Promoters function
WebPromoters control the binding of RNA polymerase and transcription factors. Since the promoter region drives transcription of a target gene, it therefore determines the timing of gene expression and largely defines the amount … WebSep 2, 2024 · Promoters are usually found upstream from the start of transcription at the 5’end of where transcription starts. Promoters have to be in a 5’position near to the gene to be transcribed. The 5’end of DNA refers to the DNA strand that ends on a 5’carbon. Promoters are found in both prokaryotic cells and eukaryotic cells. Function:
