Mutations are more likely to occur in repeated DNA sequences because
A)these bases are unstable.
B)bases in the strand can form base pairs,generating loops that interfere with replication and repair enzymes.
C)the repeats hold onto the replication enzymes,causing base mismatches.
D)the repeats attract and bind to mutagens,increasing the mutation rate.

Question

Quizplus · Accepted Answer

Repeated DNA sequences can form loops during replication and repair, which can interfere with the enzymes responsible for those processes. This increases the likelihood of base mismatches and mutations. Additionally, repeated sequences can be more prone to slippage during replication, further promoting mutation.
