Promoters contain specific sequences that are recognized by transcription factors and RNA polymerase. These sequences include: 1. Core Promoter: This region contains the TATA box and other elements necessary for the binding of RNA polymerase. 2. Proximal Promoter: Located just upstream of the core promoter, it contains binding sites for transcription factors that enhance or repress transcription. 3. Distal Promoter: Further upstream, this region includes enhancers and silencers that further regulate gene expression.
