Who found the three letter code words for each amino acid?
Dr. Margaret Oakley Dayhoff, arguably the founder of the field of bioinformatics, shortened the code from the three letter designations to the single letter code in an effort to reduce the size of the data files needed to describe the sequence of amino acids in a protein.

What are the codes for amino acids?
Multiple codons can code for the same amino acid. The codons are written 5′ to 3′, as they appear in the mRNA. AUG is an initiation codon; UAA, UAG, and UGA are termination (stop) codons.
How do you remember the 20 amino acids?
Here is a mnemonic to help you remember that: OH no, a STY! The amino acids that contain an -OH group are serine, threonine, and tyrosine, and their one letter abbreviations are S, T, and Y.
What is the 13th amino acid?
A 13-amino acid peptide was identified in three glycosyltransferases of the yeast endoplasmic reticulum. These enzymes, the products of the ALG1, ALG7, and DPM1 genes, catalyze the transfer of sugars from nucleotide sugars to dolichol phosphate derivatives.
What does the 3 letter code Glu represent?

| GGT | Glycine | Gly |
| GGC | Glycine | Gly |
| GGA | Glycine | Gly |
What amino acid does CAG code for?
amino acid glutamine
For example, the codon CAG represents the amino acid glutamine, and TAA is a stop codon.
What amino acid is CAG?
Glutamine
Codon-Amino Acid Abbreviations
| Codon | Full Name | Abbreviation (3 Letter) |
|---|---|---|
| CAG | Glutamine | Gln |
| CGT | Arginine | Arg |
| CGC | Arginine | Arg |

How do you memorize the abbreviations of amino acids?
Three acronym mnemonics for remembering the amino acids
- Non-polar side chains: “Grandma Always Visits London In May For Winston’s Party” (G, A, V, L, I, M, F, W, P)
- Polar side chains: “Santa’s Team Crafts New Quilts Yearly” (S, T, C, N, Q, Y)
What are the 64 codons?
The three-letter nature of codons means that the four nucleotides found in mRNA — A, U, G, and C — can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.
What are the 8 essential amino acids?
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
What amino acid is UAA?
| Amino Acid | Coding DNA Strand Base Triplets Not Transcribed | Transfer RNA Anticodons Complementary To M-RNA Codons |
|---|---|---|
| isoleucine | ATT, ATC, ATA | UAA, UAG, UAU |
| leucine | TTA, TTG, CTT, CTC CTA, CTG | AAU, AAC, GAA, GAG GAU, GAC |
| lysine | AAA, AAG | UUU, UUC |
| methionine (start) | ATG | UAC |
What does Aug code for?
AUG, as the start codon, is in green and codes for methionine. The three stop codons are UAA, UAG, and UGA.
What does Ugu code for?
Cysteine

What does UAG code for?
There are 3 STOP codons in the genetic code – UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation. These codons are also known as nonsense codons or termination codons as they do not code for an amino acid.
What are the amino acid abbreviations?
Amino Acid Codes
| Abbreviation | 1 letter abbreviation | Amino acid name |
|---|---|---|
| Asn | N | Asparagine |
| Asp | D | Aspartic acid |
| Cys | C | Cysteine |
| Gln | Q | Glutamine |
What is the 22nd amino acid?
Selenocysteine (Sec) and pyrrolysine (Pyl) are rare amino acids that are cotranslationally inserted into proteins and known as the 21st and 22nd amino acids in the genetic code.

How do you remember the names of the 10 essential amino acids?
You can remember the names of the 10 essential amino acids by using the mnemonic PVT TIM HALL. The PVT stands for Phenylalanine with its big side chain; the valiant Valine; and the third essential amino acid is Threonine.
What is the correct order of the amino acids in glutamine?
Asx B Cysteine Cys C Glutamate Glu E Glutamine Gln Q Glutamate or Glutamine Glx Z Glycine Gly G Histidine His H Isoleucine
How many base pairs are required for codons to encode 20 amino acids?
Codons are nucleotide triplets that encode for amino acids. Thus, in order for the 4 nucleotides to account for all 20 amino acids, a minimum of 3 base pairs are required. Can aminoacyl tRNA-synthetase structure be modified such that the triplet codon correspond to different amino acid than the ones on DNA codon table?
