Replication of DNA occurs before cell division. This is because, in order for cells to divide, they must first duplicate all of their DNA so that each new cell will have a complete set of genetic instructions. This process is known as DNA replication.

Here are the steps of DNA replication:

1. Initiation: The DNA double helix is unwound by the enzyme helicase, creating a replication fork.

2. Elongation: New strands of DNA are synthesized by the enzyme DNA polymerase. The new strands are complementary to the original strands, meaning that for every A on the original strand, a T is added to the new strand, and vice versa. Similarly, for every C on the original strand, a G is added to the new strand, and vice versa.

3. Termination: Once the entire DNA molecule has been replicated, the process is terminated. The two new DNA molecules each contain one original strand and one new strand
