WebApr 28, 2024 · A eukaryotic ribosome is usually 80S. Eukaryotic ribosomes are larger because they contain more proteins and more RNA. Prokaryotic ribosomes contain 3 RNA molecules, while eukaryotic ribosomes contain 4 RNA molecules. The differences are subtle, as the ribosomes of each operate in much the same way. Related Biology Terms WebSep 23, 2024 · Each prokaryotic ribosome, shown schematically, has three binding sites for tRNAs.
