DNA polymerase is an ENZYME that plays a key role in the replication of DNA. It is responsible for catalyzing the formation of new strands of DNA by joining nucleotides together. DNA polymerase is essential for the duplication of genetic material during cell division, and it is also involved in the repair of damaged DNA. The term DNA polymerase, e.g., refers to any ENZYME that catalyzes the polymerization of nucleotides into DNA.
