There are twenty different types of amino acids.Transfer RNA molecules carry the amino acids to the ribosome.The messenger RNA is read three bases at a time. As each triplet is read, a transfer RNA delivers the corresponding amino acid.This is added to a growing chain of amino acids.Once the last amino acid has been added, the chain folds into a complex 3D shape, to form the protein.
