an enzyme that catalyzes the formation of DNA from deoxyribonucleoside triphosphates. Cells contain several types of DNA polymerase, some of which are required for replication of DNA, and are indispensable for multipliation and division of cells.
Any of a group of enzymes that catalyze the formation of DNA strands from a DNA template.
An enzyme that can synthesize new complementary DNA strands using a DNA template and primer. Several of these enzymes are commercially available, including Taq DNA polymerase and rTth DNA polymerase.
