What enzyme is unwinding the strands in transcription? Is it RNA Polmerase? I thought helicase unwound the strands. Then RNA Pol would read. My answer was incorrect though. So what, if any, role does helicase play in transcription?
Helicase still unwinds strands in prokaryotic transcription. The question is simply very picky about the order of events (since it is an ordering question) and wants you to realize that RNA Polymerase will bind to a promoter before any unwinding happens.
Thank you! My mistake, for some reason I thought helicase unwound the strand before RNA Pol landed. This cleared that up. Thanks again!
