The phylogenetic tree was constructed using maximum evolution approach in Mega. The negative selection sites were analyzed by using Datamonkey. There is an apparent 30 bp nucleotides deletion mutation in homonids FKN comparing to that of Old World Monkeys besides other point mutations. Homology of nucleotide sequence between human and chimpanzee, gorilla, orangutan, gibbon, macaque and leaf monkey is 99.2%、98.4%、98.1%、96.5%、95.9% and 93.8% respectively. Homology of amino acid sequence of them is 98.5%、98.0%、97.7%、94.7%、93.7% and 90.5% respectively.

序列分析发现人猿超科较旧大陆猴FKN基因除了有散在的点突变外，还有一明显的30bp的核苷酸缺失突变；人FKN基因序列与黑猩猩、大猩猩、红毛猩猩、长臂猿、猕猴和叶猴的同源性分别是99.2%、98.4%、98.1%、96.5%、95.9%和93.8%，由此推导的氨基酸序列同源性分别是98.5%、98.0%、97.7%、94.7%、93.7%和90.5%；FKN基因进化树表明人与黑猩猩关系更近，FKN基因进化和通常认为的物种进化一致；Datamonkey分析结果显示FKN存在3个负选择位点53Q、84D、239N。

Single nucleotide polymorphisms are the most common form of human genetic variation, with millions present in the human genome.

单核苷酸多态是人类最常见的一种遗传变异，在人类基因组中多达数百万个。

Objective: The aim of this study was to estimate the contribution of polymorphisms in the positionally cloned asthma candidate genes ADAM33, PHF11, DPP10, GPRA and PTGDR to the risk of asthma, total and specific immunoglobulin E level, lung function and wheezing in a large, nationally representative, population.

为了评价原位克隆哮喘候补基因ADAM33， PHF11， DPP10， GPRA 和 PTGDR的多态性与哮喘发病危险因素之间的联系，Blakey等人在全国范围内进行了一项大型调查，他们选择了英国白人家族中1958年出生的独生子作为研究人群(n = 7703)，询问其喘息症状，测其总IgE、特异性IgE、肺功能，同时对其某些基因型和单核苷酸多态性进行相关分析。

HCV can not bind the CD81 of African Green Monkey. Four amino acids(163, 186, 188, 196) locating in EC2 of CD8I are different between human and AGM.

目的 探讨CD81、LDL-R基因在中国人中是否存在与HCV感染有关的单核苷酸多态性。

It showed that PRRSV may exist in other tissues of swines. Cloning and sequence analysis of open reading frame 5 gene of semen and aborted fetus, showed that homology of nucleotide and amino acid got to 100%.

通过对精液和流产死胎毒株的ORF5基因进行克隆和序列分析，发现核苷酸和氨基酸同源性为100％，进一步证实PRRS可以通过感染PRRSV的精液进行垂直传播。

Each nucleotide subunit consists of three components: a phosphate group, a deoxyribose sugar ring, and a nucleobase.

每个核苷酸亚基包括三个组成部分：一个磷酸基团，一个脱氧核糖糖环，和

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
