Hydrogen bonds form between the base pairs. The number of bonds between the base pairs differs; G-C pairs have three bonds, and A-T pairs have only two. Every DNA molecule has hundreds of thousands of base pairs, and each base pair has multiple bonds, so the rungs of the ladder are very strongly bonded together.

Expert Answers. DNA consists of polymeric chains of nucleotides. A nucleotide consists of three parts, a phosphate group, a deoxyribose sugar ring, and a nitrogenous base. The phosphate and ribose are really present simply to act as a backbone for the double helix. So a covalent bond is really important here for purposes of rigidity and strength.

If you liken the covalent bond between the oxygen and hydrogen to a stable marriage, the hydrogen bond has "just good friends" status. Water as a "perfect" example of hydrogen bonding. Notice that each water molecule can potentially form four hydrogen bonds with surrounding water molecules.

In a DNA double helix, two polynucleotide strands come together through complementary pairing of the bases, which occurs by hydrogen bonding. Each base forms hydrogen bonds readily to only one other — A to T and C to G — so that the identity of the base on one strand dictates what base must face it on the opposing strand.

Both DNA and RNA are known as nucleic acids. The nitrogen bases are pyrimidine in structure and form a bond between their 1' nitrogen and the 1' -OH.

Legend: DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases. The bases are adenine (A), thymine (T), cytosine (C) and guanine (G).
