The phylogenetic trees revealed the GD3 strain was a intergrade virus strain evoluated from classical PRRV CH-1a strain to the PRRSV JXA1 and HUN4 mutant strains indicated by 97.1 %, and 97.2 % nucleotide homology with JXA1 and HuN4 strain, 94.9% nucleotide homology with CH-1a strain.

序列分析结果表明，GD3株在分子遗传演化上介于PRRSV变异毒株(HuN4 株、JXA1株)和CH-1a之间，与HuN4和JXA1之间的相似性为97.1 %和97.2 %；与CH-1a的核苷酸相似性为94.9 %。

It plays an important role in maintaining the intracellular balance of A and G nucleotides.

该酶所催化的反应对维持细胞内腺嘌呤和鸟嘌呤核苷酸的平衡发挥着重要作用。

These variations may have some effect on gene structures and gene expression, and then contribute to intraspecific phenotypic diversities.

在物理图提供的序列基础上，对于籼粳稻两个主要栽培稻亚种进行了比较基因组分析，在2.3Mb对应区段中发现了两个亚种在基因组成和顺序上存在的广泛的微共线性，两者之间的差异主要由插入/缺失和单核苷酸多态性造成，这些差异可能影响基因的结构和表达，从而对种间表型差异产生影响。

The isolated working heart model was set up, high-performance liquid chromatography were used to measure myocardial adenosine triphosphate,total adenine nucleotides, while left ventricular end-diastolic pressure,left ventricular developed pressure, and rate of change of left ventricular pressure were determined before and after preservation.

对照组用St Thomas停搏液停搏并保存大鼠心脏6小时；实验组在St Thomas液中加入前列腺素E1(5 μg/L)停搏并冷保存6小时，利用离体鼠心非循环式Langendorff灌流功能测定模型，测定左心室舒张期末压、左心室发展压和左心室压力变化率，并检测心肌细胞线粒体三磷酸腺苷、腺嘌呤核苷酸总量。

The results showed that among Asia countries: Indian, burma, China, Pakistan and Kirghiz Republic,Hepatitis E virus genome shifted within the range of 5% and amino acid residues shifted within 1% compared with Mexico isolate.

结果 证明亚洲国家包括印度、缅甸、中国、巴基斯坦、吉尔吉斯坦流行的戊型肝炎病毒在基因水平和氨基酸水平上均有变化，核苷酸变化幅度在5%以内。

In 1984, Kirkman and Gaetani (1984) reported tightly bound NADPH in BLC, which then was also detected in the X-ray structure of BLC (Fita and Rossmann, 1985a). In the course of various sequencing projects a broad spectrum of catalase sequences from organisms of all kingdoms appeared in the public databases in the last 17 years e.g.

Vainshtein等获得了在3.5A 低等真核细胞中的过氧化氢酶的第一个电子云图，同时Eventoff 也得到了在2.5A处，用X-ray详细分析附面层控制图，1984年Kirkman 和报道了 Gaetani BLC中的紧密结合的还原型烟酰胺腺嘌呤二核苷酸磷酸

The promoter is typically haloarchaeal, but the start site of transcription is only seven bases from the 5'end of the initiator AUG codon, making the halC8 transcript another example of a"leadless transcript"in the haloarchaea.

它的-29～-24位置上是一"TATA"box序列，为典型的嗜盐古菌启动子；它的转录起始位点距离"ATG"只有7个核苷酸，也是典型的嗜盐古菌的"leadless transcript"。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
