Step-by-step 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.
