Base Stacking Interactions

Base stacking interactions refer to the non-covalent attractive forces between the aromatic rings of nucleotides. These interactions involve van der Waals forces and hydrophobic effects, where the planar structures of the bases overlap, reducing their exposure to water and stabilizing the DNA double helix. This stacking provides additional thermodynamic stability to the structure beyond what is contributed by hydrogen bonds between complementary bases.
