简介:DNA聚合酶III是为DNA的复制负责的五eubacterialDNA聚合酶之一双。在DNA聚合酶III核心酶的十个子单元之中,高山哈子单元两个都为polymerizing催化反应DNA海滨。在这研究,我们提取了高山的genomic序列哈从159的子单元定序eubacterial染色体,并且执行了基于顺序的种系发生、结构的分析。我们发现所有eubacterial染色体有至少一座高山哈子单元,哪个形式homodimers或heterodimers。种系发生并且领域高山的结构的分析以及拷贝数字变化哈在每个细菌的子单元显示高山的分类哈子单元进四个基本的组:polC,dnaE1,dnaE2,和dnaE3。这个分类具有在染色体作文分析的本质。我们也巩固了命名惯例在基因注解避免进一步的混乱。

简介:北塔山北麓的乌拉斯台地区索尔巴斯陶风景区,即美丽的乌拉斯台河西岸,蜿蜒多姿的乌拉斯台山谷中静静地矗立着一座口岸——乌拉斯台口岸."乌拉斯台"系蒙古语,意为生长有白杨树的地方.穿过4公里的口岸孔道,就可以到达蒙古国科布多省布尔干县.新疆昌吉回族自治州与蒙古国开展经贸活动已有多年.早在清代,乌拉斯台就是从奇台至科布多的古商道驿站.如今,乌拉斯台口岸作为昌吉州唯一的对蒙古国开放的国家一类陆路双边季节性口岸,是昌吉州对外开放的重要黄金通道.
