查询词典 DNA

The idea of computing aroses from the combination of DNA computing,the theory of tilings, and DNA nanotechnology.

它组合了DNA计算、Ting理论和DNA纳米技术，成为目前备受关注的模型之一。

To investigate the methods to effectively and simply assess the CAG repeat size of HD gene which was necessary for gene diagnosis of Huntington disease, the sequence including polymorphic CAG repeat of HD gene was amplified by PCR with TaKaRa LA Taq DNA polymerase and GC buffer. PCR products were analyzed on polyacrylamide gel to distinguish normal alleles from HD alleles. The DNA fragments of affected alleles were recovered from polyacrylamide gel as templets for secondary PCR. The secondary PCR products were cloned into T vector for sequencing analysis to determine CAG repeat size. A total of 20 normal individuals and 3 members from a HD pedigree were included in this study.

为了简单高效检测HD基因开放阅读框5'端n三核苷酸重复序列，建立快速准确的亨廷顿病(Huntington disease， HD)基因诊断方法，应用TaKaRa LA Taq DNA聚合酶配合GC buffer扩增HD基因包含n重复序列的目的片段，非变性聚丙烯酰胺凝胶电泳检测后回收n拷贝数异常增多的目的片段，再次PCR扩增后将产物连接至T载体，进行DNA测序确定CAG的拷贝数。

AFM was used for nanometer-level-structure analysis of DNA damage induced by a particle and these two kinds of heavy ions. Measurement of the fragment lengths was accomplished with the use of Scion Image analyzed software, which allows a curved fragment to bemeasured in a stepwise manner at nanometer level resolution, and the change laws of three forms of DNA, supercoil, open circular and linear form as the dose increased were obtained.

借助于AFM，对α粒子和两种重离子诱发的DNA损伤进行了纳米水平的结构分析，并结合Scion Image图像分析软件的分段测量方法，对辐照诱发的DNA碎片长度分布进行了纳米级分辨的测量。

Detecting each marker and cmparison the location of sequential tissuesection could determine the area loceation relationship of the markers, but it is difficulte to determine their correlation intra-cells exactly. No report of detecting virus genome and antigenes on a one section with triple staning techniques exists in the lit erature. in this report. by combining immunohistochemistry and in situ hybridization (with dioxigenin labelled HBV DNA probe), a triple staining technigce was established. With this technic, on one formalin-fixed and paraffin embeded section, HBV DNA, HBsAg and HBcAg were determinated one after the other.

各个细胞内病毒的复制和表达水平以及与肝细胞病变的关系，是乙型肝炎发病机理研究的一个重要方面：目前常用的在系列切片上对各标志物分别检测，比较观察的方法，一般只能大致了解各待检物在某一区域的定位关系，很难准确地了解它们在同一细胞内的关系：国内外尚未见有在同一张切片上三重标记染色检测病毒核酸及其多种抗原的报道：本文结合免疫组织化学ABC法及地高辛配基标记HBV DNA探针原位杂交，建立三重标记染色技术：在一张福尔马林固定石蜡包埋肝组织切片上先后检测，同时显示HBV DNA、HBcAg和HBsAg。

SUMMARY: Standard DNA alignment programs are inadequate to manage the data produced by new generation DNA sequencers.

标准的DNA比对程序不适合于管理由新一代DNA测序仪产生的数据。

DNA ploidy can more really reflect the content of DNA,which has long history in the relation study with tumor.

肿瘤细胞的重要生物特性是无限制增值，这个过程需要合成大量的核酸来完成，也使得细胞内的DNA含量发生变化，肿瘤细胞的DNA含量异常，是恶性肿瘤的重要标志。

The phloems of the annual branch deciduous tree had the traits to gather easily, and they were rich in DNA contents, this characteristic was suitable to extract DNA in the dormancy season.

落叶果树枝条具有取材容易、DNA含量丰富的特点而适合在休眠季节用于提取DNA，进而加速果树分子生物学研究进程。

Cloning of DNA is made possible by the ability of bacterial plasmids and phages to reproduce after additional sequences of DNA have been incorporated into their genomes.

将一段额外的DNA序列整合到细胞质粒和噬菌体的基因组上进行繁殖，使DNA克隆已成为可能。

Pedants may quibble that only the DNA of the new beast was actually manufactured in a laboratory; the researchers had to use the shell of an existing bug to get that DNA to do its stuff.

书呆子可能会诡辩只有新生物的DNA是实验室制造的；科学家不得不用现已存在的昆虫的壳取得DNA，然后才开始造物。

The primary role of PARP is to sense DNA damage, repair that DNA when it is damaged, and maintain stability in the body's cells.

PARP的主要作用是监测DNA是否受损，并对受损的DNA进行修复，维护机体细胞的稳定性。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
