查询词典 DNA

The application of the genetic codes is another kind of permutable calculation . From DNA chain to mRNA chain , t RNA , ribosome , peptides , and to protein , each step has its own permutable calculation from chemical reactants to products . None step has an indispensable relationship

密码表应用体系中，从DNA分子到m RNA分子到t RNA，再到核糖体到肽链，没有一步使用了排列数计算方法，从而造成DNA分子信息传递时步步失真，最后变成了肽链具体位置上的氨基酸分子，这里的每一步信息传递都是对密码表的错误运用。

By using red blood cell broken-up solution,proteinase K and RNase,total DNA with high quality was extracted from the egg membranes in the incubated eggshells of two pheasant species,Reeves's Pheasant Syrmaticus reevesii and Ring-necked Pheasant Phasianus colchicus from Dongzhai Nature Reserve in Henan Province.

本实验以河南董寨自然保护区白冠长尾雉和环颈雉已孵化的卵壳为材料，利用红细胞破碎液、蛋白酶K及RNA酶等试剂，对卵壳膜内的总DNA进行了提取，建立了一种提取高质量DNA的新方法。

Therefore, both of the photooxidative DNA damage and the genetic polymorphism of the repair enzyme hOGG1 play some role in the development of pterygium.

因此，日照所引起DNA的光氧化性损伤及患者本身修复DNA的能力是否完备，都可能在眼翳的致病机转中扮演重要的角色。

We evaluated the photooxidative DNA damage, indicated by the specific content of 8-hydroxy-2'- deoxygaunosine (8-OHdG), in human pterygium. In addition, we analyzed the relationship between the genetic polymorphism of the DNA repair enzyme hOGG1 and the pterygium risk in a Chinese population.

首先，我们尝试以8-氢氧-2'-去氧鸟粪核糖苷( 8-hydroxy-2'- deoxyguanosine， 8-OHdG )为指标，找出眼翳组织中去氧核糖核酸( deoxyribonucleic acid， DNA )所受到的光氧化性损伤之证据。

And 〓 all bind to DNA in some strong fashion, as showed by the obvious disturbance of photophysical properties with introduction of DNA.

和〓都与DNA发生明显的结合作用。

Objective: To check the significance of pleural effusion examination of ADA and TB-DNA for diagnosis of tuberculous pleuritis.

目的：探讨胸水腺苷脱氨酶、TB-DNA检测，以及ADA、TB-DNA联合检测对结核性胸膜炎的诊断价值。

The genotypic polymorphism and polygenetic affinities of intergenus, interspecies and intraspecies among 21 strains from 6 yeast genus were studied with random amplified polymorphism DNA analysis.

采用随机扩增多态性DNA分子标记对6个属的21个酵母菌株的基因组DNA的多态性进行了研究，并采用聚类分析法评价它们之间的亲缘关系。

The study was to evaluate the genetic diversity of 69 tea cultivars of the preconcentrated core germplasms of Camellia Sinensis in China by the random amplified polymorphic DNA.Among 50 arbitrary primers, 32 primers could generate enough amplified bands for all the strains in this study.

以中国茶树初选核心种质中的69份种质为实验材料，采用改良的SDS法提取它们的基因组DNA，并运用优化的RAPD 分析体系对基因组DNA进行分子标记遗传差异研究。

Objective This study was designed to investigate the different status of provirus HIV DNA in non-progressor and progressor of HIV-1 infected persons.Methods HIV RNA, HIV DNA were detected with long-distance PCR,reverse-transcription PCR,Southern blot and molecular hybridization from plasma and peripheral blood mononuclear cells, using primers locating between long terminal repeats LTR(U5)-LTR and so on.

HIV是一种变异非常活跃的病毒，这种变异既有可能医疗增强病毒在宿主体内的适应性和生存，又有可能医疗使病毒复制受到阻碍，影响病毒在宿主体内的生存，为了更进一步掌握HIV变异规律，阐明HIV致病机理，我们用逆转录PCR、长片段PCR、Southern转印、分子杂交等对HIV感染无进展者和进展者HIV RNA、CD4细胞、HIV DNA及存在状态进行了研究。
