According to one version of biological clock theories of aging, there is a limit to the number of times each cell can divide before it dies. One limiting mechanism that appears to be involved centers on DNA sequences, called telomeres, which lie at the tips of chromosomes. Research shows that with each cell division, the length of the telomere becomes shorter; after about 60 to 80 cell divisions, there is no longer enough telomere left for cells to reproduce, and they ultimately die.
