Question

Match the LIST-I with LIST-II

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

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Amino acids are often represented by three-letter and one-letter symbols. They are also categorized as "essential" (cannot be synthesized by the body) or "non-essential" (can be synthesized).

Step 2: Key Formula or Approach:
1. Identify the one-letter codes: Arginine (R), Aspartic acid (D), Lysine (K), Glutamic acid (E). 2. Basic amino acids like Lysine and Arginine are typically essential. Acidic amino acids like Aspartic and Glutamic acid are non-essential.

Step 3: Detailed Explanation:
1. Arginine: One letter symbol is R. It is considered semi-essential but generally grouped with essential amino acids for these matching sets. (A-II) 2. Aspartic acid: One letter symbol is D. It is non-essential. (B-I) 3. Lysine: One letter symbol is K. It is an essential amino acids. (C-IV) 4. Glutamic acid: One letter symbol is E. It is non-essential. (D-III)

Step 4: Final Answer:
The matching sequence is A-II, B-I, C-IV, D-III.
