Comments In table it is written "per 70s ribosome" and per rRNA precursor give a value of 6000. Not clear what means exactly. Bacteria have 70S (intact) ribosomes, each consisting of a small (30S) and a large (50S) subunit. Their large subunit is composed of a 5S RNA subunit (consisting of 120 nucleotides), a 23S RNA subunit (2904 nucleotides) and 34 proteins. The 30S subunit has a 1542 nucleotide RNA subunit (16S) bound to 21 proteins. Total nts 4566. Table 1 in primary source gives 1542 residues for 16S subunit and 2904 for 23S subunit
