If a cell has a gene that makes it resistant to Ampicillin, that means that that micro-organism can survive being exposed to this normally deadly chemical without dying.
如果细胞带有一种基因,能够让它对氨苄青霉素产生抗性,即使把它放在,有致死剂量化学物质的环境中,它也能存活下来
If you selected the cells right than the only ones that have that resistance to Ampicillin are the ones that successfully got your plasmid and are using this Ampicillin resistant gene.
如果你选对了细胞,那么对氨苄青霉素有抗性的就是,成功得到了质粒并表达了基因的细胞
