nucleotide sequence within an
operon, lying between the
operator and the
structural gene or genes, that serves as a recognition site and point of attachment for the
RNA polymerase. It is the starting-point for
transcription of the structural gene or genes in the operon, but is not itself transcribed.

views updated Jun 08 2018promoter (in protein synthesis) The region of a DNA molecule that signals the start of
transcription. In eukaryote genes, the promoter typically has a core promoter very near to the transcription start site, often containing the base sequence TATA (hence it is called the
TATA box). Other promoter elements are located ‘upstream’ of the core promoter and start site. Proteins called
transcription factors bind to the promoter and ensure that the enzyme responsible for transcription, RNA
polymerase, is correctly positioned with respect to the coding region of the gene.
