Alternative s factors make complexes with the core polymerase to direct the new holoenzyme to a particular set of promoters that differ in sequence from the general E. coli promoter sequence. Thus the polymerase can be directed to trancribe a new set of genes.

WebThe process of gene expression involves two main stages: Transcription Translation Transcription The production of messenger RNA (mRNA) by the enzyme RNA polymerase, and the processing of the resulting mRNA molecule. Translation The use of mRNA to direct protein synthesis, and the subsequent post-translational processing of the protein molecule.
