reactivities of benzene metabolites ( phenol , catechol , hydroquinone , 1,4-benzoquinone , 1,2,4-benzenetriol ) and related polyphenols ( resorcinol , pyrogallol , phloroglucinol ) with dna were investigated by a dna sequencing technique using 32p 5'-end-labeled dna fragments obtained from human c-ha-ras-1 protooncogene , and the reaction mechanism was studied by uv-visible and electron-spin resonance spectroscopies .
