查询词典 damnified

The mutagen mechanism is presumed single factor dominant.(4)There was 85 percent transvertion in mutagen spectra, and they were all G:C→T:A transvertion. The maximal possibility of mutagen mechanism is analyzed as followed:ion beam implant → breakage cell surface and enter the interior → stimulate plentiful radical born → radical oxidize and damnify DNA → G becomes 8—oxoG → 8—oxoG pairing A → result in G:C→T:A transvertion(5)Production of transition was presumed that ion beam implantion damnified DNA, stimulate activity of MMR interveniented by methyl reducing.

诱发突变谱中碱基颠换比例是0.85，且是全部G：C→T：A颠换，推测低能离子束诱变鼠伤寒沙门氏菌得分子机制可能为：离子注入→通过破坏细胞表面进入内部→刺激产生大量自由基→自由基氧化损伤DNA→G变成8氧—7，8—二氢鸟嘌呤(8—oxoG)→8—oxoG与A配对→导致G：C→T：A颠换。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
