What is the primary role of DNA polymerase in cellular processes?

The primary role of DNA polymerase is to synthesize new DNA strands during the process of DNA replication. This enzyme plays a crucial role in copying the genetic information contained within the DNA before a cell divides. Each strand of the original DNA molecule serves as a template for the formation of a new complementary strand, which is essential for ensuring that the genetic information is accurately passed on to daughter cells.

During replication, DNA polymerase adds nucleotides one by one to the growing DNA strand, matching each nucleotide to its complementary base on the template strand. This activity not only allows for the duplication of the genetic material but also includes a proofreading capability, which ensures that any errors in base pairing are corrected, maintaining the integrity of the genetic code. Thus, DNA polymerase is fundamental to both the accurate replication of DNA and the transmission of genetic information.
