#Octopuses Rewrite Their RNA to Beat the Cold | Rescue our Ocean's & it's species from Man's Pollution! | Scoop.it

This octopus from the Arctic tweaks its RNA to make nervous system proteins that work better in the cold. The Antarctic octopus edits its RNA at nine sites that change the amino acid sequence of the potassium channel, the researchers report online today in Science. One of these sites, known as I321V, was particularly important for adapting to the cold: The change more than doubles the potassium channel's closing speed.
