After weaning, they switch off the gene that allows them to digest milk.

断奶后他们会关闭消化奶类的基因。

We even found the program predicted the order in which genes would switch on.

我们甚至发现了一个能够预测基因开启顺序的程序。

Then it uses molecular scissors to snip through both strands, which switches off the faulty gene.

然后用分子剪刀将双链剪除，这样就可以阻止错误基因的表达。

But, another gene that lives close by can interfere with or even switch that gene off.

但是另一个附近的基因就能干扰，甚至关闭这个基因。
