基因失活 meaning in Chinese
gene inactivation
Examples
- Two americans , mario capecchi and oliver smithies , will share the one and one - half million dollar prize with martin evans of britain
他们在研究过程中发现了如何从实验生物中使单一基因失活或敲击它的方法。 - This year ' s nobel prize in medicine will go to three researchers who found a way to learn about the duties of individual genes
今年诺贝尔医学奖将会授予在研究个体基因方面有所发现的三名研究人员.他们发现了如何使实验动物体内的个体中特定基因失活，或失去作用。 - Though the technique of nuclejc transformation in plants has been developed and used widely , some problems in genetic information have not been resolved . for example , because the nucleic genome is so big and complicated that the integration sites and copies of foreign gene can not be controlled accurately , the expression of transferred genes is inefficient as a result of gene silencing or position effect . in nucleic transformation , furthermore , the transfer of multigene is difficult , and only after the prokaryotic genes undergo modification are they expressed in high plants
植物的细胞核转化技术已发展成熟并得到广泛应用，但核基因组的遗传转化仍存在一系列至今尚未解决的问题：例如由于核基因组大，背景复杂，外源基因的整合位点和整合的拷贝数难以人为控制，造成郑州大学2003年博士学位论文杜氏盐藻( dunaliellasalina )叶绿体转化研究外源基因表达效率低，容易出现基因失活、基因沉默、位置效应等现象;同时转入多个基因时操作步骤过于复杂，所表达的原核基因必须经过修饰改造，环境安全难以保证等。
