An enzyme which catalyses the synthesis of DNA using a single DNA strand as a template. The polymerase copies the template in the 5′-3’direction provided that sufficient quantities of free nucleotides, dATP and dTTP are present.
An enzyme that catalyzes the assembly of nucleotides into RNA (RNA polymerase) and of deoxynucleotides into DNA (DNA polymerase).
Enzyme that facilitates the synthesis of RNA or DNA from a template strand during replication.
An enzyme that catalyzes polymerization of nucleotides to form DNA molecules before cell division, or RNA molecules before protein synthesis.
