Compared with DNA replication, transcription is _______ error prone because of differences in _______.
A) more; the number of copies made
B) more; the proofreading system
C) more; excision repair
D) less; the number of copies made
E) less; the proofreading system

Question

Quizplus · Accepted Answer

Transcription is more error prone than DNA replication because the proofreading systems in place for DNA replication are more robust and thorough than those for transcription. DNA polymerases involved in replication have proofreading capabilities that correct errors during the replication process, whereas RNA polymerases lack such extensive error-correcting mechanisms.
