!" That Green's whole person was about to explode, he didn't expect that Ye Fan would be able to answer, as always, in less than a few seconds, he could get the answer, he was about to explode.

I desperately want to know the answer!

....
