REVIEW for EXAM4-May 12th
... Transcription initiates at the promoter region which is just upstream of the transcription start site. The minimal promoter region contains the essential DNA binding elements which attract a protein complex of the basic transcriptional machinery that ‘pile ups’ close to the start transcription start ...

The Operon - dl.edi
... Absence of the lac repressor is essential but not sufficient for effective transcription of the lac operon. The activity of RNA polymerase also depends on the presence of another DNAbinding protein called catabolite activator protein or CAP. Like the lac repressor, CAP has two types of binding sites ...
