How do the ribosomes of prokaryotic cells differ from the ribosomes of eukaryotic cells? Also tell what is similar about them?
Ribosomes in the cytoplasm of prokaryotic and eukaryotic cells slightly differ. However, prokaryotes have 70S ribosomes, each consisting of a (small) 30S and a (large) 50S subunit whereas ,eukaryotes have 80S ribosomes, each consisting of (small) 40S and a bound (large) 60S submit.
Both prokaryotic and eukaryotic ribosomes are composed of ribosomal RNA and ribosomal proteins. Their basic functioning is protein synthesis.
