This octopus from the Arctic tweaks its RNA to make nervous system proteins that work better in the cold
An octopus dwelling in the frigid waters of the Antarctic doesn’t wear gloves on its tentacles, but it has found another way to endure the cold. A new study shows that this animal uses a trick called RNA editing to customize crucial nervous system proteins to work at low temperatures. The paper is the first to reveal that RNA editing, not just changes to a specific gene, can lead to adaptations.
