No, they do not. Prokaryotic cells have no membrane-bound organelles such as rough endoplasmic reticulum. The 70s ribosomes found in prokaryotic cells are therefore free in the cytoplasm as opposed to attached to the rough endoplasmic reticulum.
Rough ER is usually found near the nucleus. Ribosomes on rough ER make many of the cell's proteins.
