Chemical RNA Tags May Drive Sheep's 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 molecules may help explain why some sheep undergo a dramatic seasonal shift from black to white coats. The finding suggests epigenetic tags on RNA, rather than DNA changes alone, could regulate the pigment-switching process, offering new insight into how animals adapt their coloring and how gene expression is controlled.
Why now: New research linking RNA chemical tags to a visible, dramatic trait change in sheep has caught scientific and popular attention.
