The rate of mRNA Transcription is regulated by the interaction of regulatory proteins that bind to DNA Sequences neat the PROMOTOR and modulate the rate at which the initation complex can form form on the promoter 9prcaryotes )
I eucaryotes transribtion factors MUST BIND to promoters to allow RNA Polymarase II to bind an dform initiation complex.
Specific transcrition fcators bind to regulatory DNA Sequences ofthen called ehnhancer or silencer sequences an dmodulate the formation on initiation complex -regulating the rate of transcription.
Ehnacers are funtional both downstreams and upstreams of the promotor site and in either orientation.
ASolencers contain specific bidning sites for specific transcription factors that inhibit transcription.
