  • a Values in the upper right are levels of amino acid similarity, and those in the lower left are levels of nucleic acid similarity. Values are calculated from data obtained from the EMBL nucleotide sequence database by using the GAP program for the similarity of nucleic acids and by using the TREE program for the similarity of deduced amino acids.
