Mutation spectrum analysis oftransglutaminase gene in streptomyces fradiae after irradiation by n ion 氟氏链霉菌离子束注入突变谱的分析
The specific nontargeted mutation spectrum is different from that of targeted mutation , whereas the mutation occurs at damaged dna site . furthermore , we have demonstrated that low concentration mnng exposure induced comprehensive cellular responses 进一步地,我们还证明了低浓度mnng的作用下有广泛的细胞反应,尤其是在信号转导通路的激活和基因表达的改变的研究中取得了一些突破性的进展。
