Mutations Are More Likely to Occur in Repeated DNA Sequences

Multiple Choice

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.
