If your gene goes in, you've interrupted the gene for antibiotic resistance and those new organisms aren't going to be resistant to antibiotic anymore.
如果基因进入了质粒,原本对抗生素有抗性的基因就被打断了,那些新细菌就不再对抗生素有抗性
One way that you can look for that gene that you want is by making the cut in your plasmid inside of a gene that encodes for some property like resistance to an antibiotic.
一种找到成功重组质粒的方式,是在质粒控制某种特性的编码区域切割,例如,对抗生素的抗性
I'll tell you, in the south of France near where we live, when there was a lot of resistance in World War II against the Germans, there were some Protestant villages there that were noteworthy for their resistance.
例如在法国南部,当时我们住所的附近,有一些新教徒的村子,这些村民们在二战中奋力抗击德国的入侵,并因为他们的不屈抗争而闻名
You could imagine strategies where you have multiple resistance genes on a plasmid, resistance to Ampicillin, to Penicillin, to Erythromycin for example, and you design strategies for separating out which cells are carrying the plasmid that you're interested in.
若质粒上有多种抗性基因,你就有很多筛选方法,例如对氨苄青霉素,青霉素,红霉素的抗性,而且你可以设计方法分离出,含有你感兴趣质粒的细胞
