The Gene Ontology project provides a controlled vocabulary to describe gene and gene product attributes in any organism.
This logical structure of a functional classification has been constructed by the Gene Ontology Consortium (2000).

The gene ontology is divided into three categories :

• Molecular function : a function that an individual protein or RNA molecule does. This is a function from the biochemists' point of view.

• Biological process : a component of the activities of a living system, mediated by a protein or RNA, such as signal transduction or cyclic AMP synthesis. This is a function from the cell's point of view.

• Cellular component : the assignment of site of activity or partners such as nucleus or ribosome.
