The four building blocks of DNA are the nucleotides A, T, G, C. Each nucleotide is composed of a sugar-phosphate covalently linked to a base. The nucleotides are covalently linked together into polynucleotide chains, with a sugar-phosphate backbone. In a DNA molecule, one strand of this runs from 5' to 3' and the other from 3' to 5'.
