AIM: To find out common transcription factor binding sites in the promoter regions of the encoding genes of the co-expressive proteins induced by N-methyl-N '-nitro-N-nitrosoguanidine ( MNNG). 目的:分析甲基硝基亚硝基胍(MNNG)诱导的共表达蛋白的编码基因启动子区的转录因子结合部位。
Alternatively using mutagenic methods by mutagen Nitrosoguanidine ( NG) and Ultra violet ( UV), S. 301 strain of salmonella bovismorbificans was sift out. 应用诱变剂亚硝基胍(NG)和紫外线(UV)交替诱变处理法,诱变牛病沙门氏菌S。
Human gastric epithelial cell damage induced by N methyl N nitro N nitrosoguanidine MNNG诱导人胃粘膜上皮细胞的损伤作用
The auxotrophs obtained by nitrosoguanidine treatment were used as the markers for nuclear genotype of the haploid parents, and at the same time the petite form with mitochondrial mutation in globorubermycin resistance was used as the marker for mitochondrial genotype of fusion parents. 使用由亚硝基胍诱变所得到的营养缺陷型作为单倍体融合亲株的核基因标记,同时也采用线粒体球红霉素抗性突变株的小菌落形式作为融合亲株的线粒体基因标记。
