What do bacterial promoters help provide in the grand scheme

What do bacterial promoters help provide in the grand scheme of transcription?

specificity of transcription

frequency of transcription

primer binding to initiate transcription

specificity and frequency of transcription

specificity and frequency of transcription and primer binding to initiate transcription

Solution

Promoter sequences are DNA sequences that start the transcription of a gene at a particular site by the enzyme RNA polymerase begins. They are upstream or at the 5\' end so they control the primer binding to initiate transcription. Hence the option c: primer binding to initiate transcription is correct.
