Question

Name the factors for RNA polymerase enzymes which
recognize the start and termination signals on DNA for
transcription process in Bacteria

Anshul Ruhela · Accepted Answer

Dear Student,
RNA polymerase is only capable of catalysing the process of
elongation It associates transiently with initiation-factor
(σ) and termination-factor (ρ) to initiate and terminate
the transcription Association with these factors alter the
specificity of the RNA polymerase to either initiate or
terminate
Initiation-factor (σ) or sigma is a protein and
transcription initiation factor It enable RNA polymerase binding to
the promoter Different types of sigma factors are specific for
transcribing different genes
A ρ factor (Rho factor) is a prokaryotic protein required to
release the newly made (nascent) RNA from transcription complex
