DNA polymerase is a vital enzyme responsible for synthesizing new strands of DNA during the process of DNA replication. Its main role is to add complementary nucleotides—adenine (A), thymine (T), cytosine (C), and guanine (G)—to the growing DNA strand, following the sequence of the original template. This ensures that the genetic information is copied accurately before a cell divides. The enzyme moves along the template strand in the 3′ to 5′ direction, while synthesizing the new strand in the 5
