Part
A
The sigma (?) subunit binds to the core RNA polymerase
enzyme. The function of this sigma factor is to recognize and bind
to the promoter of a gene so that transcription can be initiated.
The closeup shows the secondary structure of the sigma (?)
subunit, which consists of four domains. Identify the domains
labeled 1-3.
