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. How might adding telomerase affect cellular ageing?

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