亚硝基胍 meaning in English
nitrosoguanidine
Examples
- Nitrosoguanidine crystallizes when the solution is cooled to 0℃ .
当萃取液冷却至0时，亚硝基胍结晶析出。 - The effects of various mutagenic agents on the productivity of avermectin by slreplomyces avermilitis were evaluated in this work . three different mutagenic breeding methods were developed , such as ntg , uv , ion implatation
在育种研究中应用了离子注入、亚硝基胍和紫外线诱变方法，并对这几种诱变方法进行了比较，发现离子注入的诱变效果最好。 - At last , three strains of high activity was induced mutagenesis by ntg , after the routine screening procedures , activity of n28 and n118 was higher 47 . 5 and 40 . 9 percent than that of a . niger an01001 , and higher 29 . 5 and 23 . 7 percent than that of a199
最后，用亚硝基胍对产酶较高的3个菌株诱变，经复筛后， n28和n118的酶活比黑曲霉an01001高出47 . 5和40 . 9 ，比a199高出29 . 5和23 . 7 ， n28和n118经过5次连续传代后，产酶能力基本稳定。 - Monofunctional alkylating agent n - methyl - n ' - nitro - n - nitrosoguanidine ( mnng ) is a widely spread environmental mutagen and carcinogen that targets dna and proteins to generate adducts . among the adducts , o6 - alkyl guanine is the predominant mutagenic lesion because of its mispairing properties , which can eventually lead to chromosomal aberrations , point mutations , and cell death . this lesion also appears to be involved in tumor initiation , particularly in gastric carcinogenesis
单功能烷化剂n -甲基- n -硝基- n -亚硝基胍( mnng )是一种在环境中广泛存在的化学诱变剂和致癌剂，它能和dna及蛋白质等生物大分子形成加合物( adduct ) ，其引起的与突变有关的主要dna损伤类型是o ~ 6 -甲基鸟嘌呤，这种损伤与肿瘤尤其是胃癌的发生密切相关。
