While the cytosolic translation machinery is well characterized, the mitochondrial translation system remains largely elusive. Using cryo-electron tomography, Pfeffer et al. describe the ordered organization of mitochondrial polysomes in which each ribosome is tethered to the inner membrane by two defined contacts on the large subunit in situ.
