103. Telomeres and cloning, answer the cloning issues covered in the previous chapter
Telomeres and Cloning, Answering the Cloning Questions Covered in the Previous Chapter
First, let’s talk about telomeres. That is, humans are composed of countless cells, and the DNA sequence of each cell is fixed from birth.
Telomeres are special structures composed of short multiple repeated non-transcribed sequences of DNA (TTAGGG) and some binding proteins.
Telomeres are located at the ends of chromosomes and generally consist of repeated tandem (TTAGGG) sequences.
Telomere length is considered an indicator of biological aging. Every time a cell undergoes replication, it loses about 50-100 DNA base sequences at the end.
As telomeres become shorter and shorter, cells can no longer divide, triggering aging or death.
Thus, telomere shortening is a well-characterized mechanism of cellular aging, and current evidence suggests that short telomere syndromes contribute to age-related diseases.
However, whether having too long telomeres is advantageous for cells or even individuals is still open to question.
Recent studies have shown that long telomere syndrome, in which telomeres are too long, does not bring longevity to people, but may increase people's risk of cancer.
A simple metaphor: telomeres are cell replication values. This value is related to how many cells you can replicate in your lifetime. When you run out of them, you will die of old age.
The longer the telomeres are, the higher this value will be and the longer you will live. However, because there are many replicating cells, there is a certain risk of cells becoming cancerous every time they are replicated, so longevity may not be guaranteed.
Back to the topic, although human cloning technology is not allowed by law, many biological companies are already doing it secretly.
Otherwise, are so many wealthy people stupid enough to spend so much money investing in biomedicine and genetic technology?
Call me Li Hugua, this old man is so old but he is still alive and causing harm to others, and he still wants to live forever. It is absolutely ridiculous.
Cloning technology is good everywhere, but if the problem of the upper limit of telomere replication and the problem of telomere replication mutation are not solved, it will be impossible for those rich people to live forever.
If you clone yourself using fifty-year-old cells, the telomeres of the clone you are born will start from fifty, which is not easy to use. But if a baby is cloned, the telomeres of the baby clone will be brand new.
So, the world will become more and more magical in the future. Maybe one day, a rich man will go bankrupt in Bengbu, and a bunch of twins and triplets will suddenly appear.
Don't doubt it, he must have secretly cloned it.
This kind of cloning is not only for the future safety of the children, but also for oneself.
The simplest thing is that he has dozens of biological sons of the same blood type, and transfusing the blood of his cloned son or daughter twice a week can keep him young.
Let’s name Li Hugua. I doubt whether he has ever transfused young people’s blood.
Many hormones secreted during human development can also be extracted from clones.
Don't dare to think about it.
Well, brothers, sisters, friends, make more money.
In this day and age, it is too easy to have enough money to live to be a hundred years old.
