Observe: Drag the yellow DNA polymerase molecule onto the DNA strand.
DNA polymerase adds complementary nucleotides to create new double-stranded DNA molecules.
Step 1: Help the DNA polymerase complete the right DNA strand by adding nucleotides according to base pairing rules.
Step 2: Help the DNA polymerase complete the left DNA strand by adding nucleotides according to base pairing rules.
