During DNA replication, what enzyme is responsible for adding new nucleotides to the forming DNA strand a. DNA helicase b. DNA polymerase c. ligase d. RNA polymerase

The correct answer is b. DNA polymerase.<br /><br />During DNA replication, the enzyme responsible for adding new nucleotides to the forming DNA strand is DNA polymerase. DNA polymerase is an essential enzyme that catalyzes the addition of nucleotides to the growing DNA strand during replication. It reads the existing DNA strands and adds complementary nucleotides to form the new DNA strands.
