They are the site of translation in both prokaryotic and eukaryotic cells.
They are made up two units which are called large sub-unit and small sub-unit.
In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.
In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.
