<h3>Duplication requires the separation of complementary DNA strands to allow for DNA replication. </h3>
Explanation:
Several interacting forces such as Vanderwaal's forces, hydrophobic interaction and hydrogen bonds stabilize the DNA double helix structure.The strands of DNA double helix are held together by the hydrogen bond between the corresponding nucleotide bases. The separation of complimentary strands occur during replication because breaking the hydrogen bonds are comparatively easier than breaking any other bond stabilizing the DNA double helix.
