The major interaction stabilizing the double helical structure of DNA is the favorable charge-charge interactions between the two strands. covalent bonds that crosslink the two strands. hydrogen bonding between backbone atoms on opposite DNA strands. van der Waals interactions between the stacked bases of the double helix. hydrogen bonds between bases on opposite DNA strands.
