Genes provide the codes for proteins: structural proteins: the substances of your body, enzymes: control certain chemical reactions, dna: the blueprint. > dna is in the nucleus of every cell. > genes: provide the code for strings of amino acids. Amino acids: about 20 but can be combined in many ways to make proteins.
