Here's a breakdown:
* DNA polymerase reads the existing DNA strand (template strand) and uses it as a guide to add complementary nucleotides to the new strand.
* It moves along the template strand, adding nucleotides one at a time to the 3' end of the new strand, following the base pairing rules (A with T, C with G).
* This process is known as DNA replication, where a new, identical copy of the DNA molecule is created.
There are different types of DNA polymerases involved in various aspects of DNA replication, repair, and other processes, but they all share this fundamental function of adding nucleotides to a growing DNA strand.
