The Bacterial flagellum is a helical protein structure protruding from the bacterial cell in order for the cell to move about. It acts as a propeller[1].

There are many components that build up the full structure of the flagellum. E. coli uses a total of 20 genes in order to create the nessesary appendage. The flagellum is built up of a rotor, stator and then has a kink in its flagellar filament which is called a hook.
