a general computational procedure for the modelling of intercalated dna-ligand complexes has been developed , and is used here to model intercalated complexes of the ( + ) -anti and ( - ) -anti enantiomers of benzo [ a ] pyrene diol-epoxide ( bpde ) with cytosine-3',5'-guanosine double-stranded dna sequences ( dcpg ) .
