Method Electron microscopy P.438 caption to figure 1A: "A thin-section electron micrograph showing the density of ribosomes in the cytoplasm of Saccharomyces cerevisiae (courtesy of B. Byers, University of Washington). As much as 30–40% of the cytoplasmic volume is occupied by ribosomes (scale bar=100 µm)."
Comments P.437 left column bottom paragraph: "Comparison of the size of the genome (1.4×10^7 bp) with the RNA in a ribosome (5469 nucleotides) shows that there are nearly 200,000 ribosomes per cell (Fig. 1a)."
