Answer
The increased stability of DNA is due to the presence of hydrogen bonds, hydrophobic, and van der Waals interactions between the complementary bases stacked on the inner helix.
Work Step by Step
DNA has increased stability when compared to RNA. It acts primarily as an archive of information in the form of base sequences. The increased stability of DNA is due to the presence of hydrogen bonds, hydrophobic, and van der Waals interactions between the complementary bases stacked on the inner helix.
