dna hybridization meaning in English
dna杂化
dna杂交
Examples
- Pdms - glass microchip used for performing dna hybridization reaction . has been fabricated and studied
制作并研究了pdms芯片上的dna分子杂交反应。 - The 7 isolates were identified based on physiological and biochemical characterization , 16s rdna sequence , g + c mol % and dna - dna hybridization . isolate tl was identified as bacillus cereus . isolate gl , c4 and c5 were identified as bacillus megaterium
在上述试验的基础上，本文分别用生理生化性状、全细胞脂肪酸成分分析、 16srdna序列分析及dna - dna杂交实验对这7个含有nifh的菌株进行了鉴定。 - 1 . because the taxonomic division is rather complex and has been much disputed and revised , in this part , we will review the classification and phylogeny of families , subfamilies and tribes of anseriformes based on morphology , ethology , osteology , mitochondrial and nuclear dna restriction fragment length polymorphism , single - copy nuclear dna hybridization and the sequences of mitochondrial gene analysis referring to the different definition , classification and phylogenetic relationships of the families , subfamilies and tribes of anseriformes . the controversial questions and deficiency in the systematic studies of anseriformes were pointed out
具体包括以下几个部分： 1 、针对雁形目鸟类异常复杂的分类状况及分类上存在的争议，根据雁形目鸟类的形态学、行为学、骨骼学、角蛋白、线粒体与核dna酶切片段长度多态、单拷贝核dna - dna杂交及线粒体基因dna序列分析等方面的研究，对雁形目鸟类分类中科、亚科和族的划分及其相互间的系统发生关系进行综述，分析系统学研究中存在的不足，提出了雁形目鸟类分类中急需解决的问题。 - Other groups were identical phylogenetic groups . to determine the exact taxonomic position and phylogenetic position of the rhizobia isolated from the root nodules of pueraria spp , the dna g + cmol % test , dna - dna hybridization and 16s rdna full sequence must be studied
数值分类、 ypfcr分析、 16sn3napcr rflp分析对慢生葛藤根瘤菌的分群存在较大差异，说明葛藤根瘤菌内丰富的多样性和分类地位的复杂性，要确定其确切分类地位和系统发育关系，要通过g cmol含量测定、 dna - Genetic diversity and phylogeny of 55 slow - growing rhizobia isolated from peanut ( arachis hypogaea ) in china were determined by analysis of host - plant range , phynotype , 16s rrna rflp , 16s rrna sequence , 16s - 23s igs rflp , rapd , rep - pcr , dna - dna hybridization homology . at the same time , the competitive nodulation capacity of rhizobia , effect of host plants and soil ph on the rhizobia were determined for screening and improvement of high effective rhizobium inoculant
本研究采用宿主范围试验、表型性状测定、 16srrna - rflp 、 16srrna序列分析、 16s - 23srdnaigsrflp分析、 rapd分析、 rep - pcr分析和dna - dna同源性分析等技术系统研究了从我国不同地域分离的55株花生根瘤菌的遗传多样性及其在根瘤菌系统发育中的地位和相互关系。
