It's a gene that allows you to deliver a drug that's not active but the gene causes that active - that inactive drug to be converted into an active form that kills the cell.
这一方法利用该基因激活,另一种已经导入细胞的非活性药物,来杀死肿瘤细胞
In a normal cell DNA that DNA in the normal cell - this DNA gets cut by the restriction enzyme, so the sickle gene ends up - so that hemoglobin gene ends up in two pieces.
