JEE MAIN - Chemistry (2023 - 8th April Evening Shift - No. 10)

Match List I with List II

LIST I
Natural amino acid
LIST II
One letter code
A. Glutamic acid I. Q
B. Glutamine II. W
C. Tyrosine III. E
D. Tryptophan IV. Y

Choose the correct answer from the options given below:

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

Explanation

The one-letter code for each amino acid is as follows:

Glutamic Acid (A) is represented by the letter E (III).

Glutamine (B) is represented by the letter Q (I).

Tyrosine (C) is represented by the letter Y (IV).

Tryptophan (D) is represented by the letter W (II).

These one-letter codes are part of the standard notation used in biology and biochemistry to represent the 20 standard amino acids, plus a few others. The codes are designed to be short and easy to remember, while still being distinct from each other.
