What is the function of DNA polymerase?

The primary function of DNA polymerase is to synthesize new DNA strands during the process of DNA replication. During replication, DNA polymerase adds nucleotides to a growing DNA strand complementary to the template strand, ensuring accurate duplication of the genetic material. This enzymatic activity is essential for cell division, allowing genetic information to be passed on to daughter cells.

DNA polymerase also has proofreading capabilities, meaning it can recognize and correct errors that occur during the synthesis of DNA. This enhances the overall fidelity of DNA replication, preventing mutations and ensuring the integrity of the genetic information.

While DNA polymerase is involved in DNA synthesis and error correction, its specific role does not include repairing mutated DNA sequences, transporting RNA, or decoding mRNA into proteins, which are functions associated with other cellular processes and enzymes.
