in vitro uv-light-induced unscheduled dna synthesis ( uds ) and mitomycin c ( mmc ) -induced sister-chromatid exchanges ( sces ) were scored in lymphocytes ( uv-light and mmc being the 'challenging agents ' ) , yielding higher uds values and lower frequencies of induced sces than cells of non-adapted animals .
