The cellular clock theory proposes that cells have a limited number of divisions before they stop dividing, and this limit is linked to the shortening of telomeres, the protective ends of chromosomes. As cells divide, their telomeres become shorter until they become critically short and the cell can no longer divide, leading to cell death and tissue aging. Therefore, telomeres become the major means of aging cells in the cellular clock theory.
