What are bacterial promoters? A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. Thus the promoter region controls when and where in the organism your gene of interest is expressed. How do you identify a promoter? To find the promoter region, use Map Viewer to locate the gene within a chromosomal context. Then increase the value of the coordinates that surround the gene to a larger sequence that includes the promoter. How are promoters defined? A promoter...
