RNA Chemical Tags May Drive Sheep's Seasonal Coat Color Change
Original: Chemical Tags on RNA May Steer a Sheep’s Dramatic Black-to-White Coat Change
Researchers report that chemical modifications on RNA, known as epigenetic tags, may control how some sheep dramatically shift from a black coat in youth to white in adulthood. The finding suggests gene regulation at the RNA level, rather than DNA changes alone, governs pigment-switching, offering new insight into epigenetics and animal coloration.
Why now: The study offers a striking, easily visualized example of epigenetic regulation, drawing attention from science and biology audiences.
