核苷酸

In addition, these data indicate that the nucleotide sequences flanking the histamine biosynthetic genes in Staph.

此外，这些数据表明，核苷酸序列的侧翼，在金黄色葡萄球菌组胺生物合成的基因。

The two isolates were more closely related to CTN, with the homogeny of N gene and G gene as 89.1% and 85.6%-85.7% at the nucleotide level, but 97.6%-98.0% and 92.3% at the amino acid level respectively, than to other vaccine strains.

结论2株狂犬病毒是基因1型狂犬病毒，但无论是N基因还是G基因的核苷酸序列，以及推导出来的氨基酸序列与已知的1型狂犬病毒株及疫苗株均有一定的差异。

They shared the highest homology to "world-B" group isolates in Brassica pathotype (between 91.8% and 100%). Phylogenetic analysis based on the CP gene sequences of TuMV strains or isolates showed that these 6 TuMV isolates from Shandong belonged to "world-B" group.

所得6个分离物的CP基因的核苷酸序列同源性较高，在97.0%～99.4%之间，系统进化分析表明：它们与Brassica致病型分离物中的world-B组分离物的同源性最高（91.8%～100%），亲缘关系最近，从而从分子水平上将TuMV山东分离物划分为world-B组。

The special primers were designed and synthesized after the analysis to the nucleotide sequence homology of etrl recorded in GenBank.

通过对GenBank登录的已克隆的植物etr1基因序列进行核苷酸同源性分析，设计特异引物。

At home and abroad published the same 24 NDV sequence homology analysis showed that the nucleotide sequence homology of 80%-98.4%, and amino acid homology of 87.2%-98.2% in between.

与国内外发表的24株 NDV 相同序列的同源性分析表明，其核苷酸序列的同源性在80％－98.4％之间，氨基酸同源性在87.2％－98.2％之间。

The method introduced in this article is a promising way for estimating codon homozygosity of the absent amino acid, and it can be further used to evaluate the relative importance of nucleotide composition in determining codon usage.

本研究引入的新方法可以有效的预测基因中缺失氨基酸的密码子纯合性，同时该方法可以被用来判断基因中核苷酸组成对密码子使用影响的相对重要性。

A new strategy based on nucleotide composition for estimating codon homozygosity for the absent amino acids in calculating effective number of codons was also introduced.

此外，本文还引入并评价了一种基于核苷酸组成估算基因中缺失氨基酸密码子纯合性的方法。

Contributions deal with the molecular aspects of genetic variation and evolution, mutation, gene action and regulation, immunogenetics, somatic cell genetics, and nucleic acid function in heredity and development, and with the biochemical aspects of genetic defects.

该杂志还介绍基因变异和进化、突变、基因作用和调控、免疫学、体细胞遗传学中的分子生物学，以及遗传发育中的核苷酸功能。

The products it provides include capillary columns for proteomics fractionation, dialysis and equilibrium dialysis, dialysis membrane data, electrophoresis products, protein, peptide and multi-ring cpd., oligonucleotide, HPLC column applications and so on.

它提供的产品有用于蛋白组学分级的毛细管柱，透析和平衡透析，透析膜数据，电泳有关的产品，蛋白质、肽和多环化合物，寡核苷酸，高效液相色谱系列应用等等方面的各类产品。

It shows that the recent rapid decline on population and fragment of habitat leads to indigence in genetic diversity, and all three geographic units exhibits low levels of nucleotide diversity and haplotype diversity. The average genetic distance among all haplotypes was 1.32%, and the genetic variation within and between regions were 99.31% and 0.69% respectively.

结果发现，大鲵近期种群数量锐减和栖息地破碎化以及遗传漂变造成了大鲵遗传多样性的贫乏；三个地理单元均表现出较低的核苷酸多样性和单倍型多样性，各单倍型之间的平均遗传距离为1.32％，99.31％的遗传差异发生地理单元内，仅0.69％发生在单元间。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
