The major histocompatibility complex ( MHC) of fish was used to study the genetic structure as a molecular genetic marker of four populations of red common carp. 应用鱼类主要组织相容性复合体(MHC)基因来探讨鱼类种群间遗传结构,寻找分子遗传标记。
On the ground of the information of RFLP marker we had, we synthesized the PCR primers, devised restriction endonucleases, and transferred RFLP with complex operation and high cost into CAPS marker, whose operation is simple and applicable with low cost. 根据已有的RFLP标记信息,合成PCR引物、设计限制性内切酶,就可把操作复杂、成本较高的RFLP标记转化为操作简单实用,成本适宜的CAPS标记。
The matrilineal genetic structure of Yaos from Guizhou was relatively complex and the 9 bp deletion was a characteristic genetic marker of the matrilineal genetic structure of Yaos from Guizhou. 母系遗传结构相对复杂,9bp缺失是贵州瑶族的母系遗传结构特征。
Methods Microspheres were prepared by complex coacervation. Model protein drugs ( BSA) and polymers ( gelatin and arabic gum) were covalently labelled with a fluorescent marker prior to microsphere preparation. 方法微球用复凝聚法制备,牛血清白蛋白(BSA)为模型蛋白药物和聚合物(明胶与阿拉伯胶)为成球材料,在制备微球前均共价标记了荧光物。
Haplotype plays a very important role in modern genetic epidemiology studies. Especially, in the study of mapping common complex disease genes, haplotype-based methods, such as linkage analysis and association analysis, are more powerful than single SNP marker methods. 单倍型在现代遗传流行病学研究中起着非常关键的作用,尤其是在进行复杂疾病基因定位研究时,基于单倍型的连锁分析或关联分析方法比基于单个SNP位点的分析方法有更大的功效。
Due to the amount of crop drought resistance traits belong to a complex quantitative traits, the genetic improvement of drought resistance molecular breeding which based on the molecular marker linkage maps and gene mapping, has become an efficient breeding method. 但由于作物抗旱性状属复杂的数量性状,基于基因定位基础上的分子育种就成为抗旱性遗传改良的一条高效育种方法。
