The sudden sound made Yang Xiaotao cheer up and regain confidence on his face.

Until the applause stopped, the host's voice sounded again.

"Here, I would like to announce one more piece of good news. Share this joy with everyone. ”

The middle-aged man said with a smile on his face, and announced to everyone in Yang Xiaotao's smiling but dazed expression, "Comrade Yang Xiaotao, in addition to his achievements in hybrid corn, he has also made important breakthroughs in biological gene research. ”

"The paper he personally presided over and wrote, the gene mutation, was published in the journal "Nature", which is of great significance in my country's biology, and his research direction has opened a new door for my biological development......"

As the host's voice fell, a sound of surprise suddenly rang out in the auditorium.

Everyone has heard of the influence of the natural press on science all over the world, and there is no doubt about the authenticity, scientificity, and importance of being able to publish papers on it.

Even the experts in the front row were shocked, they had never heard of anyone in the country for so many years.

Yang Xiaotao's face was normal, but he was nervous in his heart.

looked at the expressions of everyone in the audience, a little helpless.

It's too early to become famous, but you also have to have excellent skills.

looked at Dean Deng in the middle of the row in front of him, he was very suspicious, and he arranged these words.

After the host finished the introduction, there was warm applause below.

It wasn't until the host handed over the microphone and walked off the stage that the applause below slowly subsided.

Yang Xiaotao took the microphone with a helpless expression on his face, which was completely inconsistent with the low-key he thought.

Watching Yang Xiaotao pick up the microphone, there was silence in the venue, waiting for Yang Xiaotao to speak.

"Hello everyone, I'm Yang Xiaotao!"

Facing hundreds of people in the audience, Yang Xiaotao's voice trembled a little when he said it.

But soon the mentality was adjusted, although there were many more people than the students in Yangjiazhuang, and their ages and identities were also different, but at this time, standing here, he was the teacher, and the students below.

What is there to be nervous about teaching students?

Yang Xiaotao breathed a sigh of relief and found his state, and everyone's eyes were on him.

Turn around, pick up the chalk and brush on the blackboard and write a few large characters.

"The topic I'm bringing today is hybrid corn and genetic mutations!"

After saying that, the people below have already begun to record in the book.

Many people showed excited expressions, obviously having heard of hybrid corn, looking at the two words gene in the back, even a few people in the front row also listened attentively.

However, Yang Xiaotao did not rush to explain.

"Before the lecture, I need three pairs of men and women who know each other to come up and help, do you volunteer?"

There was silence for a moment, and there was no reaction.

Then I saw An Ran pulling Yu Hua and raising his hand.

"Okay, you two!"

The two kept looking at Yang Xiaotao, and Yang Xiaotao also paid attention to the two of them, and immediately called names.

Soon, two more pairs ran onto the stage.

In the face of this unique way, the people below looked at it for a long time, and even Dean Deng showed interest.

This way of interaction is more profound than the characters on the blackboard.

"Okay, I guess your pair must be from the same place, or familiar with each other."

The six nodded.

"Alright, let's get down to business!"

Yang Xiaotao asked a few people to stand aside, and then stood in the center, "Everyone saw it, there were three pairs of people who came up!" ”

"I give each of them a name. Remember, from now on, they're not people, but, corn! ”

Everyone laughed, and so did the six people on stage.

Especially An Ran, the two of them were able to listen to it up close, and they also participated in it, and they would definitely be praised when they went back to tell the teacher.

"The code name of the two of you is long, the male is long, and the female is short!"

"The code names of the two of you are big and small, the male is small, and the female is big!"

"The code names of the two of you don't fall, the men don't fall, the women don't fall!"

"Do you remember them all?"

The six nodded in unison.

"Okay, then, I'll tell you the rules first."

"Among the six people, when the boy and the girl are together, everyone can only call the boy's code name. Remember that? ”

The person below nodded.

"So, I'm starting to line up!"

Yang Xiaotao began to command several people to stand together.

"Now, the six of you are standing together, please call me their names."

"Grow and pour!"

"Very good, everyone responded quickly!"

"Then, the girls are out of the queue, and everyone shouts their names."

"It's too short!"

"That's right!"

"So, here's the problem. I'm trying to find long, big, and non-falling names, how do I put them together? ”

"Shall we let them do it themselves?"

Soon, the six of them were standing in place.

A man and two women stand together.

"Right!"

The crowd below nodded.

Yang Xiaotao walked up, "Then do you know, how many possibilities are there to find such a perfect combination?" ”

"There are a lot of math students here, give me an accurate answer!"

"Eight!"

Someone shouted out, and Yang Xiaotao raised his hand and stretched out his thumb.

"That's right!"

"I'm just saying that the odds of them coming together like this are one in eight!"

"Do you think it's easy?" Yang Xiaotao stood aside and said to everyone with a smile, "I also think it's simple, because that's how hybrid corn comes out." ”

"Thank you, please come and rest."

An Ran followed Yang Xiaotao's hand and immediately walked to the side of the podium, sat down cross-legged, just in front.

Several other people saw it and quickly sat down.

Yang Xiaotao wrote on the blackboard long sticks, large grains, anti-lodging.

Then write the matching letters below.

Three minutes later, a complete genetic combination appeared in front of everyone.

"That's how hybrid corn came about."

"First of all, I confirmed that the corn behaves like long and short."

"Then determine the dominant and recessive genes that control the two phenotypes, just like the boy and girl were together just now, called the boy code, the boy is dominant, and the girl is recessive!"

"Finally, there is the combination, the combination of boys and girls will produce different traits, and this combination is genetic recombination."

……

In the next half an hour, Yang Xiaotao finished talking about the principle process of hybrid corn and the changes in existence, and the scene was silent, and everyone was digesting everything Yang Xiaotao said.

Some people who have studied hybridization know that the flowchart that seems clear and unambiguous above is actually the result of countless days and nights of hard work.

The discovery of things from one to one hundred is the simplest, and it is rare to be from zero to one.

It's discovery.

And Yang Xiaotao is this discoverer, he has opened a door and found the way, and the rest of the people only need to expand according to this road, and they can go all the way.

And after that, no matter where it develops, people will remember that the person who pushed open this door at the beginning was called Yang Xiaotao.

As for the others, it is only through the explanation to remember what is called hybrid corn and how to get hybrid corn.

After Yang Xiaotao finished talking about hybrid corn, let everyone digest it for a while, and then changed the topic to talk about genetic mutations.

"After listening to it for so long, have you noticed that there is a term that appears often?"

Yang Xiaotao said, and then redrew the two words gene on the blackboard.

"So, can anyone explain what genes are, or what do you think genes are?"

The voice fell, and the audience was silent, and no one answered.

Some, cold field.

This scene caught Yang Xiaotao off guard, it stands to reason that this thing should not be like this, it should be unheard of.

Just as Yang Xiaotao was about to open his mouth to explain, an old man in the front row raised his hand.

"Hello, Mr. Yang!"

"I'm a biology teacher at the Academy of Agricultural Sciences, and my surname is Zhou!"

The old man's title made Yang Xiaotao stunned, but he quickly reacted.

"Hello, Mr. Zhou."

Yang Xiaotao hurriedly responded.

Someone immediately whispered in the venue, although Yang Xiaotao didn't know this person, but judging from everyone's reactions, this person was, an expert.

"Mr. Yang, I have read your paper on hybrid corn and your paper on gene mutations, and I have written it very deeply."

"Thank you for the compliment."

Zhou Lao waved his hand, "Don't be modest, we are here, and the master is the teacher." Don't look at me as older, but I've eaten a few more years of salt and read a few more books than you. ”

"To be able to hear knowledge here, to hear the truth, to die at night."

Teacher Zhou smiled and said to a few people around him, and several people laughed together.

Subsequently, Mr. Zhou began to talk about his own opinions.

"In my opinion, genes are the genetic code, the code that can pass on certain characteristics from one parent to the next generation."

"This kind of password, in the reorganization of the two sides, forms a new individual."

"Just like our ancestors said, dragons give birth to dragons, phoenixes give birth to phoenixes, and rats are born to make holes."

After Teacher Zhou finished speaking, Yang Xiaotao nodded.

"Thank you Mr. Zhou for your explanation, it is very incisive."

"Just like Mr. Zhou said, each race has special genes and has a unique way of inheritance......

Yang Xiaotao pointed to the English letters on the blackboard, "Just like these letters, each of them represents the genetic code, expressed in their own way..."

"The insulin we talked about is actually protein."

"The amino acids that make up proteins are arranged and combined in a specific way, and why they are arranged in this combination, or the template that manipulates the arrangement of these amino acids, I think is the gene."

Yang Xiaotao said his thoughts, which included some understanding of later generations, as well as his own views on the times.

It's not that I don't know the process of gene replication, transcription, and translation, but now I say it, without a factual basis as a basis, and there are not enough hard conditions.

However, Yang Xiaotao was not too conservative, and after thinking for a moment, he still picked up chalk and drew a chain on the blackboard.

"It was Mr. Wang's lesson yesterday that inspired me, and I have a conjecture here."

"If insulin is a product of some kind of genetic control, can we work backwards and reverse the genes through the amino acids that make up proteins?"

"I have deduced it in private, but it is immature, where is it for everyone's reference."

At this point, several people in the front row could no longer sit still, and some experts with reading glasses took out handkerchiefs and began to wipe the spectacle lenses, trying to take a closer look.

In particular, Wang Guangmei, who gave a lecture yesterday, stood up and walked to the front of the first row to sit down, looking at the blackboard carefully.

They really didn't think about it.

Because insulin hasn't worked yet!

"That's what I thought last night."

Yang Xiaotao looked at the two lines on the blackboard, and shamelessly pressed the discoveries of the future generations on himself.

However, having said that, it is not certain whether there are those people in this world or not, and we can't wait for those who may not exist to advance science.

If you have to do it, make an insurance.

Yes, this is Yang Xiaotao's self-comfort, which works very well.
