The enzyme telomerase solves the problem of replication at the ends of linear chromosomes by which method?
A)adding a single 5' cap structure that resists degradation by nucleases
B)causing specific double-strand DNA breaks that result in blunt ends on both strands
C)causing linear ends of the newly replicated DNA to circularize
D)adding numerous short DNA sequences such as TTAGGG
E)adding numerous GC pairs that resist hydrolysis and maintain chromosome integrity

Question

Quizplus · Accepted Answer

Telomerase adds numerous short DNA sequences, specifically TTAGGG, to the ends of chromosomes. This helps prevent the loss of genetic information caused by the natural termination problem of DNA replication.
