The genetically programmed time limit for cell replication to which each species is theoretically bound is called
A)life expectancy.
B)maximum reproductive capacity.
C)the Hayflick limit.
D)the telomere.

Question

Quizplus · Accepted Answer

The genetically programmed time limit for cell replication is known as the Hayflick limit, named after scientist Leonard Hayflick who discovered it. It is the number of times a cell can divide before it undergoes cell death or becomes senescent. This limit is based on the length of telomeres, which are protective caps on the ends of chromosomes that shorten with each cell division. Once the telomeres become too short, the cell can no longer divide, leading to aging and cell death. Therefore, D (the telomere) is also partially correct but not the best choice, as the telomere is a structure rather than a time limit.
