Ribosomes are packets of RNA and Protein. They are the site of protein synthesis which allows for the messenger RNA from the cell nucleus to be moved systematically along the ribosomes where transfer RNA adds individual amino acid molecules to the lengthening protein chain. Ribosomes are too small to be seen under a light microscope and appear as random dots as free ribosomes and spots in a line as bound ribosomes under an electron microscope.
