Preparation of quasi-interpenetrating network/functionalized gold nanoparticle composite matrix and its performance for DNA sequencingA new matrix additive,PDMA-functionalized gold nanoparticle, was prepared by "grafting-to" approach to avoid GNP aggregation at high concentration of salt in buffer solution,and then incorporated into quasi-IPN composed of LPA(3.3 MDa) and PDMA to form novel polymer/metal composite sieving matrix(quasi-IPN/GNP-PDMA) for DNA sequencing by CE.

准互穿聚合物网络/官能化的金纳米粒子复合介质的制备及其用于DNA测序性能的研究为了解决GNPs在高盐浓度下易附聚的问题，由&grafting-to&法制备了一种新型介质添加剂，即PDMA官能化的GNPs，并将其加入到由LPA(3.3 MDa)和PDMA所组成的quasi-IPN中得到了用于毛细管电泳DNA测序的聚合物/金属复合筛分介质(quasi-IPN/GNP-PDMA)。

Life is a mirror for the internal fabric of the DNA; disunity DNA has "biological agents of destruction" that leads to aging, disease and death in the dance of life.

生活是内在 DNA 织锦的一个镜子。不统一的 DNA 拥有破坏性的生物性介质，造成了生命之舞中的老化、疾病和死亡。

Taken together, compared with the susceptible strain, the resistance strai ns have no obvious changes in karyotype but have distinct difference in DNA level, which suggests that insecticide resistance is related to the changes hi gen omic DNA in diamondback moth.

从上面的结果看来，与敏感品系相比，三种抗性品系小菜蛾的核型没有发生明显的变化，但在DNA水平上存在明显的差异，说明小菜蛾的抗药性与基因组DNA的变化有关。

The fungal DNA was extracted from three natural soils with greater differences in physical anti chemical properties in North China by using the second method, and the 28S rDNA-PCR-DGGE profiles showed that the fungal DNA banes were comparatively rich, suggesting that this method could be used in fungal diversity research of North China soils.

利用后一种方法分别对3种理化性质差异较大的中国北方自然土壤样品真菌DNA进行提取并分析，表明所提取土壤基因组DNA真菌特异性PCR-DGGE图谱条带丰富，该方法可用于多种北方土壤真菌多样性研究。

The method of CTAB-DNA isolation was optimized and used to extract genomic DNA from the tender leaves of 11 species of Cymbidium.

采用改进的CTAB-DNA提取方法，从11种兰属植物的嫩叶中提取总DNA。

Aim To search for the structural insights into the effect of isonucleoside on DNA:DNA duplexes and their thermal stabilization.

目的 研究异核苷的掺入对DNA：DNA双链的结构特征以及杂交热稳定性的影响。

This is in sharp contrast, of course, to the behavior of DNA–DNA duplexes, whose stability decreases dramatically at low ionic strength because of the required counterion shielding of the phosphate backbone.

当然，此现象截然不同与DNA-DNA二聚体的特性。由于后者的稳定性需要磷酸骨架的屏蔽，在低离子强度时，其稳定性将急剧下降。
