DNA-containing telomeres, at the ends of chromosomes, become so short that the cells die. Telomerase plays a surprisingly important role in cancer and aging. In a cancer cell telomerase is highly active and adds telomere DNA, preventing telomere shortening and extending the life of the cell. Telomerase is an enzyme that maintains the DNA at the ends of our chromosomes.
I think its good to know that they know what makes the cells age faster. wiyh this information i think that scientists can use this information and somehow prevent the aging of cells and extending the life of cells.
