22. Prokariyotic Ribosome
• Prokaryotes have 70S 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.

23. • Eukaryotes have 80S ribosomes, each
consisting of a small (40S) and large (60S)
subunit. Their 40S subunit has an 18SRNA
(1900 nucleotides) and 33 proteins.[12][13] The
large subunit is composed of a 5S RNA (120
nucleotides), 28S RNA(4700 nucleotides),
a 5.8S RNA (160 nucleotides) subunits and 46
proteins
