The cellular clock theory sees aging as a process whereby cells are assumed to have a limitation on the number of times they can replicate. This is due to the shortening of telomeres, which are sequences of DNA on the ends of chromosomes that protect them from damage. As cells divide, telomeres become shorter until eventually, the cell can no longer divide, resulting in aging.
