633 Start lecture(1/2)
The sudden noise cheered up Yang Xiaotao, and his face regained confidence.
When the applause stopped, the host's voice sounded again.
"Here, I would like to announce a piece of good news. Share this joy with everyone."
The middle-aged man said with a smile on his face, and Yang Xiaotao announced to everyone with a smile on his face but a blank expression, "Comrade Yang Xiaotao, in addition to his achievements in hybrid corn, has also made important breakthroughs in biological genetic research.
.”
"The paper he wrote personally, Gene Mutation, was published in the journal Nature. This is of great significance to our country's biology. His research direction opened a new door for me to develop biology..."
As the host's voice fell, a sound of surprise suddenly sounded in the auditorium.
Everyone has heard of the influence of Nature newspapers on science around the world. Being able to publish a paper on it has no doubt about its authenticity, scientific nature and importance.
Even the experts in the front row were shocked. They had never heard of anyone in China doing it in so many years.
Yang Xiaotao looked normal, but felt nervous inside.
Looking at the expressions of everyone in the audience, they felt a little helpless.
It’s early to become famous, but you also need to have strong skills.
Then he looked at Dean Deng, who was in the middle of the row in front of him. He was very suspicious that he had arranged these remarks.
After the host finished his introduction, warm applause erupted from below again.
It wasn't until the host handed over the microphone and walked off the stage that the applause from below slowly subsided.
Yang Xiaotao took the microphone with helplessness on his face. This was completely inconsistent with the low-key tone he wanted.
Seeing Yang Xiaotao pick up the microphone, the venue was quiet, waiting for Yang Xiaotao to speak.
"Hello everyone, I am Yang Xiaotao!"
Facing hundreds of people in the audience, Yang Xiaotao's voice was trembling when he spoke.
But his mentality soon adjusted. Although these people were much more numerous than the students in Yangjiazhuang, and their age and status were also different, at this moment, standing here, he was the teacher, and those below him were the students.
What's so stressful about teaching students?
Yang Xiaotao breathed a sigh of relief and regained his composure. Everyone's eyes were on him.
Turn around, pick up the chalk and write a few big words on the blackboard.
"The topic I brought today is hybrid corn and genetic mutation!"
After saying that, everyone below has started recording in their notebooks.
Many people showed excitement. They had obviously heard about hybrid corn. Looking at the word "gene" at the back, even a few people in the front row listened intently.
However, Yang Xiaotao was not in a hurry to explain.
"Before the lecture, I need three pairs of men and women who know each other to come forward to help. Is there anyone who can volunteer?"
The scene was silent for a moment, with no response.
Then I saw An Ran holding Yu Hua's hand up.
"Okay, you two!"
The two of them kept looking at Yang Xiaotao, and Yang Xiaotao also paid attention to the two of them and called their names immediately.
Soon, two more pairs of people ran onto the stage.
Faced with this unique method, the people below watched with great interest, and even Dean Deng showed interest.
This way of interaction is more profound than the characters on the blackboard.
"Okay, I guess you two must be from the same place, or are familiar with each other."
Six people nodded.
"Okay, let's get to the point!"
Yang Xiaotao asked a few people to stand aside, and then stood in the center, "Everyone saw it, there are three pairs of people coming up!"
"I gave each pair of them a name. Remember, everyone, from now on, they are not people, but corns!"
Everyone laughed, and the six people on the stage also laughed.
Especially An Ran and the other two, they were able to listen at a close distance and participate in it. If they go back and tell the teacher, they will definitely be praised.
"The code names for you two are long and short, the boy is long and the girl is short!"
"The code names for you two are big and small, the boy is small and the girl is big!"
"You two codenames will not fail, the male will, but the female will not!"
"Do you remember everything?"
The six people nodded in unison.
"Okay, then, let me tell you the rules first."
"Among these six people, when a boy and a girl are together, everyone can only call the boy by his code name. Do you remember that?"
The person below nodded.
"Then, I'll start arranging it!"
Yang Xiaotao began to direct several people to stand together.
"Now, six people stand together, please call me their names."
"Long little down!"
"Very good, everyone responded quickly!"
"Then, the girls come out and everyone calls out their names."
"It's too short to fail!"
"correct!"
"Then, here comes the question. I want to find a long, big, and durable name. How should I combine it?"
"How about we let them do it themselves!"
Soon, the six people stood up where they were.
A man and two women stand together.
"Right!"
Everyone below nodded.
Yang Xiaotao walked up and asked, "Do you know how many possibilities there are to find such a perfect combination?"
"There are many math students here, please give me an accurate answer!"
"Eight kinds!"
Someone shouted, and Yang Xiaotao raised his hand and extended his thumb.
"that's right!"
"I'm just saying that the chance of them getting together is one in eight!"
"Do you think it's easy?" Yang Xiaotao stood aside and said to everyone with a smile, "I think it's easy too, because that's how hybrid corn is produced."
"Thank you guys, please go aside and have a rest."
An Ran followed Yang Xiaotao's hand and immediately walked to the side of the podium and sat down cross-legged, right in front.
Several other people saw it and quickly sat down.
Yang Xiaotao wrote on the blackboard: long stick, big grain, resistant to lodging.
Then write the matching English letters below.
Three minutes later, a complete genetic combination appeared in front of everyone.
"That's the whole story of how hybrid corn came about."
"First, I confirmed the appearance of corn, like long and short."
"Then determine the dominant and recessive genes that control the two phenotypes. Just like when a boy and a girl were together and called the boy code, the boy is dominant and the girl is recessive!"
"The last step is combination. When boys and girls are combined together, they will produce different traits. This combination is genetic recombination."
…
In the next half hour, Yang Xiaotao finished explaining the principles, processes and changes of hybrid corn. The scene was completely silent as everyone digested everything Yang Xiaotao said.
Some people who have studied hybridization know that the seemingly clear and clear flow chart above is actually the result of countless days and nights of hard work.
It is easiest to discover things from one to a hundred, but it is rare to discover things from zero to one.
It's a discovery.
And Yang Xiaotao is the discoverer. He has opened a door and found a way. The rest of the people only need to follow this path and continue to go all the way.
And after that, no matter where it develops, people will remember that the person who opened this door in the first place was named Yang Xiaotao.
To be continued...
