_D_e_s_c_r_i_p_t_i_o_n:

     This data set describes associations between GO molecular function
     (BP) terms and their direct parent 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 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:
