The '''Ribosome''' is the cellular [[organelle]] that is the site of [[protein synthesis]], specifically the translation of [[messenger RNA]] into a [[polypeptide]] chain. Ribosomes are unique among organic molecules in that they are made of both [[protein]] and [[ribosomal RNA]], making them functionally similar to, but not exactly, proteins. Ribosomes are formed in the [[nucleolus]] and many become attached to the membrane of the [[rough endoplasmic reticulum]], thus giving it its "rough" appearance.
