Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(III), (B)-(I), (C)-(IV), (D)-(II)

The correct answer is (2).

Match List-I with List-II

(A) Denaturation: Denaturation is the process of unfolding of the secondary, tertiary and quaternary structure of a protein, while the primary structure remains intact. So, denaturation is matched with (III).

(B) Primary structure of protein: The primary structure of a protein is the sequence of amino acids in the protein chain. So, the primary structure of protein is matched with (I).

(C) Quaternary structure of protein: The quaternary structure of a protein is the spatial arrangement of subunits (containing 2 or more polypeptide chain) with respect to each other. So, the quaternary structure of protein is matched with (IV).

(D) Secondary structure of protein: The secondary structure of a protein is the regular folding of the polypeptide chain into α-helices, β-pleated sheets, or turns. So, the secondary structure of protein is matched with (II).
