When RNA polymerase binds to a sigma to create a holoenzyme and the sigma guides the RNA polymerase to certain locations where transcription should begin

The holoenzyme is made up of a core enzyme (RNA polymerase) and a detachable protein subunit called a sigma. The holoenzyme creates an enviroment in which the sigma guides the RNA polymerase to the site where transcription should take place. The locations where the sigma guides the RNA pol are called promoters.
