Well the way to find it is by using a process called electrophoresis and Southern blotting.

找到二者差异的方法称作电泳和,琼脂糖凝胶电泳印迹

Electrophoresis is described in the chapter here, I'll just describe it briefly.

电泳法的描述在这一章这里,我只是大致解释一下

It takes advantage of the specificity of the restriction enzymes, the fact that we know what the gene sequence that we're looking for, and using this technological process of electrophoresis to identify changes that we predict.

这个方法利用了限制酶特有的性质,我们知道我们在找什么样的基因序列,从而才能利用电泳这个技术流程,来识别出我们预计的情况

I'm sure some of you have dealt with electrophoresis gels in the past and it's really just a slab of something like Jell-O where you can put a sample at one end of the Jell-O, your sample of fragmented DNA.

我相信在座肯定有些已经接触过电泳凝胶,真的挺像一块板状果冻的,你可以把一段样本放在"果冻"的一端,你的DNA片段样本
