Question:
An arginine residue in a polypeptide chain sequence is designated by which of the following single letter codes?
An arginine residue in a polypeptide chain sequence is designated by which of the following single letter codes?
Show Hint
Distinctive Amino Acid 1-Letter Codes:
R = aRginine, K = Lysine, Y = tYrosine, W = tWiptophan, D = aspaDtic, E = glutEmic, N = asparagiNe, Q = Glutamine.
R = aRginine, K = Lysine, Y = tYrosine, W = tWiptophan, D = aspaDtic, E = glutEmic, N = asparagiNe, Q = Glutamine.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
IUPAC-IUBMB standardized single-letter amino acid notation.
Step 2: Detailed Explanation:
Single-letter codes for the given amino acids:
- A = Alanine
- N = Asparagine (AsN)
- R = Arginine (aRginine)
- Q = Glutamine (Q-tamine)
(Other distinctive codes: K = Lysine, W = Tryptophan, Y = Tyrosine, D = Aspartate, E = Glutamate).
Step 3: Final Answer:
Thus, arginine is designated by the single letter code R, matching option (C).
