The two polynucleotide chains that comprise each molecule of deoxyribonucleic acid, or DNA, are held together by two forces: hydrogen bonding and hydrostatic forces. Hydrogen bonds form between complementary base pairs, while hydrostatic forces determine the orientation of the hydrophilic phosphate backbone relative to the more hydrophobic base pairs. Each polynucleotide chain is comprised of a negatively charged phosphate backbone that connects a sequence of base pairs.
