Question

multiple choice question
what does the quaternary structure of a protein depend upon?
sequence of amino acids
interactions of hydrophobic residues within a polypeptide
interactions between multiple polypeptide chains
hydrogen bonding between nearby amino acids within a polypeptide chain

Explanation:

The quaternary structure of a protein is formed by the interactions between multiple polypeptide chains. The sequence of amino - acids determines primary structure. Hydrophobic interactions within a polypeptide mainly relate to tertiary structure. Hydrogen bonding between nearby amino acids within a polypeptide chain is important for secondary structure.

Answer:

C. Interactions between multiple polypeptide chains
