     This data set describes associations between GO Biological Process
     (BP) terms and their ancestor BP terms, based on the directed
     acyclic graph (DAG) defined by the Gene Ontology Consortium. The
     format is an R environment mapping the GO BP terms to all ancestor
     terms, where an ancestor term is a more general GO term that
     precedes the given GO term in the DAG (in other words, the
     parents, and all their parents, etc.).

_D_e_t_a_i_l_s:

     Each GO BP term is mapped to a vector of ancestor GO BP terms.

     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 by:
