Quaternary structure of protein is:: (A) The arrangement sequence of amino acids in the polypeptide chain, (B) Inter relation between amino acids in a single polypeptide chain, (C) Inter relation of amino acid in 2 polypeptide chains, (D) The inter relation and arrangement of polypeptides in a protein with more than 2 polypeptides chains
Answer is D. Ans. D. The inter relation and arrangement of a polypeptides in the protein with more than 2 polypeptides chains)a. Protein that contain two or more polypeptide chains associated by non-covalent forces are said tob. exhibit quaternary structure.c. The arrangement sequence of amino-acids in the polypeptide chain -- is primary structure of protein.d. Inter relation of amino-acids in polypeptide chain is -- secondary structure.
