WebThe maltose operon is an example of a positive control of transcription. When maltose is not present in E. coli, no transcription of the maltose genes will occur, and there is no maltose to bind to the maltose activator protein. This prevents the activator protein from binding to the activator binding site on the gene, which in turn prevents RNA polymerase from binding to … Web1 Feb 2024 · Dual binding sites can be found in operons with several promoters close together, indicating that one site can activate one promoter while repressing another . The promoter arrow in this graphical output is linked with its detailed information, including gene name, +1 site, sigma factor, distance from the start site, keynote, evidence and references.
