Growing the right number of vertebrae in the right places is an important job – and scientists have found the molecules that act like ‘theatre directors’ for vertebrae genes in mice: telling them how much or how little to express themselves.
The finding may give insight into how the body-shapes of different species of animals evolved, since the molecules under scrutiny are present in a wide range of animals – ranging from fish to snakes to humans.
An auto-correct system for genetic errors in plants is helping plant breeders grow robust hybrid crops more efficiently. It also offers new tools for modifying human and animal proteins without modifying their genomes.
