Telomere Shortening Puts a Limit on the Number of Times

Multiple Choice

Telomere shortening puts a limit on the number of times a cell can divide. Research has shown that telomerase can extend the life span of cultured human cells. Which of the following best explains the effect of telomerase on cellular aging?

A) Telomerase will speed up the rate of cell proliferation.
B) Telomerase can eliminate telomere shortening and slows aging.
C) Telomerase shortens telomeres, which delays cellular aging.
D) Telomerase would have no effect on cellular aging.
