Promoter

A short promoter region highlighted on double-stranded DNA, shown either as a short double helix fragment, helical ribbon, or straight schematic DNA segment. The promoter appears immediately upstream of a gene or near the transcription start site and is visually distinct from adjacent DNA as a contrasting colored band, narrow box, block, bracket, boxed sequence, or labeled patch. Clean schematic styling should clearly identify it as a regulatory binding site for RNA polymerase or other transcription machinery, and some versions may include a directional arrow indicating transcription initiation or orientation relative to the nearby coding region.
