他们在使烟草细胞接触锌指核酸酶之外，也添加了可增强抗除草剂特性的基因片段。
When they exposed tobacco cells to the zinc finger nucleases, they also added a version of that gene that enhances herbicide resistance.
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 fingers are usually attached to enzymes called nucleases, dubbed ZFNs, which cut both strands of DNA.
他还补充说锌指核酸酶可能对一些基因具有不可预知的作用。
He adds that the zinc finger nucleases could have unpredictable effects on several genes.
我们可以通过对锌指的设计来靶向单个（特定的）基因，与此同时，核酸酶的存在将破坏该基因。
The zinc-finger design allows us to target a single gene, while the nuclease disrupts the gene.
