锌指核酸酶是一种人工制做限制性内切酶，通过将锌指DNA结合区与限制性内切酶的DNA切割区融合获得。

Zinc finger nucleases (ZFNs) are artificial restriction enzymes made by fusing an engineered zinc finger DNA-binding domain to the DNA cleavage domain of a restriction enzyme.

Or you could ask the question, I have this restriction enzyme, at what regions on this plasmid will it cut?

你也可以这样问,我的这种限制性内切酶,会从质粒的哪个区域切开呢

Cutting involves enzymes called restriction endonucleases or restriction enzymes, which I've already mentioned and they have names.

切割用到的酶叫限制性核酸内切酶,或限制性内切酶,我已经提到过了,而且它们都有名字

In this case, this particular restriction enzyme cuts symmetrically like this, but not at the same point.

在我们这种情况下,这个限制性内切酶总是这样对称地切割,但两条链切割的位点不一样
