The protein-DNA interactions that control whether or not a gene is accessible to RNA polymerase occur during which phase of gene expression?
A) Replication
B) Transcription
C) Translation
D) Replication and transcription
E) Transcription and translation

Question

Quizplus · Accepted Answer

Protein-DNA interactions that control gene accessibility occur during transcription, as RNA polymerase binds to the DNA template and reads it to create an mRNA copy. Replication occurs prior to transcription, while translation occurs after the mRNA has been transcribed. Therefore, choices A, C, D, and E can be eliminated.
