Question

Match LIST-I with LIST-II
\begin{tabularx}{0.8\textwidth}{|l|X|l|X|} \hline \multicolumn{2}{|c|}{LIST-I} & \multicolumn{2}{c|}{LIST-II}
\multicolumn{2}{|c|}{Name of the amino acid} & \multicolumn{2}{c|}{One letter abbreviation/name}
\hline A. & Methionine & I. & D
B. & Aspartic acid & II. & K
C. & Lysine & III. & E
D. & Glutamine & IV. & M
\hline \end{tabularx}
Choose the correct answer from the options given below:

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

Hint:

For amino acids whose names don't start with a unique letter, the codes can be tricky. Memorize these: Aspartic Acid (D), Glutamic Acid (E), Asparagine (N), Glutamine (Q), Phenylalanine (F), Tyrosine (Y), Tryptophan (W), Lysine (K).

Answer 1

The Correct Option is B

Step 1: Concept Explanation:
The task is to associate standard amino acids with their corresponding one-letter abbreviations, a crucial skill for interpreting protein sequences.

Step 2: Detailed Matching:
- A. Methionine: Encoded as M. Therefore, A corresponds to IV.
- B. Aspartic acid: Encoded as D. Therefore, B corresponds to I.
- C. Lysine: Encoded as K. Therefore, C corresponds to II.
- D. Glutamine: Typically encoded as Q. However, LIST-II contains E, the code for Glutamic acid. A likely error exists; "Glutamine" in LIST-I should probably be "Glutamic acid." Assuming this correction, Glutamic acid is encoded as E. Therefore, D corresponds to III.

Step 3: Solution:
Applying standard abbreviations and correcting the likely error, the correct matches are A-IV, B-I, C-II, D-III, which is option (B).
