the number of chromatid gaps per 100 cells also increased linearly with concentration from 3.5 in the control cultures up to 117 with 1,6-dnp ( 1.25 micrograms/ml ) and 98 with 1,8-dnp ( 2.5 micrograms/ml ) , indicating that the induction of chromatid gaps was a valid and sensitive measure of chromosome damage in this cell line .
