Sentences with phrase «venom gene families»

Armed with the both the king cobra and Burmese python genome the team was able to show that, despite previous hypotheses that venom genes evolve «early» in the lineage leading to snakes, venom gene families do not duplicate early, in fact the study shows that the rapid and extensive expansion of functionally important venom toxin families is restricted to the venomous «advanced» snake lineage.

Not exact matches

Snake venoms are complex protein mixtures encoded by several gene families and these proteins function synergistically to cause rapid paralysis or death in prey.
