Illustrate schematically the process of initiation, elongation, and termination during transcription of a gene in a bacterium.
During translation in bacteria, mRNA serves as a template, tRNA transports amino acids and reads the genetic information, and rRNAs serve as structural and catalytic components. There is a single DNA-dependent RNA polymerase that catalyzes the transcription of all types of RNA in bacteria. RNA polymerase connects to the promoter and starts transcription (Initiation). It also helps the helix open and continues elongation in some way. The nascent RNA, as well as the RNA polymerase, falls off once the polymerases approach the terminator region. This results in termination.
