Eukaryotes solve the problem of replicating the ends of their linear chromosomes by:
A) terminal redundancy whereby each end of the chromosome is duplicated allowing recombination.
B) using a protein as a primer.
C) by covalently linking the two strands at each end of the linear chromosome to form a circle.
D) enzyme activity that uses an RNA template and reverse transcription in a series of repeat cycles.
E) all of the above.

Question

Quizplus · Accepted Answer

Eukaryotes use the enzyme telomerase, which carries its own RNA template, to extend the telomeres of chromosomes through a mechanism involving reverse transcription. This process compensates for the shortening of chromosomes that occurs during DNA replication.
