Figure 1From: Accelerated exchange of exon segments in Viperid three-finger toxin genes (Sistrurus catenatus edwardsii; Desert Massasauga)Deduced amino acid sequences of the three-finger toxins. The segments with 85–100% identity are shown in the same colors and less than 65% identity is shown in different colors. The intron-exon boundaries are marked with dotted arrows (exon-intron).Back to article page
