Hydrogen bonds can form with bases on the opposite DNA strands in the double helix, or between the bases and H2O in the single stranded conformation. Considering that the double helix is the most stable conformation in water, how does this observation support the conclusion that base stacking contributes more to helix stability than interbase hydrogen bonding?
