Two related killer strains of Saccharomyces cerevisiae were mutagenized and screened for nonkiller variants. About 20% of the mutants derived from one strain lacked all detectable double-straned ribonucleic acid (dsRNA). About 70% of the mutants from the other strain lacked one of the dsRNA species normally associated with the killer factor and had in its place another species of dsRNA with a lower molecular weight.
对两种相关的酿酒酵母杀伤菌株进行诱变,并筛选非杀伤变体。来自一个菌株的约20%的突变体缺乏所有可检测到的双链核糖核酸(dsRNA)。来自另一菌株的约70%的突变体缺乏一种通常与杀伤因子相关的dsRNA种类,取而代之的是另一种分子量较低的dsRNA种类。
