in order to establish a good quantitative relationship between the number of acetylaminofluorene adducts and the extent of inactivation of dna , single-stranded ( ss ) ox174 dna and ox174 rf dna were modified to various extents with 3h-labelled n-acetoxy-n-acetyl-2-aminofluorene ( n-aco-aaf ) and subsequently transfected to escherichia coli spheroplasts having different repair capabilities .
