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

A) It adds a single 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

The correct answer is C) It catalyzes the lengthening of telomeres, compensating for the shortening that could occur during replication without telomerase activity.

Explanation:

While replicating, the ends of the chromosomes always lose a part of the ends, therefore, the telomerase catalyzes this growing process, somehow compensating the information that will be lost.
