Introduction 

Proteins are made of long chains of smaller subunits called amino acids. There are 20 different types of amino acids found in proteins, and the specific sequence of amino acids determines the protein's three-dimensional structure and its specific function. The sequence of amino acids is determined by the genetic code, which is stored in the DNA molecule.
