Describe the process of transcription in bacteria
Transcription has three steps—initiation, elongation, and termination.
RNA polymerase binds with the promoter to initiate the process of transcription. Association with the initiation factor (σ) alters the specificity of RNA polymerase to initiate transcription.
RNA polymerase uses nucleoside triphosphate as the substrate, and polymerisation occurs according to complementarity.
Termination occurs when the termination factor (rho) alters the specificity of RNA polymerase to terminate transcription. As the RNA polymerase proceeds to perform elongation, a short stretch of RNA remains bound to the enzyme. As the enzyme reaches the termination region, this nascent RNA falls off and transcription is terminated.
