How Does the Enzyme Telomerase Meet the Challenge of Replicating

question 47

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 catalyses 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.
