Age related decreases in the volume of fat cells in the subcutaneous layer may be caused by telomere shortening, and can lead to more noticeable wrinkles and sagging; Sunlight may contribute to this degradation of the dermis; Sunlight does not appear to shorten telomeres
Telomerase replaces short bits of DNA known as telomeres, which are otherwise shortened when a cell divides via mitosis. In normal circumstances, absent telomerase, if a cell divides recursively, at some point the progeny reach their Hayflick limit, which is believed to be between 50â70 cell divisions.elomerase is a reverse transcriptase enzyme that carries its own RNA molecule (with the pattern of  C C C A A U C C C  in vertebrates), which is used as a template when it elongates telomeres.
