Gene Function: The Comprehensive Classification System of the Gene Ontology

The Gene Ontology (GO) provides controlled vocabularies for gene functional annotation, and consists of unlinked hierarchies, including _____.A) Molecular FunctionB) Biological ProcessC) Cellular ComponentD) All of the above

D) All of the above

D) All of the above.

The Gene Ontology provides a standardized vocabulary for the functional annotation of genes and gene products across all species. It consists of three distinct ontologies: Molecular Function, Biological Process, and Cellular Component. These ontologies are hierarchical in nature and cover a wide range of biological phenomena, allowing researchers to annotate genes and gene products with specific terms that describe their functional roles. The Molecular Function ontology describes the elemental activities of a gene product at the molecular level, the Biological Process ontology describes the larger, coordinated activities carried out by multiple molecular activities, and the Cellular Component ontology describes the structures and locations within a cell where molecular activities occur. Together, these GO ontologies provide a comprehensive classification system for gene function annotation.
