[[File:RibosomeDiagram.png|300px|right|thumb|A [[diagram]] of a '''ribosome''' [[Protein Synthesis|synthesising]] a [[protein]].]]
A [[ribosome]] is a complex [[molecule]] found inside [[Cell (Biology)|cells]] that is the site of [[Protein Synthesis|protein synthesis]].
===About Ribosomes===
: '''Ribosomes''' are made of [[RNA]] and [[protein]] and take instructions form the [[Cell Nucleus|nucleus]] to [[Protein Synthesis|synthesize proteins]].
: [[DNA]] in the [[Cell Nucleus|nucleus]] creates a length of [[RNA]] which leaves the [[Cell Nucleus|nucleus]] and attaches to a '''ribosome''' to [[Protein Synthesis|synthesise]] a [[protein]].
