Question: how are ribosomes different in prokaryotic and eukaryotic cells?
Answer: In prokaryotes, ribosomes include three separate rRNA molecules, whereas in eukaryotes ribosomes include four separate rRNA molecules. Ribosomes consist of a large subunit and a small subunit. ... In contrast, prokaryotic cells contain ribosomes reaching 70S, split into 30S and 50S subunits.
