- A Hydrolytic cleavage of the covalent peptide bonds linking amino acid residues
- B Loss of 3D structure without breaking peptide bonds
- C Condensation reactions forming additional peptide bonds within the chain
- D De novo synthesis of new amino acid monomers from precursor molecules
Correct answer: B. Loss of 3D structure without breaking peptide bonds
Explanation: Denaturation disrupts secondary and tertiary structure (breaking H bonds, hydrophobic interactions, disulfide bonds) but does NOT break peptide bonds of the primary structure.
