_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 children CC terms, based on the
     directed acyclic graph (DAG) defined by the Gene Ontology
     Consortium. The format is an R environment mapping the GO CC terms
     to all direct children terms, where a direct child term is a more
     specific GO term that is immediately preceded by the given GO term
     in the DAG.

_D_e_t_a_i_l_s:

     Each GO CC term is mapped to a vector of children GO CC terms.

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

     Mappings were based on data provided:
