<P> Prokaryotes have 70 S ribosomes, each consisting of a small (30S) and a large (50S) subunit . Their small subunit has a 16S RNA subunit (consisting of 1540 nucleotides) bound to 21 proteins . The large subunit is composed of a 5S RNA subunit (120 nucleotides), a 23S RNA subunit (2900 nucleotides) and 31 proteins . </P> <Dl> <Dd> <Table> prokaryotic ribosomes (E. coli) <Tr> <Th> ribosome </Th> <Th> subunit </Th> <Th> rRNAs </Th> <Th> r - proteins </Th> </Tr> <Tr> <Td> 70S </Td> <Td> 50S </Td> <Td> 23S (2904 nt) </Td> <Td> 31 </Td> </Tr> <Tr> <Td> 5S (120 nt) </Td> </Tr> <Tr> <Td> 30S </Td> <Td> 16S (1542 nt) </Td> <Td> 21 </Td> </Tr> </Table> </Dd> </Dl> <Dd> <Table> prokaryotic ribosomes (E. coli) <Tr> <Th> ribosome </Th> <Th> subunit </Th> <Th> rRNAs </Th> <Th> r - proteins </Th> </Tr> <Tr> <Td> 70S </Td> <Td> 50S </Td> <Td> 23S (2904 nt) </Td> <Td> 31 </Td> </Tr> <Tr> <Td> 5S (120 nt) </Td> </Tr> <Tr> <Td> 30S </Td> <Td> 16S (1542 nt) </Td> <Td> 21 </Td> </Tr> </Table> </Dd> <Table> prokaryotic ribosomes (E. coli) <Tr> <Th> ribosome </Th> <Th> subunit </Th> <Th> rRNAs </Th> <Th> r - proteins </Th> </Tr> <Tr> <Td> 70S </Td> <Td> 50S </Td> <Td> 23S (2904 nt) </Td> <Td> 31 </Td> </Tr> <Tr> <Td> 5S (120 nt) </Td> </Tr> <Tr> <Td> 30S </Td> <Td> 16S (1542 nt) </Td> <Td> 21 </Td> </Tr> </Table>
