The result shows that when ColE7 is bound to its prefer sequence, the DNA main chain was distorted the most and the scissile phosphate was located closer to the endonuclease active site, thus leading to a more efficient cleavage.

分析ColE7与DNA的复合晶体结构后发现，当ColE7与其偏好的序做结合时，其DNA主链的构型有相当明显的变化，且scissile phosphate较靠近活性中心区，可能因此导致较高的活性。

Since genomic DNA of high quality is a crucial prerequisite for molecular ecology studies, we specially detected efficient protocols to isolate high-quality genomic DNA from ethanol-preserved Pseudaletia separata adults of several natural populations trapped by light traps in fields of different areas.

高质量的基因组DNA样品是分子生态学研究的先决条件。

Two DNA slices separated on denaturing gradient gel from Sonneratia alba soil sample were recovered and the recovered DNA were used to establish two clone libraries.

这种制备光纤DNA传感器阵列的方法可用于中、低密度的基因芯片的生产。

It is illustrated that the DNA condensates display appreciabledimensional variations at the vicinity of critical spermidine concentrations.

这个方法被证明是研究临界致凝浓度附近的DNA的行为的有效途径，对DNA有序凝聚这一领域研究的方法学的建立具有一定的意义。

The DNA was extracted from mature Spinacia oleracea L.separately by the method of CTAB, then used as template after mixed by gender to be amplified with the optimized RAPD reaction condition. A total of 160 primers (10 bp) and 40 pairs of primers were screened, 44 primers of which produced clear patterns.

菠菜为雌雄异株植物，用CTAB法提取其雌雄成株幼嫩叶片总DNA分别构建雌、雄株的DNA池，以之为模板，用已优化的RAPD体系扩增，在160条随机引物(10 bp)和40个引物对中筛选出44个扩增效果较好的单引物，再从中进行进一步筛选。

Spreng was much more simple and efficient than the conventional methods. And the extracted DNA was suitable for the polymorphic analysis based on PCR, such as ISSR-PCR.

通过琼脂糖凝胶电泳和OD260/OD280比值测定，所得基因组DNA纯度高，可作为ISSR等以PCR为基础的DNA多态性标记。
