When Zhou Wen rushed to the testing center, he happened to meet Wu Yan when he passed by the administrative building, and there was a boy holding flowers next to him.

The boy looks a little milky, wears a brand-name dress, and has a shiny stud earring on his left ear.

Seeing Zhou Wen, Wu Yan said hello, "You just came back?"

Zhou Wen: "Uh...... Well. ”

"Let's go together, I just have something to tell you. Saying that, Wu Yan walked towards him.

The boy followed and handed over the flowers in his hand, "Yanyan, don't do this, give me another chance, I promise ......"

Wu Yan stopped, looked at the boy and said seriously: "Your promise is like a fart, do you think I will still believe it?"

"Yeonyan ......"

"Get out. ”

After speaking, Wu Yan walked up to Zhou Wen and said, "Let's go." ”

Zhou Wen and Wu Yan walked side by side towards the testing building, and glanced at the man with studs, and the other party saw Wu Yan leave without looking back, stood there and hesitated for a while, and finally turned around and walked towards the parking lot of the inpatient department.

"My ex-boyfriend. ”

"Hmm!"

"Scumbag. ”

"Oh~"

He ...... Forget it, let's not talk about it. ”

"An elder told me today that it doesn't matter what you have experienced, what is important is what experiences and lessons you have learned from these experiences?"

"Hmm!" Wu Yan nodded and said, "Just now there was a meeting in the hospital and said that at the end of the month, there will be an exchange and study meeting in hospitals in the province, and our testing system will also send people to participate." ”

Zhou Wen said strangely: "What are you telling me? This kind of paid opportunity to eat, drink and have fun is not our turn. ”

Wu Yan said: "Then you are wrong, this time it is not just about eating, drinking and having fun, but also about moving seriously, when the time comes, the representatives of various hospital departments will come to the stage to show their business capabilities, and they don't dare to go if they want to go without two brushes." ”

Zhou Wen smiled: "That's okay, our testing center is like a cloud, so it won't be our turn to play a little shrimp." ”

"That's going to have to be compared. This time, you can't just go with old qualifications, but also have a good level of business. ”

"What do you mean, you want me to participate?"

"What do you say?" Wu Yan smiled, "DNA extraction is 1 hour and 17 minutes, I dare not say that it is the fastest in the province, among all the experimenters in our hospital, you are definitely in the top three, as for whether you can rank first, you will only know after the comparison."

In addition, I heard Bian Wenhao and Su Qi say that your level of PCR is higher than theirs. ”

Zhou Wen waved his hand, "No, no, no, what is my level......

Before Zhou Wen finished speaking, there was a prompt sound in his ears.

Wu Yan invites you to participate in the provincial exchange and study, please ask if you accept ......]

Hearing the prompt in his ear, Zhou Wen's tongue turned, "Okay...... Since you think so highly of me, senior sister, then I'll give it a try, when?"

Wu Yan glanced at him, and always felt that he had promised too much...... Blunt.

Obviously he was so resolute just now, why did his words change in a blink of an eye?

There is a stream of starvation and not eating the food that comes from it, and then it is really fragrant.

The two of them chatted and went back to the lab.

On the way, he glanced at the mission requirements.

[Task: Communicate and learn

Requirements: On behalf of the PCR group, participate in the provincial exchange and study meeting.

Rewards: 300 subject experience, 300 points, 1 chance to unpack (wood)]

Although it is a wooden box, no matter how small the mosquito legs are, they are still meat.

Zhou Wen didn't take the task immediately, he wanted to do a few more sets of genetic improvement experiments before going to exchange and study.

Back in the third-floor lab, he continued to observe the genetic characteristics of aphids.

Cage No. 1.

Cage No. 2.

Cage No. 3.

Cage No. 4.

No. 5 cage ......

1、2、3、4、5、6…… 178，179。

"Huh, no?" When Zhou Wen observed the No. 7 cage, he found that the number of aphids inside was obviously wrong.

According to these experiments, aphids can reproduce about 250~350 aphid offspring in one generation under the optimal temperature and humidity, and this number is significantly less.

He entered the data into the computer.

Then the characteristics of the aphids in cage 7 were observed.

He found that the number of aphid deformities in this area was obviously more than the previous cages, either with crooked noses and squinted eyes, or missing arms and legs, and even some of them even had genetic mutations.

Zhou Wen was very excited, he felt that there was going to be a major breakthrough this time.

He immediately inquired about the biochemical agents used in cage No. 7 and the proportions.

"Mercury sulfide, methylhalomycin, quinenone......"

After finding it, he didn't look at the remaining 40 or so cages, because it was no longer necessary.

Now that we have found a formula for modifying genes, we will continue to deepen our research on this formula.

He started to re-medicate, and the dosage was added strictly as required.

This is no joke, one microliter more and one microliter less can be the opposite.

He made 50 copies at once, and it took less than twenty minutes.

Then start spraying the rice leaves.

After the rice leaves were sprayed, the cages containing the aphids were cleaned up, leaving only one cage and the aphids that were thriving inside.

He then packs the rice leaves into clean cages and carefully loads the aphids into the cages with small tweezers.

After everything was done, Zhou Wen looked at the time, it was already five o'clock.

He stood up and rubbed his hands together and prayed, "You're God's favorite cub, rush, Pikachu!"

【Experimental Acceleration】

A mysterious force shrouded the cage in the laboratory, and in the next second, the aphids in the box completed the reproduction of a generation.

Zhou Wen immediately went to see the cage.

The first box, 1, 2, 3, 4, 5, 6...... 190。

"it-" When he finished counting, Zhou Wen was so excited that he almost didn't jump up, he was really the chosen son.

This amount, compared with the previous 20 experiments, is 25%~30% less on average.

Second cage, 185.

The third cage, 164.

Fourth cage, 171.

……

Zhou Wen counted ten boxes in a row, and none of the boxes contained more than 200 rice aphids.

And not surprisingly, the rice aphids in each box have a large number of deformities.

This proves that the heavy metal chemical drugs he prepared have indeed worked on genetic inheritance.

However, it is still too early to rejoice, and it is necessary to continue to observe the reproduction of the next generation of rice aphids.

Because the first generation of aphid deformities caused by drugs does not mean that the next generation will also be deformed.

As long as there is an aphid gene in it that is not attacked by heavy metal pesticides, it can reproduce healthy offspring aphids that will continue to damage crops.

Then genetic improvement is considered a failure.

So the next step is to take out the aphids that are not affected in the box and continue the second generation experiment......

At half past five, Sun Jing came over and called Zhou Wen to go to dinner, and when she saw that the computer in the laboratory was still looking at it, she asked, "Is it going to be all night at night?"

Zhou Wen: "Hmm!"

"Even though you're young, you still have to pay attention to your body. ”

"I know ......"

After eating, Zhou Wen started the second-generation experiment non-stop.

This time is different from before, there is no need to spray rice leaves with chemicals.

Because the "mothers" of these aphids have ingested drugs and have been genetically modified, genetic inheritance determines that even if they eat pollution-free and pollution-free rice leaves, the offspring they produce still have a high mortality rate, and they lack arms and legs.

And that's what genetic modification is for!

Because the step of configuring the spraying drug was omitted, a lot of time was saved, and only an hour and a half later, the second generation of results came out, and the aphid's genes were really changed.

The number of aphids that have bred in the second generation is still much smaller, and many of them are deformed.

"Hahaha......"

Zhou Wen was excited and excited, and continued the experiment of the third generation.

The result is still the same.

Then came the fourth generation, the fifth generation......

I did it for 5 generations without any accidents.

The die is cast!

……

……

A week later, on Friday night, May 11, Wang Huiyao was having dinner when the phone rang.

When I picked it up, it was an unfamiliar number.

"I'm Wang Huiyao, who are you?"

"Hello Professor Wang, I'm Zhou Wen. ”

"What's the matter with you? ”

"That's the professor, I've been working on the genetic ...... of improved rice aphids all this time."

"Ahem, cough, ahem......" Wang Huiyao was choked by Zhou Wen's words, "What, what? You are studying the genetic improvement of rice aphids?"

After finishing speaking, Wang Huiyao had a feeling of ridicule.

Doesn't this Zhou Wen speak through the brain?

Does he know what genetic modification is?

This is a huge systematic project, which requires countless manpower, material resources, financial resources and time to have a slight probability of success.

With him as an undergraduate, what can he do to improve?

It's ridiculous!

"Yes, Professor Wang, after my research during this time, I have found some ......"

Wang Huiyao didn't wait for him to finish before interrupting: "Okay, if you don't have anything to do, I'll hang up first." ”

As he spoke, Wang Huiyao was about to hang up the phone.

Zhou Wen hurriedly shouted: "Wait a minute, Professor Wang, I really have made a major discovery, after my genetic modification technology, the reproduction rate of rice aphids has decreased by an average of 30%. I've already sent the paper to your mailbox, if you don't believe it, just take a look at it. ”

30% is already Zhou Wen's very modest words, in fact, counting those deformed aphids, the reproduction rate has been reduced by at least more than 40%.

"I see~"

After speaking, Wang Huiyao hung up the phone very impatiently......
