Question

Match the following:

List - I	List - II
A. Nucleic acids structure	IV. Phosphorous
B. Synthesis of nucleic acid	III. Iron
C. Stabilize protein structure	II. Sulphur
D. Catalase	II. Sulphur

• A. A-I, B-IV, C-II, D-III
• B. A-V, B-I, C-II, D-III
• C. A-IV, B-V, C-II, D-III
• D. A-IV, B-I, C-II, D-III

Hint:

For match-the-following, first establish clear roles of each element in biological functions. Eliminate distractors using known pairings.

Answer 1

The Correct Option is D

A. Nucleic acids structure — IV. Phosphorous: Phosphorus is a key element in nucleotides and thus in the structure of nucleic acids.
B. Synthesis of nucleic acid — I. Magnesium: Magnesium ions are essential cofactors for enzymes involved in nucleic acid synthesis.
C. Stabilize protein structure — II. Sulphur: Sulphur helps in forming disulfide bridges, which stabilize protein structure.
D. Catalase — III. Iron: Iron is a component of catalase, which is an iron-containing enzyme.
