Comments "The mass of ribosomal RNA per cell (mrRNA) measured in the studies of E. coli, S. coelicolor, M. bovis, S. cerevisiae (two studies), and N. crassa (Table 3) allowed [investigators] to estimate the cellular requirement of ribosomes for protein synthesis in the organisms as functions of the growth conditions by calculating the number of ribosomes and the peptide elongation rate (PER)."
