Translation is the process by which the genetic code contained within a messenger RNA (mRNA) molecule is decoded to produce a specific sequence of amino acids in a polypeptide chain. It occurs in the cytoplasm following DNA transcription and, like transcription, has three stages: initiation, elongation, and termination. chiswick vwWebInfo. Promoters are DNA sequences located in the 5' region adjacent to the transcriptional start site. RNA polymerase and accessory proteins (transcription factors) bind to the promoter to initiate production of an mRNA transcript. Interactions of proteins at the promoter regulate gene actvity by activating or repressing transcription. chiswick walk chelmsley wood
