Intracellular machines called ribosomes use messenger-RNA sequences to synthesize proteins. Investigations using single-molecule imaging and cryo-electron microscopy techniques reveal structural and kinetic differences in how human ribosomes function compared with those of bacteria. These differences explain why ribosomes in cell-nucleus-bearing species are slower and more accurate than their bacterial counterparts.
