欧美的一些研究人员已研制出可以把外在克隆基因导入哺乳动物细胞的新载体,这些载体保证所导入的基因在宿主细胞内表达。该成就使基因疗法的前景得到改观。许多遗传病是单基因缺陷所致,基因疗法则是用正常基因的拷贝取代缺陷基因。某
Some researchers in Europe and the United States have developed new vectors that can introduce exogenous cloned genes into mammalian cells and ensure that the introduced genes are expressed in host cells. This achievement has improved the prospects for gene therapy. Many genetic diseases are caused by single-gene defects, while gene therapy replaces defective genes with copies of normal genes. certain
