Abstract
The polarity of nonsense mutations in the galE gene of Escherichia coli can be suppressed by rho mutations (O. Reyes et al., J. Bacteriol. 126:1108-1112, 1976). We show here that this polarity can also be suppressed by ultraviolet irradiation. The effect is analogous to that already observed for polar nonsense mutations in phi X174 and S13 and suggests that ultraviolet irradiation suppression of polarity may be a general phenomenon.
摘要
大肠杆菌galE基因中无义突变的极性可被rho突变所抑制（O. 雷耶斯等人，《细菌学杂志》126:1108 - 1112，1976年）。我们在此表明，这种极性也可被紫外线照射所抑制。该效应类似于在噬菌体X174和S13中已观察到的极性无义突变的效应，这表明紫外线照射对极性的抑制可能是一种普遍现象。
