DNA Polymerase is the enzyme which adds new nucleotides during  replication.
- Primary enzyme involved in transcription is RNA polymerase: catalyzes the formation of the phosphodiester bonds that link the nucleotides and form the sugar-phosphate backbone of the RNA chain; hydrolysis of ribonucleotides (rNTPs) and the release and breakdown of pyrophosphate to two inorganic phosphates is the energy that drives transcription.
