what is the similarity between prokaryotic and eukaryotic ribosomes?
Prokaryotic ribosomes are bacterial ribosomes that are small (70S) while eukaryotic ribosomes are large ribosomes (80S). Prokaryotic ribosomes occur free in the cytoplasm while most eukaryotic ribosomes are membrane-bound. Both types of ribosomes consist of two subunits called large and the small subunit.
