科学家通过对400多人的血液样本进行化验后发现,决定人们寿命的因素取决于端粒(在染色体端位上的着丝点)的长度。从胚胎阶段开始,人体内端粒的长度就在不断缩减。端粒是医药领域中的一个时髦术语,它可以保护人体的脱氧核糖核酸免受损耗。它的长度越长,人的寿命也就越长。脱氧核糖核酸位于人体内每个细胞的中部,
Scientists tested blood samples from more than 400 people and found that the factors that determine the lifespan of people depend on the length of the telomere (centromere at the end of the chromosome). From the embryonic stage, the length of human telomeres is constantly shrinking. Telomere is a fashionable term in the medical field that protects human DNA against depletion. The longer it is, the longer it will live. DNA in the body of each cell in the middle,
