Explanation:

In DNA replication, first hydrogen - bonds between complementary bases break, causing DNA strands to unwind and expose bases. Then complementary nucleotides pair up with the exposed bases and hydrogen bonds form. Finally, nucleotides of the new DNA strand are enzymatically joined.

Answer:

1. Hydrogen bonds break between complementary bases.
2. DNA strands unwind to expose bases.
3. Complementary nucleotides pair up with exposed bases; hydrogen bonds form.
4. Nucleotides of new DNA strand are enzymatically joined.
