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: Understanding the Concept:
The question requires matching standard amino acids with their universally accepted one-letter abbreviations. These are essential to know for reading protein sequences.

Step 2: Detailed Matching:
- A. Methionine: The one-letter code is M. Thus, A matches with IV.
- B. Aspartic acid: The one-letter code is D (from asparDic). Thus, B matches with I.
- C. Lysine: The one-letter code is K (as L is taken by Leucine, K is the preceding letter). Thus, C matches with II.
- D. Glutamine: The one-letter code is Q (pronounced 'Q-tamine'). However, Q is not in LIST-II. LIST-II has E, which is the code for Glutamic acid. There appears to be a typo in the question, with "Glutamine" in LIST-I likely intended to be "Glutamic acid". Assuming this correction, Glutamic acid's code is E (from glutamEc). Thus, D matches with III.

Step 3: Final Answer:
Based on the standard codes and correcting for the likely typo, the matches are A-IV, B-I, C-II, D-III. This combination corresponds to option (B).
