dna扩增 meaning in English
dna amplification
Examples
- All male goat - rabbit interspecies clone embryos samples had bands representing sry - specific , while female goat - rabbit interspecies clone embryos and control samples had no band
所有雄性样品中均出现清晰可见的特异dna扩增带，而雌性样品和空白对照中无扩增片段出现。 - Many streptomyces species exhibit a very high degree of genetic instability which is usually manifested as genomic rearrangement such as large deletion , and high - level dna amplification of those sequences flanking the deletion
许多链霉菌表现出高度的遗传不稳定性，通常为大片段缺失或基因组重排，以及缺失区域两侧序列的高水平dna扩增。 - In this work , some species of palmae cultivated in the xiamen botanical garden had been selected to be analyzed their genetic diversity with rapd ( random amplified polymorphic dna ) technique . according to the result of genomic dna amplified with pcr ( polymerase chain reaction ) , genetic distance and similarity between different palm species were calculated on nei " s estimate of similarity and genetic distance . a primary but first time research at the phylogenetic relationships of some genera and species , the molecular classification and identification of some puzzling species of palmae was carried out through upgma ( unweighted pair group mean average ) cluster analysis of the genetic distance together with comparative study of the morphological structure characteristics
本文在初步调查分析了棕榈科植物在我国的自然分布、引种驯化情况以及该类植物在厦门地区栽培应用状况的基础上，首次采用rapd分子标记技术，对厦门万石植物园引种的一些棕榈科植物的遗传多样性进行了研究，根据pcr对基因组dna扩增的结果，用nei ' s相似性系数计算了不同植物间的遗传距离和遗传一致度，通过对遗传距离的upgma聚类分析，并结合形态分类的特点，对棕榈科植物的属、种间的系统分类关系和一些疑难种的分类鉴定进行了初步研究。
