The frequency of spontaneous reversion in r-mutants of phage T4 is determined in order to study the influence of mutant RNA polymerase on the level of spontaneous mutations in phage T4. The rate of spontaneous mutagenesis in the phage is found to be increased in strains with mutant RNA polymerase.
测定噬菌体T4的r突变体中自发回复突变的频率,以研究突变型RNA聚合酶对噬菌体T4中自发突变水平的影响。发现噬菌体中自发诱变率在具有突变型RNA聚合酶的菌株中有所增加。
