In our experiment performed with AO, a known frameshift mutagen, which acts by virtue of its intercalative DNA-binding ability (Ferguson and Denny, 1991), the concentration-dependent inhibitory effect of 1s, 2s and 3s was observed.
These strains were TA 98 and TA 1537, which primarily respond to frameshift mutagens, and TA 100, TA 102 and TA 1535, which respond to base-pair substitution mutagens.
