Which statement describes the function of telomeres?
A) Telomeres are DNA segments that encode cell cycle checkpoint proteins.
B) Telomeres are where DNA polymerase binds to initiate DNA replication.
C) Telomeres serve as attachment points where microtubules bind to separate chromosomes during anaphase.
D) Telomeres are added to chromosomes with each round of replication to increase DNA stability.
E) Telomeres protect the coding regions of chromosomes because chromosomes are shortened with each round of replication.

Quizplus · Accepted Answer

Telomeres are repetitive nucleotide sequences at the ends of chromosomes that protect the coding regions of DNA from being eroded during the replication process. Since DNA polymerase cannot replicate the very end of a chromosome, telomeres prevent the loss of important genetic information by being shortened instead of the coding regions.
