A promoter is a specific region of DNA that initiates transcription of a particular gene, serving as a binding site for RNA polymerase and transcription factors. Promoters play a crucial role in regulating gene expression by determining when and how much of a gene product is produced, thereby influencing the overall cellular function. They are typically located upstream of the coding region of a gene and contain essential sequences that facilitate the binding of transcription machinery.
