Bases: adenine (A), cytosine (C), guanine (G) and thymine (T) or uracil (U).
Amino acids: Alanine (Ala, A), Arginine (Arg, R), Asparagine (Asn, N), Aspartic acid (Asp, D), Cysteine (Cys, C), Glutamic acid (Glu, E), Glutamine (Gln, Q), Glycine (Gly, G), Histidine (His, H), Isoleucine (Ile, I), Leucine (Leu, L), Lysine (Lys, K), Methionine (Met, M), Phenylalanine (Phe, F), Proline (Pro, P), Serine (Ser, S), Threonine (Thr, T), Tryptophan (Trp, W), Tyrosine (Tyr, Y), Valine (Val, V) Code 14 differs from code 9 (the echinoderm and flatworm mitochondrial code) only by translating UAA to Tyr rather than STOP.
A study in 2000[1] has found no evidence that the codon UAA codes for Tyr in the flatworms but other opinions exist.
There are very few GenBank records that are translated with code 14 but a test translation shows that re-translating these records with code 9 can cause premature terminations.
