Scientists have known for decades that genes called transposons can jump around the genome in a cell. This jumping can be dangerous, especially when it arises in cells that produce eggs and sperm. Although nature developed a mechanism to quash this genetic scrambling, how it works has remained a mystery. Now scientists have identified a key protein that suppresses jumping genes in mouse sperm and found that the protein is vital to sperm formation.
