The format is an R environment mapping the GO BP terms to all direct parent terms, where a direct parent term is a more general GO term that immediately precedes the given GO term in the DAG. _D_e_t_a_i_l_s: Each GO BP term is mapped to a named vector of GO BP terms. The name associated with the parent term will be either _isa_, _hasa_ or _partof_, where _isa_ indicates that the child term is a more specific version of the parent, and _hasa_ and _partof_ indicate that the child term is a part of the parent. For example, a telomere is part of a chromosome. Biological process is defined as the broad biological goals, such as mitosis or purine metabolism, that are accomplished by ordered assemblies of molecular functions as defined by Gene Ontology Consortium. Mappings were based on data provided: Gene Ontology:.
