How Does the Enzyme Telomerase Meet the Challenge of Replicating

Multiple Choice

How does the enzyme telomerase meet the challenge of replicating the ends of linear chromosomes?

A) It adds a single 5' cap structure that resists degradation by nucleases.
B) It causes specific double-strand DNA breaks that result in blunt ends on both strands.
C) It catalyzes the lengthening of telomeres, compensating for the shortening that could occur during replication without telomerase activity.
D) It adds numerous GC pairs, which resist hydrolysis and maintain chromosome integrity.
