内切酶,即限制性核酸内切酶。亦称限制性核酸酶。它是一种能催化多核苷酸的链断裂的酶,只对脱氧核糖核酸内一定碱基序列中某一定位置发生作用,把这位置的链切开。通过内切酶可以把某一个遗传基因切下来,若再连在别的细胞的遗传基因上,便可使这细胞具有新的遗传特性。内切酶的发现和采用,使基因工程成为可能。

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
