核苷酸

A nucleotide consisting of one molecule each of a phosphoric acid, a sugar, and either a purine or a pyrimidine base .

单核苷酸磷酸、糖、嘌呤或嘧啶碱基中的一种，它组成的一个分子的苷酸

Thus, nucleotides in DNA or RNA are typically called 'bases'; consequently they are commonly referred to simply by their purine or pyrimidine original base components adenine, cytosine, guanine, thymine.

因此，核苷酸的DNA或RNA通常是所谓的'基地'；因此，他们通常被称为只要他们嘌呤或嘧啶在原有的基础上组成部分腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶。

Mitochondrial cytochrome b sequence were used to study the molecular evolution and phylogeny of Anser cygnoides(15 breed of Chinese goose), Anser anser(2 breed of domestic European goose) and Anser albifrons(the lesser white-fronted goose, Genbank accession number AF363031). Sequence analysis revealed that there were 29 variable sites and 4 haplotypes in 45 sequences, nucleotide diversity and haplotype diversity were 0.0068,0.45 respectively, insertion/deletion or frameshift mutation were not found in Cyt-b gene sequences(1143bp).

本实验测定了中国家鹅15个品种、欧洲鹅2个品种共44个个体的细胞色素b基因全序列，与Genbank库中自额雁细胞色素b基因序列合并在一起比对分析，17个家鹅品种和白额雁细胞色素b基因全序列均为1143bp，序列中没有缺失、插入或移码突变，共检测到29个变异位点、4种单倍型，核苷酸多样度和单倍型多样度分别为0.00648和0.45。

The functional allele at the W locus is Ipmyb2, which was newly found in Chinese populations, and it differs mainly in the intron regions from those of the reported allele Ipmyb1; in comparison to Ipmyb2, the newly found second allele ipmyb2 has eight substitutions in the exons, a 6-bp deletion, and a 19-bp deletion, causing ORF shifting, and exists mostly in white-flowered individuals.

以上结果表明：1花青素代谢途径上酶基因的位点均有一定程度的多态，其中尤以ANS为最高；调控基因ipmyb2的核苷酸缺失造成该基因停止功能，使其纯合子的个体开白色花。2授粉者所介导的花色表型选择确实在中国种群中发生，有可能进一步增加花色代谢途径上基因位点的遗传变异。

In this study the genetic structure of the rat-like hamster from three locations in Hebei province and the Chinese hamster, the striped field mouse, the Chinese White-bellied Rat from two locations in Shandong Province were evaluated by SNP analysis of the full sequences of mitochondrial DNA control region.

本研究通过克隆与测序线粒体控制区全序列，采用单核苷酸多态性技术对河北、北京地区大仓鼠，山东地区黑线仓鼠、黑线姬鼠与社鼠种群的遗传多态性进行了研究，探讨了不同地理大仓鼠种群，黑线仓鼠、黑线姬鼠与社鼠种群遗传结构分布的形成原因，并对其之间的序列变异水平进行分析。

SNP Westminster Home Affairs Spokesman, Pete Wishart MP, has expressed concern over reports that immigration and citizenship proposals in the Queen's Speech contain clauses which will give state officials the power, previously reserved for times of war, to demand proof of identity at any time.

单核苷酸多态性威斯敏斯特民政事务局发言人皮特维希特议员表示关注，有报告说，移民和公民提出的女王的讲话包含的条款，这将给国家官员的权力，以前保留的战争时期，需求的身份证明文件的任何时间。

When put into cells, the new microRNA behaed just like miR-29b, wandering far away from the cell's protein-making machinery and into the nucleus, where the cell's genetic material is kept.

将这六核苷酸切下并粘合在其他的microRNA分子上，研究者们发现新组装的microRNA的行踪与miR-29b一样诡异，不&理睬&细胞中蛋白合成的分子机器，径直进入细胞核这个细胞遗传物质存储的地方。
