Answer #1

Ans) The correct answer is "7" i.e all of the above

(Quaternary structure consists of 2 or more polypeptide chains joined via bonds like ionic bonds,hydrogen bonds,van der waals forces etc for their stabilization and correct folding.Disulfide linkages can also be found in the quaternary structure of the protein.Hydrogen bonds forms bonds between polar R or side chain groups,disulfide bond is formed in between two cysteine residues and is the strong bond,peptide bond is formed between two amino acud residues.So,all of these bonds are essential for the protein function and to fold them in native configuration).
