Question

Match the amino acid given in List-I with their one-letter code given in List-II 
\[ \begin{array}{|l|l|} \hline \textbf{Name of amino acid} & \textbf{One-letter code} \\ \hline (A) \; \text{Lysine} & (I) \; W \\ \hline (B) \; \text{Tryptophan} & (II) \; Q \\ \hline (C) \; \text{Tyrosine} & (III) \; K \\ \hline (D) \; \text{Glutamine} & (IV) \; Y \\ \hline \end{array} \]

• (A) - (II), (B) - (I), (C) - (III), (D) - (IV)
• (A) - (III), (B) - (I), (C) - (II), (D) - (IV)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Memorize the one-letter codes for amino acids to quickly identify them in protein sequences.

Answer 1

The Correct Option is B

Step 1: Understanding the one-letter codes.
Each amino acid has a specific one-letter code. Here is the correct mapping:
Step 2: Correct matching of amino acids with their codes.
- Lysine (A): The one-letter code for Lysine is K.
- Tryptophan (B): The one-letter code for Tryptophan is W.
- Tyrosine (C): The one-letter code for Tyrosine is Y.
- Glutamine (D): The one-letter code for Glutamine is Q.
Step 3: Conclusion.
The correct matching is: (A) - (III), (B) - (I), (C) - (II), (D) - (IV).
Final Answer: \[ \boxed{\text{The correct answer is (2) (A) - (III), (B) - (I), (C) - (II), (D) - (IV).}} \]
