Mechanisms of Microbial Transcription

Bacterial transcription is the method by which bacteria transcribe genetic information encoded in their genome into carrier ribonucleic acid (mRNA) molecules. mRNA is then employed as a template for the generation of bacterial proteins.

Bacterial transcription is the process in which a section of bacterial DNA is drawn into a newly incorporated strand of messenger RNA (mRNA) with the use of the enzyme RNA polymerase. Once the σ-factor releases from the polymerase, elongation proceeds.

Transcription is brought out by a molecular machine called "RNA polymerase," which is highly conserved in order, structure, and function from bacteria to humans. Control of the activity of RNA polymerase is the central node and can occur at various steps of the transcription cycle. In modern years, research on microbial transcription has extended swiftly due to new atomic-level structures of RNA polymerases and their corresponding transcription factors as well as systems-wide profiling of gene regulatory events.
