Supreme Pharmacist System Chapter 41: Successful genetic modification
When Zhou Wen rushed to the testing center, he happened to bump into Wu Yan as he passed the administrative building, next to a boy holding flowers.
The boy looks a little milky, dressed in designer clothes, and has a shiny ear stud on his left ear.
Seeing Zhou Wen, Wu Yan greeted, "You just came back?"
Zhou Wen: "Uh... um."
"Let's go together, I just have something to tell you." 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 and looked at the boy seriously and said, "Your promise is like a fart, do you think I will still believe it?"
"Yanyan..."
"Roll."
After finishing speaking, Wu Yan walked to Zhou Wen and said, "Let's go."
Zhou Wen and Wu Yan walked side by side toward the testing building. Out of the corner of the eye, he glanced at the man with ear studs. Seeing that Wu Yan left without turning his head, he stood there for a while, and finally turned around and parked in the inpatient department. Field gone.
"My ex-boyfriend."
"Yeah!"
"Scumbag."
"Oh~"
"He... Forget it, let's not talk about it."
"An elder told me today that what you have experienced is not important, but what experiences and lessons have you learned from these experiences?"
"Yeah!" Wu Yan nodded and said, "The meeting in the hospital just now said that there will be a provincial hospital exchange and study meeting at the end of the month, and our testing system will also send people to participate."
Zhou Wen said strangely: "What are you telling me? This kind of opportunity to eat, drink and play with pay is not our turn."
Wu Yan said: "Then you're wrong, this time it's not just about eating, drinking, and having fun, but also for real. When the time comes, the representatives of each hospital department will be on stage to demonstrate their business capabilities. If you don't have two brushes, you won't dare to go. ."
Zhou Wen said with a smile: "That's fine. Our testing center has experts like clouds, so it's not our turn to play."
"Then you have to compare it before you know it. This time, you can go there not just on the basis of qualifications, but also with excellent business skills."
"What do you mean, you want me to participate?"
"What do you think?" Wu Yan smiled, "DNA extraction takes 1 hour and 17 minutes, I can't say that it is the fastest in the province. Among all the laboratory staff in our hospital, you are definitely in the top three. You can't rank first, you'll know after you compare.
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, what's my level..."
Before Zhou Wen finished speaking, a prompt sounded from his ear.
[Ding! Wu Yan invites you to participate in the exchange and study in the province, may I ask if you accept...]
Hearing the prompt in his ear, Zhou Wen turned his tongue, "Okay... Since you look down on me so much, senior, let me try it, when?"
Wu Yan glanced at him, always feeling that his promise was too... blunt.
He was so determined just now, why did his words change in a blink of an eye?
There is such a thing as to starve to death and not eat the food that came, and then it is really fragrant.
The two chatted and returned to the laboratory.
On the way, he glanced at the mission requirements.
[Mission: Communication and Learning
Requirements: On behalf of the PCR group, participate in the provincial exchange and study meeting.
Reward: 300 subject experience points, 300 points, one chance to open the box (wood)]
Although it's a wooden box, no matter how small the mosquito's legs are, it's still meat.
Zhou Wen didn't take the task immediately. He wanted to do a few more sets of genetic improvement experiments before he went to exchange and study.
Back in the laboratory on the third floor, he continued to observe the genetic characteristics of aphids.
Cage No. 1.
Cage No. 2.
Cage No. 3.
Cage No. 4.
Cage No. 5...
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 in it was obviously wrong.
According to the experiments of these days, under the optimal temperature and humidity, aphids can normally reproduce about 250~350 aphid offspring in one generation, and this number is obviously much less.
He entered the data into the computer.
Then began to observe the characteristics of the aphids in cage No. 7.
He found that the number of malformed aphids in this place is obviously more than the previous few cages. Either the nose is crooked, the eyes are slanted, the arms and legs are missing, and some even have genetic mutations.
Zhou Wen was very excited. He felt that there would be a major breakthrough this time.
He immediately inquired about the biochemical agents used in the No. 7 cage, as well as the proportions.
"Mercury sulfide, methyl salinomycin, quinocetone..."
After finding it, he didn't go to observe the remaining more than 40 cages, because it was no longer necessary.
Now that the formula for genetic modification has been found, then it is enough to focus on this formula and continue to deepen the research.
He began to re-medicate, and the doses were added exactly as required.
This is no joke, one microliter more and one less microliter can be the opposite.
He made 50 all at once, and it took less than twenty minutes.
Then start spraying rice leaves.
After the rice leaves were sprayed, the cages containing the aphids were cleaned up, leaving only one cage and the thriving aphids inside.
He then put the rice leaves into those clean cages, and then carefully loaded the aphids into the cages with small tweezers.
After everything was done, Zhou Wen looked at the time, it was five o'clock.
He stood up and rubbed his hands, praying, "You are God's favorite cub, go ahead, Pikachu!"
【Experiment Acceleration】
A mysterious force enveloped the cage in the laboratory, and the next second, the aphids in the box completed a generation of reproduction.
Zhou Wen immediately went to see the cage.
The first box, 1, 2, 3, 4, 5, 6... 190.
"Fuck—" After counting, Zhou Wen was so excited that he almost didn't jump up, he was indeed the son of heaven.
This number is 25%~30% lower on average than the previous 20 experiments.
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 unsurprisingly, the rice aphids in each box have a large number of deformities.
This proves that the heavy metal chemical drugs he prepared have indeed had an effect on genetic inheritance.
However, it is still too early to be happy, and it is necessary to continue to observe the next generation of rice aphids.
The deformity of the first generation of aphids caused by the drug does not mean that the next generation will be deformed.
As long as there is an aphid gene in it that is immune to heavy metal pesticides, it can produce healthy offspring aphids that continue to harm crops.
Then genetic improvement is a failure.
So the next step is to take out the unaffected aphids from the box and continue with the second generation of experiments...
At half past five, Sun Jing came over and called Zhou Wen to have dinner. Seeing that the computer in the laboratory was still watching, she asked, "Are you going to stay all night again?"
Zhou Wen: "Yeah!"
"Although you are young, you still need to pay attention to your body."
"I know..."
After eating, Zhou Wen started the second-generation experiment without stopping.
This time is different from before, there is no need to spray chemicals on rice leaves.
Because the "mothers" of these aphids have already ingested drugs, their genes have been modified, and genetics have determined that even if they eat pollution-free and pollution-free rice leaves, the offspring they produce will still have a high mortality rate, and Missing arms and legs.
And that's what genetic modification is for!
Because the steps of configuring spraying drugs are omitted, it saves a lot of time. After only an hour and a half, the results of the second generation came out, and the genes of the aphids were really changed.
The number of aphids produced by the second generation is still much smaller, and many of them are deformed.
"Hahaha..."
Zhou Wen is excited and excited to continue the experiment of the third generation.
The result is still the same.
And then the fourth generation, the fifth generation...
I did it for 5 generations without any surprises.
The big picture is set!
…
…
A week later, on Friday night, May 11, ~IndoMTL.com~ Wang Huiyao was having dinner when the phone rang.
When I picked it up, it was an unfamiliar number.
"I am Wang Huiyao, who are you?"
"Hello, Professor Wang, I'm Zhou Wen."
"What's the matter with you?"
"It's such a professor. During this time, I have been studying the genes for improving rice aphids..."
"Cough cough..." Wang Huiyao was choked by Zhou Wen's words, "What, what? Are you researching the genetic improvement of rice aphids?"
After speaking, Wang Huiyao had a feeling of irony and laughter.
Does this Zhou Wen speak without going through his brain?
Does he know what genetic modification is?
This is a huge systematic project that requires countless human, material and financial resources and time to have a slight chance of success.
As an undergraduate, what can he do to improve? mouth?
That's ridiculous!
"Yes, Professor Wang, after my research for a while, I found some..."
Wang Huiyao interrupted before he finished speaking: "Okay, if you have nothing to do, I will hang up first."
After speaking, Wang Huiyao planned to hang up the phone.
Zhou Wen hurriedly shouted: "Wait, Professor Wang, I really have made a major discovery. After my genetic modification technology, the reproduction rate of rice aphids has dropped by an average of 30%. I have sent the paper to your mailbox. If you don't believe me, you can see it by looking at it."
30% is already a very modest word from Zhou Wen. In fact, including those deformed aphids, the reproduction rate has been reduced by at least 40%.
"I know~"
After speaking, Wang Huiyao hung up the phone impatiently...
