Answer:
Explanation:
Sigma factors bind to Ribonucleic acid polymerase (RNAP) which are required for bacterial RNA polymerase to recognize promoters. Bacteria have several types of sigma factors this is activated during different conditions.
Sigma factor identifies different classes of promoters and direct or regulate transcription to specific cellular programs they are called housekeeping sigma factor.
A mutation in sigma factor will affect transcription of bases this is because it binds with RNAP to initiate transcription of base sequence that should be moved to ribosome where it will be translated into an amino acid. This will further affect the growth of the bacteria.
