What is not true regarding Quaternary structure of protein a) It involves the clustering of several individual peptide or protein chains into a final specific shape. b) Removing the protein subunits can still maintain functionality of respective subunits c) All type of bonds such as hydrogen bonds, ionic bonds, hydrophobic interactions and disulfide bridges play a role d) Quaternary structure involves assembly of same kind of protein subunits

The arrangement of many polypeptide chains or subunits into a functional, multi-subunit complex defines a protein's quaternary structure. Which of the following statements about the quaternary structure of proteins is accurate? The beta chain direction in a protein's primary structure is the only factor that determines its quaternary structure Regardless of size or purpose, all proteins have their quaternary structure Quaternary structure involves the non-covalent interactions and spatial arrangement of multiple polypeptide chains Quaternary structure is only relevant when it comes to enzymes and has no role in structural/transport proteins

What is the quaternary structure of a protein?Group of answer choicesIt is 3D arrangement of localized regions of a protein.It is a shape adopted by two or more folded polypeptide chains.It is 3D shape adopted by the entire polypeptide chain.It is the sequence of amino acids joined together by amide bonds.
