Chapter: 27

After dismissing the unsightly Feng Dongdong , Tian Jingzhi went back to the room and called Zhang Xuanxuan. Zhang Xuanxuan is having dinner with her fiancé Hong Shiguang at the moment. Although Tian Jingzhi knew that their engagement was just a commercial marriage, and they might not necessarily get married and have children, he still couldn't help but wonder: "When will we come out for a meal together, let me meet you, who is called 'the light of the world' 's fiancé."

"He hasn't been feeling well recently. I told him that I will ask him to come and visit the set next time I film."

Tian Jingzhi flicked his hair amorously, "Okay, I will definitely not wash my hair for three days before meeting him, and use my unkempt face to set off your beauty and elegance."

Zhang Xuanxuan sneered, and unceremoniously stabbed a knife in her chest, "I beg you, please dress up carefully. Don't forget that you are just a goddess of housewives, and I am a national goddess who kills all men, women and children. Your pure face is in my heart." It really doesn't have any lethality in front of it."

Tian Jingzhi silently put a big label on Zhang Xuanxuan: Best Lost Friend of the Year Golden Raspberry Award .

If it is said that the most popular teacher in the School of Life Sciences of F University, Ye Chen is definitely the undisputed number one. He has a deceptively good skin, young and knowledgeable. If you haven't seen him in class, then he will definitely be regarded as a noble son who emits hormones anytime and anywhere.

Back then, Tian Jingzhi was deceived by his appearance, thinking that he was pure and reliable, but after dating, he discovered that his appearance was definitely the biggest deception for "human scum".

Of course, Ye Chen's impression of her was also surprisingly consistent.

"The other name of mitochondria is power house, the power plant of the cell." Ye Chen pinched the chalk and wrote the English word for generator on the blackboard, "Every division of mitochondria will cause irreparable damage, resulting in shortening of telomeres. When When the telomere is shortened to a certain extent, the power plant begins to collapse until it completely loses the ability to divide, and the human body has also completed the process from birth to death. As long as the degree of cell division increases to a certain extent, the wound can be healed quickly. However, human cells The number of splits is limited."

Some students in the audience raised their hands.

Ye Chen stopped and looked over with a smile: "What's wrong with this classmate?"

"However, cancer cells can divide indefinitely."

Ye Chen nodded approvingly, "Very good question...the reason why cancer cells can divide and multiply indefinitely is because when they rebel from normal cells to cancer cells, they take away an accomplice called 'telomerase'. Telomerase is in the The use in normal cells is limited, but in cancer cells it can repair telomeres that are shortened during division... One day we can use this telomerase to normal cells and turn normal cells into immortal cells At this time, the problem of human anti-aging will get a qualitative breakthrough. If we can find more perfect repair enzyme than telomerase, it is no joke at all that human beings will not grow old or die.”

After the class ended, the students left one after another. After Ye Chen sorted out the lesson plans, his cell phone rang suddenly, it was from his assistant Lingling.

"Ms. Ye, the PPT of the gene repair plan has been modified according to your request."

"Thank you for your hard work, you have changed so many times."

"Sure, I can just learn more things. But, Mr. Ye, did Professor Li really find a more perfect repair enzyme than telomerase in the hair sample sent more than two months ago? No. Is the sample contaminated?"

"The sample test is the responsibility of the teacher alone. I didn't participate, but there should be nothing wrong." Ye Chen was a little curious, "Why do you doubt it?"

Lingling expressed her guess, "The repair enzyme that is more perfect than telomerase in normal cells is unlikely to be a substance synthesized spontaneously by the human body."

Ye Chen nodded, "You are right, so I suspect that a beneficial gene mutation was triggered in that sample during his lifetime."

Lingling was taken aback, "Before she was alive? The last hair sample was from a dead person?"

Thinking of the lost mummy, Ye Chen smiled wryly. A long time has passed since the car accident, but the investigation of the case has still made no progress. After hanging up the phone, Ye Chen noticed that there was a person sitting in the last row of the classroom, and he waited patiently for him to finish his call. He really said that Cao Cao would be here soon, "When did you come?"

Li Yanzhi thought about it seriously, "When you said that 'as long as the cell division speed increases to a certain level, the wound can heal quickly'."

"What do you think?"

"I only hope that the birth rate and death rate of human beings are within a normal and controllable range, which can maintain the sustainable development of the earth's resources. It is not a malignant expansion of the population with only birth rate and no death rate, just like cancer cells on the earth."
