46. How does the enzyme telomerase meet the challenge of replicating the ends of linear chromosomes?
(A) It adds numerous GC pairs, which resist hydrolysis and maintain chromosome integrity.
(B) It catalyzes the shortening of telomeres, compensating for the elongation that could occur during replication without telomerase activity.
(C) It adds a single 5' cap structure that resists degradation by nucleases.
(D) It is a reverse transcriptase that carries its own RNA molecule that works as a template to lengthen telomeres.
(E) It causes specific double-strand DNA breaks that result in blunt ends on both strands.
答案：D
