核酸酶

The group of low migration nucleases were prepared by ammonium carbonate processing +acid denaturation + thermal denaturation + acetone extraction.

在提取过程中产生两组核酸酶，在SDS-PAGE-DNA功能胶中迁移率较慢的一组采用碳酸铵处理+酸变性+热变性+丙酮沉淀的提取方法来获得较好的层析样品。

First, we determined the chromosomal location of the S locus in Antirrhinum by fluorescence in situ hybridization of metaphase chromosomes of a self-incompatible line of S〓S〓 using an S〓 RNase gene and its corresponding 63kb BAC clone as probes, respectively.

玄参科植物金鱼草的自交不亲和性和茄科和蔷薇科类似，都属配子体自交不亲和植物，它们S位点都编码一类控制花柱自交不亲和性的核酸酶，称为S RNase。

This was circumvented using specially engineered 'zinc-finger' nucleases as molecular scissors to cut DNA inside cells at a specific sequence.

现在，用特殊设计的"锌手指"核酸酶作为分子剪刀来在细胞内的特定序列上切割DNA，便能绕开这个问题。

Our results showed that 1, 8-Naphthyl imide could improve the properties of natural oligonucleotide in resisting nuclease and binding the targeted sequence by covalently linkage at the end of oligonucleotide. Moreover, our results also showed that the antigene oligonucleotide could specifically cleave the targeted double DNA sequence by modification of naphthyl imide at the 3'end of oligonucleotide.

体外结果表明萘二酰亚胺对寡核苷酸的共价修饰可以提高天然寡核苷酸抗核酸酶降解能力，提高寡核苷酸与靶序列结合的稳定性以及使寡核苷酸具有选择性结合和切断靶DNA的功能。
