Telomeres are structures that limit the maximum number of times cells can divide.

Question

Quizplus · Accepted Answer

Telomeres are indeed structures that limit the maximum number of times cells can divide. As cells divide, their telomeres shorten, until they reach a critical length that triggers cell death or senescence. This is known as the Hayflick limit. However, certain cells (such as stem cells) are able to maintain their telomere length and continue dividing indefinitely.
