What are telomeres?
#Question id: 3776
#Section 3: Genetics, Cellular and Molecular Biology
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 aging?
