Abstract
A class of suppressors effective on nonsense polarity mutations suppresses several independent mutations in a gene (capR) that controls ultraviolet-radiation sensitivity and capsular polysaccharide synthesis. Since these ochre suppressors function at the level of translation of messenger ribonucleic acid into protein, the results provide evidence that the product of the capR gene is a protein.
摘要
一类对无义极性突变有效的抑制子可抑制控制紫外线辐射敏感性和荚膜多糖合成的基因（capR）中的几个独立突变。由于这些赭石型抑制子在信使核糖核酸翻译成蛋白质的水平上起作用，因此这些结果提供了证据，证明capR基因的产物是一种蛋白质。
