arbitrary primer meaning in Chinese
任意引物
Examples
- Among 70 arbitrary primers , 13 primers could get enough amplified bands for all strains
这13个引物对11株供试菌株均能扩增出清晰的谱带。 - The procedure of ddrt - pcr applicable for silver staining was optimized by adjusting the amount of several critical reagents , including total rna , anchor primer , arbitrary primer , cdna and dntp
通过调整ddrt - pcr中总rna 、锚定引物、随机引物、 cdna和dntp等关键试剂的用量，优化了适用于银染检测的ddrt - pcr方法。 - Among 54 arbitrary primers tested , only 9 primers could generate clear and reproducible fragments in 32 species belonging to 12 genera of the family gryllidae ; 9 primers in 15 species belonging to 7 genera of the family trigonidiidae ; 12 primers in 3 species belonging to the genus oecanthus of the family oecanthidae ; 12 primers in 4 species belonging to 3 genera of the family eneopteridae ; 13 primers in 1 species belonging to the genus homoeogryllus of the family phalangopsidae ; 13 primers in 1 species belonging to the genus sclerogryllus of the family sclerogryllidae ; and 13 primers in 1 species belonging to the genus eulandrevus of the family gryllomorphidae
本研究经用54种随机引物对57种蟋蟀的rapd扩增分析得出以下结论： 1 ）采用rapd技术，首次较系统地对中国蟋蟀总科7科26属共57种蟋蟀进行了系统学研究。在所试用的54种随机引物中筛选出可扩增出清晰可辨且稳定的rapd图谱的引物分别为：蟋蟀科9种、岭蟋科9种、树蟋科12种、结蟋科12种、蛛蟋科13种、铁蟋科13种、貌蟋科13种。 - Rapd ( random amplified polymorphic dna ) , which bases on the polymerase chain reaction ( pcr ) , is by far one of the most commonly molecular techniques to uncover dna sequence polymorphisms . the basic priciple of this technique is that an arbitrary primer ( usually lobp oligonudetide ) is used to amplify random segments of dna , and a small number of fragments will be amplified when the primer anneals on each strand over a length range . if sequence variation is present at the priming site , then a fragment may not be amplied , so the dna polymorphic can be detected
Rapd (随机扩增多态性dna )技术是二十世纪90年代发展起来的一项dna分子多态性检测技术，它建立于聚合酶链式反应( pcr )技术基础之上，利用随机合成的寡聚核苷酸序列为引物(一般为10个bp ) ，分别与dna的两条单链结合，在dna聚合酶的作用下，对基因组的特定区域进行pcr扩增，其电泳结果为不同大小和数目的dna谱带即rapd图谱，可反映基因组相应区域的dna多态性。 - Forty arbitrary primers were used in the analysis of the seven samples , within which five primers produced relatively stable diversity . in total 49 loci were detected by these five primers , including 25 diverse loci ( 51 % ) . pairwise genetic distances were calculated and accordingly cluster analysis was carried out and the genetic dendrogram of the seven samples were generated
在rapd分析中使用了40个随机引物对7个样本进行分析，经重复实验，筛选出了5个多态性较为稳定的引物，测到49个位点，其中25个( 51 )有多态性。
