However, the cellular proteins that make this possible replication, can not physically copy the last few bases of DNA at the ends of chromosomes, for each copy it shortens telomeres. If the telomeres do not act as a buffer, in the process of copying a chromosome could be losing a functional gene. This natural "life expectancy" of cells was first identified in the 60's of last century as the "Hayflick limit" and is named after its discoverer Leonard Hayflick (Leonard Hayflick), while the employee Wistar Institute.
