WebTranscription and Gene Regulation. RNA polymerase is the enzyme complex that makes an RNA chain from a double-stranded (or single-stranded) DNA template. RNA polymerase in E. coli is composed of 2 α subunits, 1 β subunit containing the catalytic activity, 1 β’ subunit that has DNA binding activity, and a δ subunit. WebDNA polymerase I also has 3' to 5' and 5' to 3' exonuclease activity, which is used in editing and proofreading DNA for errors. The 3' to 5' can only remove one mononucleotide at a time, and the 5' to 3' activity can remove mononucleotides or up to 10 nucleotides at a time. E. coli types.
