In the careful dance of a bacterial cell's life, particular movements, such as cell division or the development of particular cell structures, occur only after previous steps are completed. But scientists haven't been able to find a master choreographer—until now. In an aquatic bacterium, researchers report finding a gene whose product coordinates the formation of a propellerlike flagellum with several other critical events, including DNA replication.
