Lobanov ''et al.''<ref name='23rd'>PMID: 16713651</ref> searched "16 archaeal and 130 bacterial genomes for tRNAs with anticodons corresponding to the three stop signals". Their data suggest that "the occurrence of additional amino acids that are widely distributed and genetically encoded is unlikely." | Lobanov ''et al.''<ref name='23rd'>PMID: 16713651</ref> searched "16 archaeal and 130 bacterial genomes for tRNAs with anticodons corresponding to the three stop signals".
