Proofreading by DNA polymerase must occur before the end of ____ to prevent mistakes from becoming mutations.
A)cell division
B)chromatid duplication
C)transcription
D)translation
E)DNA replication

Question

Quizplus · Accepted Answer

Proofreading by DNA polymerase checks for errors in base pairing during DNA replication. If mistakes are not corrected before replication is complete, they can become permanent mutations in the genome. The other choices listed do not directly involve DNA polymerase proofreading. Transcription involves the synthesis of RNA from DNA, while translation involves the synthesis of proteins from RNA. Chromatid duplication occurs before cell division, but proofreading occurs during DNA replication.
