WebIn bacteria, elongation begins with the release of the σ subunit of the RNA polymerase holoenzyme. The dissociation of σ allows the core enzyme to proceed along the DNA template, synthesizing mRNA in the 5' to 3' direction at a rate of approximately 40 nucleotides per second. 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 … how do you say scholarship in spanishWebDec 24, 2024 · In bacteria, transcription and translation are capable of proceeding simultaneously.
