Here we compared , in the same sequence context , the relative NER dual incision efficiencies elicited by two stereochemically distinct pairs of guanine ( N ( 2 ) - dG ) and adenine ( N ( 6 ) - dA ) DNA lesions , derived from enantiomeric genotoxic diol epoxides of the highly tumorigenic fjord region polycyclic aromatic hydrocarbon dibenzo [ a , l ] pyrene ( DB [ a , l ] P ) .
 Chemical: guanine; Chemical: adenine; Chemical: diol epoxides; Chemical: dibenzo [ a , l ] pyrene; Chemical: DB [ a , l ] P
