The Gene Ontology (GO) project was established to provide a common language to describe aspects of a gene product's biology. The use of a consistent vocabulary allows genes from different species to be compared based on their GO annotations. For each of three categories of biological information--molecular function, biological process, and cel [..]

A hierarchical organization of concepts (ontology) with three organizing principles: molecular function, the tasks done by individual gene products, an example of which is 'transcription factor&# [..]

Gene Ontology (GO) is a controlled vocabulary used to describe the biology of a gene product in any organism. There are 3 independent sets of vocabularies, or ontologies, that describe: the molecular [..]
