"Telomere" is a DNA repeat sequence at the end of eukaryotic chromosomes, which functions to maintain the integrity of chromosomes and control the cycle of cell division. Simply put, genes that control lifespan.189Please respect copyright.ＰＥＮＡＮＡCtXASWaW4A
After Dolly was born, it was found that the biggest difference between it and ordinary sheep was that it aged quickly. At age 6, she developed arthritis that usually develops in old age. She was later pronounced dead from pneumonia. However, Dolly the sheep, who can live to be 6 years old, also gave the researchers a boost.189Please respect copyright.ＰＥＮＡＮＡsIoHGoTRkf
Even though... there are many voices against copying animals in the world, these voices all believe that this move will "reduce biodiversity because the copied animals are all derived from the same parent organism", "destroy the natural food chain", "the cost of copying animals" Expensive can't reduce famine at all", "the original animal's right to live is violated", "duplicating animals has security risks" and so on...189Please respect copyright.ＰＥＮＡＮＡRtBBLhx07D
And later, there was a breakthrough in the cloning of cattle! The study found that the cows were actually younger than their actual age. The reason is that their telomeres are not only back to the length they were born with, they are also longer than they would normally be at birth. This means that they can live longer than the average cow, but extremes also seem to be the law, with overgrowth of telomeres leading to premature death.189Please respect copyright.ＰＥＮＡＮＡgMeaaB01E1
Nonetheless, researchers are very confident that related research can eventually be used to change human lifespan!
Change life? Is it used to change whose life? Will it be for you, for the general public like me?
