_D_e_s_c_r_i_p_t_i_o_n:

     This data set describes associations between GO molecular function
     (CC) terms and their direct parent CC terms, based on the directed
     acyclic graph (DAG) defined by the Gene Ontology Consortium. The
     format is an R object mapping the GO CC 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 CC term is mapped to a named vector of GO CC 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.

     Cellular component is defined as the subcellular structures,
     locations, and macromolecular complexes; examples include nucleus,
     telomere, and origin recognition complex as defined b y Gene
     Ontology Consortium.

     Mappings were based on data provided: Gene Ontology (
