The DNA double helix has two types of bonds, covalent and hydrogen. Covalent bonds exist within each linear strand and strongly bond bases, sugars, and phosphate groups (both within each component and between components). The nucleotides in a strand of DNA are held together by phosphodiester bonds (a specific type of covalent bond). The two strands of DNA are held together by hydrogen bonds that form between the nitrogenous bases in one strand and the nitrogenous bases in the other strand. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
