Do prokaryotic cells have a cytoskeleton?

It used to be thought that prokaryotes do not have a cytoskeleton, but better imaging techniques since the 1990s have shown cytoskeletal elements in bacteria and archaea.


Bacterial cytoskeletal proteins include a type unique to bacteria, along with elements homologous to eukaryotic cytoskeletal proteins (tubulin, actin, and intermediate filaments).
