Here are the codons for the 20 common amino acids. The three stop codons are included in the Reverse Complement (Rev. Comp.) section. The motivation here is to show graphically what amino acids the reverse complements (as DNA) code for. This information also yields potential six-nucleotide restriction sites. Example: KasI (G'GCGCC) codes for Gly-Ala. | The asterisk denotes amino acids with four codons which have the same two starting nucleotides (which by definition use all the other nucleotides at position three). |
