- Molecular 'Clutch' Of Bacterium Is Detached By Protein
It has been long been known that bacteria swim by rotating their tail-like structure called the flagellum. The rotating motion of the flagellum is powered by a molecular engine located at the base of the flagellum. Just as engaging the clutch of a car conn ...
