Checking my knowledge of proteins and polypeptide chains? ?
Hello, is this correct?
Amino acids are composed of an amino group, a carbon, a hydrogen, an R variable group, and a carboxyl group. A polypeptide chain is a chain of amino acids held together by peptide bonds. Enzymes/proteins can be made of many different polypeptide chains. One gene codes for one polypeptide chain, many different genes code for different polypeptide chains that form enzymes and proteins.
