Chapter 26 Iconic Flag

In the blink of an eye, more than a month passed quietly.

After more than a month of intense experiments and screening, the research team finally selected two recombinant samples with great potential from a large number of sample libraries.

These two sets of recombinant samples were named Purification No. 1 and No. 2 respectively.

After more than a month of experience in the project, Chen Wenli's work style has become more capable. At this time, she is giving a brief work report to Cheng Xiang, "The two groups of recombinant samples selected have similar abilities and efficiencies in purifying indoor pollution. The most important thing is It’s the living environment that makes the difference.”

"Sample No. 1 is suitable for growing in the gaps between decoration and building materials. According to our tests, No. 1 can survive in the internal environment of decoration and building materials for a long time. Conservative calculation can reach a five-year survival period. The reconstituted sample is composed of formaldehyde, TVOC and benzene. It is a carbon source and a nutrient source to maintain its own metabolism. Therefore, it can be provided directly to building materials manufacturers, and it can be mixed into No. 1 when producing building materials. No. 1 can continuously absorb pollutants released by building materials. "

"Sample No. 2 is suitable for spraying. Once sprayed, it can remain suspended in the air for three to five days, and can survive on the surface of building materials for about a month. It is suitable for home use. One spray can effectively keep the indoor air clean for a month."

"Whether it is No. 1 or No. 2, it can reduce indoor pollution to one order of magnitude below the current indoor air environment standards."

Chen Wenli finished her report quickly, and Cheng Xiang smiled and nodded.

"very good."

"Calculating the time, it has only taken us three months so far." Cheng Xiang said with a smile.

"That's right, three months, it was unimaginable before." Chen Wenli nodded in response.

"The main part of the project has been completed. It's time to start the finishing work. Let's go, I will take you to see my results for more than a month." Cheng Xiang stood up and walked towards the laboratory with Chen Wenli.

"Cleaning up? Are you talking about genetic solidification and sterilization?" Chen Wenli asked.

"That's right, it's the genetic solidification and sterilization technology. It's been done." Cheng Xiang said as he walked.

"You are really fast."

"Haha, that's natural."

Although Chen Wenli has become accustomed to Cheng Xiang's efficiency, even if the man in front of her says that he can build a spaceship tomorrow, she will no longer have the slightest doubt. However, is it really okay for you to talk about two breakthrough technologies in such a nonchalant manner?

Soon, the two rushed to the laboratory, Cheng Xiang's workshop.

"look……"

Cheng Xiang explained while letting Chen Wenli observe.

In the field of view of the electron microscope, Chen Wenli clearly saw the sample yeast with added gene curing technology. She was familiar with the original sample, which was the commonly used one. The density of yeast cells in the sample was good, and there were yeast cells in all stages. Observation It's very convenient to get up.

Soon, Chen Wenli discovered an astonishing scene. When splitting DNA in a considerable number of samples, some yeast cells lost their activity, as if the program had been suspended. The yeast cells that lost activity would gradually be decomposed. Those that divide normally will continue to grow.

Chen Wenli raised her head and looked at Cheng Xiang in disbelief, "Is this gene solidification technology and sterilization?"

Cheng Xiang nodded, "Yes, it is gene curing and sterilization. Biological products without gene curing are life. With the addition of gene curing and locking, biological genes will stay at the current stage from now on. The occurrence of any genetic mutation will lead to Cell genes collapse. Only such biological products are safe enough and are commercial products. There is no need to worry about these biological products suddenly mutating and causing unpredictable harm."

"Genetic sterilization is also based on solidification technology. Every time the maternal gene divides, the marker gene will be recorded. When the number of divisions reaches the preset target value, the marker gene will mutate. The gene mutation activates the collapse chain of gene solidification. .This is sterilization at the genetic level."

"This technology is really scary." Chen Wenli sighed. Unknowingly, they had touched and penetrated into the restricted area of ​​life.

Cheng Xiang shook his head and said with a smile, "Is the mass-energy equation scary? Not scary. Is the atomic bomb scary? It's scary."

"Technology itself is just exploring the nature of the world. The scary thing is always people, not technology."

"Moreover, this kind of technology is not something that just anyone can master."

When Chen Wenli heard what Cheng Xiang said, she immediately calmed down. When she looked at Cheng Xiang again, she couldn't help but smile, "I've been overthinking it. After being with you for so long, I almost thought that everyone in the world was as smart as you. "

Cheng Xiang couldn't help but smile after hearing this.

Buzz!

Buzz!

The phone in his trouser pocket was vibrating crazily. Because he only came to check it temporarily, Cheng Xiang did not put the phone in a special safe. When I took it out, I saw that it was Tang Zhengming who was calling.

"The professor called."

"At this point in time, their verification experiment is probably completed." Chen Wenli guessed.

"Calculating the time, it's almost time." Cheng Xiang nodded in agreement and answered the phone. Before he could speak, he heard the urging voice on the other end of the phone, "Hurry up and come to the dean's office."

"Hurry up!"

"By the way, call Chen Wenli too."

Toot toot!

After hanging up the phone, Cheng Xiang could feel the urgency on the other side.

Chen Wenli couldn't help but laugh out loud, "This is the first time I've seen Professor Tang be so anxious. The professor has always looked serious and unsmiling."

"Perhaps, if we are more serious, the teaching effect will be better?" Cheng Xiang said with a smile.

"maybe."

The two couldn't help but smile at each other.

"Go to the dean's office quickly, don't keep the professor waiting."

Ten minutes later.

Cheng Xiang knocked on the door and pushed it open. The dean's office was already filled with a circle of people. Cheng Xiang took a quick look, and his heart suddenly shuddered. The professors in front of him all had deep-set eye circles, messy hair, and bloodshot eyes. However, each and every one of them had deep-set eyes. The spirits were high, and everyone was staring at Cheng Xiang.

"Come here quickly." Tang Zhengming was no exception. He still had the calmness and calmness of the past. He took two hurried steps and pulled Cheng Xiang to the middle of the office.

"This is my student, Cheng Xiang. He is also the creator of this precise gene cutting theory."

Bang bang bang, thunderous applause.

"Let me tell you, initially, I was planning to take Cheng Xiang together to develop targeted drugs."

"Fortunately, Cheng Xiang is more assertive. After a trip to the Municipal Cancer Hospital, he made a special trip to inspect the children's leukemia department. He realized the pain caused by decoration pollution to children and families, and decided to devote himself to the topic of indoor pollution control."

"It is for this reason that the theory of precise gene cutting was born."

"Cheng Xiang, am I right?" Tang Zhengming was very excited. Cheng Xiang felt that he could just be a quiet tool and nodded in agreement.

The professors applauded again.

Words such as young and promising, young talent and so on kept getting into Cheng Xiang's ears.

The professors were so enthusiastic that Cheng Xiang could only smile and return the favor one by one.

Tang Zhengming was pleased and patted Cheng Xiang on the shoulder, "Cheng Xiang, the verification experiment plan has been fully implemented. Your theory is completely correct."

"The paper you prepared, as well as the part of the experimental data that we can disclose, have been submitted to Tianwen, China's most outstanding scientific journal, as soon as possible."

"It won't be long before there will be an earthquake in the field of genetic engineering because of your theory."

"And you will also become an iconic flag of our School of Biology, Xiangnan University!" Tang Zhengming proudly announced.

"I will continue to work hard." Cheng Xiang replied firmly.

The professors applauded warmly.
