Q. During transcription, the site of DNA molecule at which RNA polymerase binds is called

Q. During transcription, RNA polymerase first binds to which region of the transcription unit?

Q. In prokaryotes, holoenzyme RNA polymerase attaches to the DNA sequence at the promoter site of template DNA during transcription. The sequence of that point where the RNA polymerase binds is:
