    1. DNA uncoils and the two strands unzip. The hydrogen bonds between the base pairs break and the two strands of the DNA separate.

    2. Free nucleotides move in and bind with the parent DNA strands (the DNA template). Complementary bases bind to the open bases on the template strands. 

    3. The free nucleotides in the new strands bind together. The copied DNA recoils. The two DNA molecules are identical.

    4. The structure of the DNA molecule (two complementary strands that can separate between the base pairs) ensures that the DNA is copied efficiently (quickly and correctly).
