查询词典 populations

Therefore, we selected the 5 genes, as well as SMTN gene related to human cardiovascular diseases, for chromosomal mapping, CDS cloning and analysis, spatio-temporal distribution, mutation riddling, and association analysis with production traits of 3 porcine populations. We expect to know the structure and function of these 6 genes primarily, and supply data for porcine marker assistant selection of improving meat production.

因此，本研究选择NADH呼吸链相关基因，以及与人类心血管疾病相关的SMTN基因，以猪的骨骼肌为研究对象，用人×仓鼠体细胞杂种克隆板进行6个基因的染色体定位、CDS克隆和序列分析、用半定量RT-PCR进行时空表达谱分析、进行突变位点的筛选、并利用3个猪群的产肉性状资料进行基因型与性状的关联分析，以期初步了解这些基因的结构和功能，并为改进猪产肉性能的标记辅助选择提供资料。

Dr. Sandrock said there is no vaccine that will protect against the virus, but he said that if populations are old enough to have experienced the 1968 strain, for instance, they may have a host-adapted MHC?I primed T-cell response with epitopes, is appropriate for viral clearance may confer some protection and result in a mild to moderate disease, where the host would just "feel crummy."

Sandrock医师表示，没有可以抵抗此病毒的疫苗，但他表示，如果一些年纪较大者、曾经历过1968年的病毒株，他们或许有抗原决定位的原发T细胞反应、宿主-后天主要组织相容性复体第一型，适合病毒清除以及赋予一些保护力，造成疾病较轻微或中等，宿主的感觉相当轻微。

Lake Qinghai is the biggest inland saline lake in China. The main fish in the lake is scaleless carp. Initial analysis of its D-Loop showed no intraspecific genetic differentiation among the populations in the lake and the rivers around.
