two of eight mutants ( bmr ) isolated in saccharomyces cerevisiae on the basis of their increased resistance to lethal effects of antitumor bleomycins ( bm ) , and about two-thirds of 180 yeast mutants ( bms ) isolated on the basis of their increased sensitivities to cell-killing by phleomycins ( pm ) or bm were sensitive to one or more of the agents uv , x-rays or hydrogen peroxide , thus these mutants are likely to be altered in processes acting directly or indirectly on dna damage .
