Codon Reference Table

DNA My Name uses the standard genetic code — the same codon table used in molecular biology textbooks worldwide. Each amino acid is encoded by one or more three-nucleotide codons (triplets of A, T, G, C).

Amino Acids and Their Codons

20 standard amino acids are used. When multiple codons encode the same amino acid, DNA My Name uses a deterministic PRNG to choose between them — this is what shuffle changes. The non-letter fallback codon (for spaces, numbers, punctuation) is AAA (Lysine).

Code	Amino Acid	Codons	# Options
A	Alanine	GCT, GCC, GCA, GCG	4
C	Cysteine	TGT, TGC	2
D	Aspartic Acid	GAT, GAC	2
E	Glutamic Acid	GAA, GAG	2
F	Phenylalanine	TTT, TTC	2
G	Glycine	GGT, GGC, GGA, GGG	4
H	Histidine	CAT, CAC	2
I	Isoleucine	ATT, ATC, ATA	3
K	Lysine	AAA, AAG	2
L	Leucine	TTA, TTG, CTT, CTC, CTA, CTG	6
M	Methionine	ATG	1
N	Asparagine	AAT, AAC	2
P	Proline	CCT, CCC, CCA, CCG	4
Q	Glutamine	CAA, CAG	2
R	Arginine	CGT, CGC, CGA, CGG, AGA, AGG	6
S	Serine	TCT, TCC, TCA, TCG, AGT, AGC	6
T	Threonine	ACT, ACC, ACA, ACG	4
V	Valine	GTT, GTC, GTA, GTG	4
W	Tryptophan	TGG	1
Y	Tyrosine	TAT, TAC	2

Letter Substitutions

Six letters of the English alphabet do not correspond to standard amino acid one-letter codes (B, J, O, U, X, Z). DNA My Name substitutes them with the nearest biochemically reasonable amino acid.

Letter	Substituted To	Amino Acid
B	D	Aspartic Acid
Z	E	Glutamic Acid
J	L	Leucine
U	C	Cysteine
O	K	Lysine
X	G	Glycine
