DNA polymerase
Quick Summary
DNA polymerase is an enzyme crucial for DNA replication and repair. It functions by synthesizing new DNA strands using an existing DNA molecule as a template. This process ensures the accurate duplication of genetic information and the repair of any damaged DNA segments.12
The enzyme catalyzes the addition of nucleotide triphosphates to the growing DNA chain, with the specific nucleotide selected based on the complementary base in the template strand. This mechanism requires the presence of all four deoxyribonucleoside triphosphates and a pre-existing DNA template.2

…replication, a complex enzyme called DNA polymerase moves along the DNA molecule, pairing nucleotides on each template strand with free complementary nucleotides. Because of the antiparallel nature of the DNA strands, new strand synthesis is different on each template. On the 3′ → 5′ template strand, polymerization proceeds in the…
