what are the enzymes that catalyze the synthesis of new DNA called
DNA polymerases are a family of enzymes that carry out all forms of DNA replication. DNA polymerases in general cannot initiate synthesis of new strands, but can only extend an existing DNA or RNA strand paired with a template strand.To begin synthesis, a short fragment of RNA, called a primer, must be created and paired with the template DNA strand.NA polymerase adds a new strand of DNA by extending the 3' end of an existing nucleotide chain, adding new nucleotides matched to the template strand one at a time via the creation of phosphodiester bonds.
