(A) Electron micrograph of E. coli 50S ribosomal subunits. (B–C) High resolution X-ray crystal structures of 30S (B) and 50S (C) ribosomal subunits. (D) Model of ribosome structure. (E) Components of prokaryotic and eukaryotic ribosomes. Intact prokaryotic and eukaryotic ribosomes are designated 70S and 80S, respectively, on the basis of their sedimentation rates in ultracentrifugation. They consist of large and small subunits, which contain both ribosomal proteins and rRNAs. (A, from M. Boublik et al., 1990. The Ribosome, p. 115.
