Question

what best describes the potential role of telomeres in the aging process? select one a. they are the packets of fuel that feed each cell. b. they are \glue\ that binds together the base pairs of dna molecules. c. they are a portion of a chromosome that gets shorter until dna replication is no longer possible. d. they are the scrubber cells that clear all debris from our arteries.

Explanation:

Telomeres are repetitive sequences at the ends of chromosomes. With each cell - division, telomeres get shorter. Eventually, when they become too short, DNA replication can no longer occur properly, which is associated with the aging process.

Answer:

C. They are a portion of a chromosome that gets shorter until DNA replication is no longer possible.
