Which of the following best characterizes the cellular clock theory of aging?

Question

Quizplus · Accepted Answer

The cellular clock theory of aging suggests that cells can divide only a certain number of times, and once that limit is reached, the cells become senescent (unable to divide further) and eventually die, contributing to the aging process. This is due to the shortening of telomeres with each cell division, which eventually leads to DNA damage and cellular dysfunction. Therefore, telomeres do not contradict this theory but rather provide a mechanism for how cellular aging can occur. The theory also does not suggest that everyone has the exact same rate of aging or that cells from longer-lived species divide fewer times than cells from shorter-lived species.
