The genetic code |
Synonyms:
The triplet codons in DNA or RNA which codes for an amino acid

The codons UAA, UAG and UGA are stop codons which codes for termination of the protein synthesis.
In yeast mitochondria the codons AUA og UAG codes for Met and Trp and not for Ile and STOP as they normally do
