C) the core polymerase plus two alpha subunits, two beta subunits, and a sigma subunit. D) the core polymerase plus a sigma subunit. E) two alpha subunits, two beta subunits, and two sigma subunits. How does DNA polymerase differ from RNA polymerase? A) Only RNA polymerase adds new nucleotides to the 3' end of a growing chain. B) Only RNA polymerase requires a primer. C) Only DNA polymerase uses a template DNA strand to direct the synthesis of a new nucleotide strand. D) Only DNA polymerase has a proofreading ability.
