Bodnar et al (1998)used telomerase to extend the life span of normal human cells.Telomere shortening puts a limit on the number of times a cell can divide.How might adding telomerase affect cellular aging?

Question

Quizplus · Accepted Answer

Adding telomerase would ensure that the ends of the chromosomes (telomeres) are accurately replicated, thus preventing the shortening of telomeres. This, in turn, would extend the life of the cell and delay cellular aging. Therefore, Option B is the correct answer. Option A is incorrect because the addition of telomerase would not necessarily speed up the rate of cell proliferation. Option C is incorrect because telomerase prevents telomere shortening, which actually delays cellular aging. Option D is incorrect because telomerase would have a significant effect on delaying cellular aging.
