It catalyzes the formation of phosphodiester bonds using NTPs as substrates. It coordinates synthesis of the leading strand and the lagging strand. It functions as a holoenzyme that polymerizes in the 3’→ 5’ direction. It uses an exonuclease activity to remove incorrect nucleotides.DNA polymerases have a shape resembling a right hand with three domains. Explain how these three domains participate during DNA synthesis.
