Step 1: Denaturation Levels — Denaturation typically disrupts higher-order folding, as the non-covalent interactions break down.
Step 2: Identifying Survival — The , , and structures are all dependent on these secondary forces and thus change during denaturation.
Step 3: Conclusion — The covalent backbone of amino acids (primary structure) remains intact. Correct option is (a).
Remember: Irreversible denaturation, like cooking an egg, changes its physical state permanently.
