Zinc fingers are usually attached to enzymes called nucleases, dubbed ZFNs, which cut both strands of DNA.

通常附着在核酸酶上的锌指，称作ZFNs，它负责切断dna的两条链。

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.

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。
