Match the items in Group I with Group II:
Group I
P. Circular dichroism
Q. X-ray crystallography
R. Freeze-drying
S. Ultracentrifugation
Group II
1. Concentration
2. Sedimentation coefficient
3. Secondary structure determination
4. Tertiary structure determination
Options:
(A) P-4, Q-1, R-2, S-3
(B) P-1, Q-4, R-3, S-2
(C) P-2, Q-3, R-4, S-1
(D) P-3, Q-4, R-1, S-2
Answer
Answer: (D) P-3, Q-4, R-1, S-2
Explanation: Circular dichroism is used for secondary structure determination (3). X-ray crystallography is used for tertiary structure determination (4). Freeze-drying involves concentration (1). Ultracentrifugation measures sedimentation coefficient (2).
