What is the function of the sigma subunit (factor) of E. coli RNA polymerase in transcription? addition of a 5' cap formation of phosphodiester bonds using ribonucleotide triphosphates recognition of termination nucleotide sequence recognition of initiation sites or promoters DNA degradation necessary for the initiation step

Step 1
coli RNA polymerase plays a crucial role in transcription. It is not involved in the addition of a 5' cap, as this process occurs in eukaryotic cells, not in bacteria like E. coli. It also does not form phosphodiester bonds, as this is the function of the core RNA Show more…
