All proteins are made up of combinations of 20 different amino acids. The RNA code (like DNA) is written in just four different chemical 'letters' - bases. How can a code with four letters identify 20 different amino acids? By reading it three letters at a time - CAU, CAG, GGA, etc.
Â­DNA carrÂ­ies all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).Specifically, the order of nucleotides within a gene specifies the order and types of amino acids that must be put together to make a protein.A protein is made of a long chain of chemicals called amino acids Proteins have many functions: 1  Enzymes that carry out chemical reactions (such as digestive enzymes).pecifically, the order of nucleotides within a gene specifies the order and types of amino acids that must be put together to make a protein.
