Multiple Choice
An alternative repair system by error-prone translesion DNA synthesis can result in a high mutation rate because:
A) alternative modified nucleotides can be incorporated more readily.

C) replication proceeds much faster than normal, resulting in many more mistakes.
D) the DNA polymerases involved cannot facilitate base-pairing as well as DNA polymerase III.
E) the DNA polymerases involved lack exonuclease proofreading activities.
