The correct order of events at the promoter during transcription initiation in bacteria involves the formation of a closed complex (where RNA polymerase binds to the promoter DNA without unwinding it), followed by the transition to an open complex (where the DNA is unwound to allow template strand access), and finally, transcription initiation occurs.
