DNA is composed of nucleotides, which are composed of a 5-carbone sugar (deoxyribose), a phosphate, and a nitrogenous base (adenine, guanine, thymine, or cytosine abbreviated A, G, T, or C). DNA is composed of two complimetary strands, with complimentary bases matching up through hydrogen bonds. pairs with T, and C with G. DNA is not composed of amino acid or proteins, rather it serves as a set of instructions to combine amino acids into proteins (after it hads been transcribed into RNA the RNA is translated into amino acid sequences for proteins).
