Genome annotation utilizes ontologies to establish controlled vocabularies that standardize biological knowledge sharing across species through hierarchical, directed acyclic graph structures. The Gene Ontology (GO) specifically categorizes gene products via three orthogonal aspects: molecular function, cellular component, and biological process, governed by the true path rule within an Is-A or Part-Of relationship framework. This theoretical system relies on formal evidence codes ranging from direct experimental assays to computational inference to assign consistent terms while excluding pathological or non-normal conditions.
