[10] [11] Examining telomeres is one of the most important fields of research related to aging. It is also very important to investigate the mechanisms of maintaining telomerase, cell cleansing ( old cells that accumulate in tissues and sometimes cause cancer and inflammation) and the production of new cells in long-lived organisms.
