In other words, DNA polymerase is an enzyme that synthesizes a product by interpreting the existing DNA strand as a template and produces the complementary sequence of the template into a new strand. 3. DNA polymerases necessitate the presence of a primer to start synthesis.The reaction catalyzed by DNA polymerases that works to elongate the chain is a nucleophilic attack by the 3âOH terminus of the growing chain on the innermost phosphorus atom of the deoxynucleotide triphosphate.Therefore, a primer strand with a free 3'-OH group must be bound to the template strand from the start.he reaction catalyzed by DNA polymerases that works to elongate the chain is a nucleophilic attack by the 3âOH terminus of the growing chain on the innermost phosphorus atom of the deoxynucleotide triphosphate.

Quick Answer. DNA polymerases is the enzyme that catalyzes DNA synthesis, but it is different from RNA polymerases. This particular type of polymerases have specific conditions and requirements that must be met for them to be produced. Without these enzymes, the nucleotides that are the building blocks of DNA cannot be made.
