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.

Question

Quizplus · Accepted Answer

Telomerase catalyzes the lengthening of telomeres, which are specialized structures at the ends of linear chromosomes, compensating for the shortening that could occur during replication without telomerase activity. This allows for the complete replication of the chromosome without losing important genetic information at the end of the chromosome.
