| 1. | A large number of hydrocarbons such as benzopyrene are also mutagenic .
大量碳氢化合物如苯并芘也是诱变剂。 |
| 2. | The first chemical mutagens to be discovered were the mustard gases used in world war i .
最初发现的诱变剂是第一次世界大战所用的芥子气。 |
| 3. | Study on removing dietary mutagen by antimutagenic lactic acid bacteria
抗突变活性乳酸菌对膳食中诱变剂去除作用研究进展 |
| 4. | Similarly , the cellular response to the environmental mutagens is not always initiated by dna damage
同样地，环境诱变剂诱发的细胞应答反应也不只是单纯地由dna损伤所触发的。 |
| 5. | Environmental mutagens can also induce mutations at undamaged sites and result in the so - called nontargeted mutation
环境诱变剂引起的突变也可发生在非dna损伤部位，我们称之为非定标性突变( nontargetedmutagenesis ) 。 |
| 6. | However , environmental mutagens can also induce mutations at undamaged sites and result in the so - called nontargeted mutagenesis
但是环境诱变剂引起的突变也可发生在非dna损伤部位，它被称之为非定标性突变( nontargetedmutagenesis ) 。 |
| 7. | The paper mainly deals with the chromosome doubling method and mutagen types for medicinal plants and other factors affecting chromosome doubling
本文着重介绍了当前药用植物染色体加倍所采用的方法、诱变剂类型以及其它一些影响植物染色体加倍的因素。 |
| 8. | From 19 arabidopsis male sterile lines isolated from an ethyl methanesulphonate - induced ( ems - induced ) population , a total of four male sterile mutants were screened with each mutant controlled by a single recessive gene
首先对19个经化学诱变剂ems处理得到的雄性不育突变体进行背景纯化和遗传分析，从中筛选到四个单个隐性基因控制的雄性不育突变体( ec2 - 157 、 ec1 - 188 、 ec2 - 115和ec2 - 214 ) 。 |
| 9. | For instance , the dwarf character in the plants treated with the dose of 80 x1015 was stable in inheritance in consecutive three generations . thus it can be seen that low - energy ion implantation causes developmental state changes and phenotypic variations and some changes and variations can be inherited stably
以上结果充分显示低能离子能够引起生物体dna产生变异，从而导致表型的变异，是一种有效的诱变剂，表明离子柬生物技术是一种非常有效的物理诱变技术，在生产实际中具有广泛的应用价值。 |
| 10. | Studies of genes related to heart development in drosophila contribute to reveal the mechanisms of human heart development and the congenital heart diseases . to clone and identify new genes that control the heart development , by a way of chemical mutagen , ems , we have established 1 , 200 balanced - lethal lines on chromosome 2 and 3 . with the screening the 330 stocks with immunochemical method using heart - specific antibody , mab . no . 3 , we detected 60 lethal lines showing heart mutant phynotype
为了克隆和鉴定控制心脏发育的新基因，本研究利用化学诱变剂甲磺酸乙酯大规模地诱变果蝇，并且建立了1200个第二和第三染色体的平衡致死系，利用心脏组织特异抗体mab . no . 3对其中330个品系进行免疫化学方法筛选，观察到有60个致死系表现出心脏突变表型， 20个品系的心脏突变表型有待进一步证实。 |
