WebApr 13, 2024 · Thus, the telomeres are like a biological clock, counting down the total number of times that a cell can divide. This limit to cell division is known as the Hayflick limit (after Leonard Hayflick who discovered it in the 19603). The Hayflick limit is different for each species. The Hayflick limit has been found to correlate with the length of the telomeric region at the end of chromosomes. During the process of DNA replication of a chromosome, small segments of DNA within each telomere are unable to be copied and are lost.
