The two DNA strands are held together by hydrogen bonding between the bases on the different strands; therefore, all the bases are on the inside of the double helix, and the sugar-phosphate backbones are on the outside.

The two strands are held collectively via hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.

Covalent bonds arise inside every linear strand and strongly bond the bases, sugars, and phosphate groups (each within each thing and between additives).

Hydrogen bonds occur among the two strands and contain a base from one strand with a base from the second in complementary pairing.
