1·New phages can develop by acquiring restriction enzymes from plasmids.

通过从质粒获得的限制性酶，新的噬菌体能够生长。

2·Large DNA molecules are first dissected with restriction enzymes to produce specific fragments.

首先用限制性内切酶将大的DNA分子切断，产生出特殊的片段。

3·Restriction enzymes occur in bacteria as part of a natural defense mechanism to guard against invading viruses.

作为抵抗病毒的自然防御机制的一部分，限制酶存在于细菌中。

4·Bacteria have defences against viruses in the form of chemicals called restriction enzymes, which chop up foreign DNA.

细菌有一种对病毒的防御机制：一种叫做限制性内切酶的化学物质可以切断外源dna。

5·The method USES fluorescence microscopy to image individual DNA molecules that have been divided into orderly fragments by so-called restriction enzymes.

该方法应用荧光显微术使单个DNA分子成像，这些单个的DNA分子已经被分成有序的片断，因而被称为限制性内切酶的识别序列。

6·RFLP patterns were analyzed from 59 cultivars of Brassica napus, including 46 Chinese and 9 European accessions, using 28 genomic probes of Brassica and 2 restriction enzymes.

以甘蓝型油菜的28个基因组探针和两种限制性内切酶对包括46个中国品种、9个欧洲品种在内的59个甘蓝型油菜品种(系)的RFLP标记进行了分析。

7·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。

8·If different molecules are cut with the same restriction enzymes, the ends produced at each one have the capacity to bind to each other, joining together the two different molecules.

如果不同的分子用相同的限制酶切割，从每个分子产生的末端都能互相结合，从而将两种不同的分子连接在一起。

9·The Red mediated recombination can be used to insert, delete or substitute DNA sequences at any desired position on a target molecule without the need for restriction enzymes or DNA ligases.

这种技术可在DNA靶标分子的任意位点进行基因敲除、敲入、点突变等操作，无需使用限制性内切酶和连接酶。

10·This is in contrast to the restriction of glyoxysomes and the glyoxylate bypass enzymes to fat-storing tissues.

这与乙醛酸循环体和乙醛酸支路的酶类只限于脂肪贮藏组织是矛盾的。
