Prokaryotic ribosomes are smaller and consist of 30S and 50S subunits, while eukaryotic ribosomes are larger and consist of 40S and 60S subunits. Additionally, eukaryotic ribosomes are generally bound to the outer membrane of the nucleus and the endoplasmic reticulum, while prokaryotic ribosomes occur free in the cytoplasm
