查询词典 DNA

Overall genome size, and by extension the amount of junk DNA, appears to have little relationship to organism complexity: the genome of the unicellular Amoeba dubia has been reported to contain more than 200 times the amount of DNA in humans. The pufferfish Takifugu rubripes genome is only about one tenth the size of the human genome, yet seems to have a comparable number of genes.

整个基因组的大小以及根据垃圾DNA量的范围，好象与生物体的关系不大：据说变形虫的单细胞基因组含有200倍以上人类DNA数量。pufferfish Takifugu rubripes基因只是人类基因的大约十分之一，然而好象有了一个可比较的基因数量。

The results showed that the optimum concentration of five important components i.e. Tag DNA polymerase, Mg2+, primer, template DNA and dNTPs in 25μL RAPD reaction system were 1.0u, 2.5mM, 20ng, 40ng and 0.2mM, respectively. The RAPD fingerprinting of five Japanese plum cultivars were established by using optimum reaction system with ten random primers.

结果表明：1、改良陈大明法是提取中国李叶片基因组DNA的适宜方法。2、以5′-GACCGCTTGT-3′为随机引物，建立了优化的中国李RAPD反应分析体系：25μL反应体系中，Taq酶、Mg~(2+)、引物、模板DNA和dNTPs 5种主要成分的适宜浓度或用量分别是：1.0u、2.5mmol·L~(-1)、20ng、40ng和0.2mmol·L~(-1)。

The ISSR fingerprinting of 18 Japanese plum cultivars and 12 plum species or variety were established by using optimum system with primer 5"-9T-3"and 5"-9C-3", respectively. The identification rate of plum cultivars and species or variety was 100%. The effects of five important components on reaction of SSR were studied with Prunus salicina cv. Meilili. The results showed that the optimum concentration of five important components i.e. Tag DNA polymerase, Mg +, single primer, template DNA and dNTPs in 25 μL reaction system of SSR were 1.5u, 2.0mM, 0.8 μ M, 30~40ng and 0.16~0.24mM, respectively. The dendrograms of these cultivars was contructed according the Jaccard coefficient of similarity.

利用该优化体系，以5′-_9T-3′为引物，构建了中国李18个品种的ISSR指纹图谱，该引物可将这些品种完全区别开来；以5′-_9C-3′为引物，构建了李属6类种质资源的ISSR指纹图谱，该引物区分率为100％。4、中国李品种适宜的SSR反应分析体系是：25μL SSR反应体系中，Taq DNA聚合酶、Mg~(2+)、每个引物、模板DNA和dNTPs等5种成分的适宜浓度分别是：1.5u、2.0mmol·L~(-1)、0.8μmol·L~(-1)、30～40ng和0.16～0.24mmol·L~(-1)。5、采用RAPD、ISSR和SSR等三种分子标记技术对中国李品种资源54份和2个欧洲李品种进行了遗传多样性分析，并以品种间的遗传相似系数构建了Jaccard聚类树状图。

The adducts disturb the structure of DNA and inhibit DNA replication.

加合物的形成扰乱了DNA模板的结构，抑制了DNA复制。

DNA could be damnified by the NOCs in tap water directly, and the DNA adducts of such NOCs were formed in vitro and in vitro test.

东湖自来水中的NOCs有直接损伤生物体内外DNA、形成DNA加合物的作用。

Single-stranded DNA adsorbs on negatiely charged citrate ions on the gold nanoparticles while double-stranded DNA does not.

单链DNA金属微粒区吸附着负电荷柠檬酸盐离子，而双链DNA并不是这样的。

An enzyme that catalyzes the formation of DNA and RNA from an existing strand of DNA or RNA.

一种催化DNA或RNA的酶，利用一段既成的DNA或RNA作为核酸的模子。

Wherever the DNA is short circuited, there are two conflicting languages that vie to construct a part of the biology in tandem, and the lack of harmony creates a gap in the flow of the DNA.

无论哪里的 DNA 短路，两种冲突的语言在串联中争着去构建生物体的一部份，而和谐的缺乏制造了 DNA 流程中的裂缝。

Therefore, the goal of this thesis is to develop a feasible DNA immobilizing method, using electropolymerization of appropriate pyrrole-DNA conjugates.

因此本论文的研究目的是探索一个可行的通过电化学聚吡咯固定DNA的方法，以便应用于新型基于聚吡咯的DNA芯片的制作。
