Abstract

The increase of spontaneous and induced frequencies in mature sperm by N-nitroso-N-ethylurea visible mutation in the stock mei-9(11) of Drosophila melanogaster blocking the excision reparation has been shown. It is suggested that the mutation mei-9(11) blocks the correct way of reparation that is shown in mutator effect of this mutation.

摘要

已经表明,在阻断切除修复的黑腹果蝇品系mei-9(11)中,N-亚硝基-N-乙基脲可见突变会使成熟精子中的自发频率和诱导频率增加。有人提出,突变mei-9(11)阻断了正确的修复途径,这在该突变的诱变效应中得到了体现。
