Data in parenthesis are number of pups of which their genomic dna were analyzed 括弧内之数据为进行基因组dna分析之仔小鼠数。
The ams genomic dna has complex organization including 7 exons and 6 introns Ams基因组dna有一个复杂的结构,包含有7个外显子和6个内含子。
Dna ladder bands with a periodicity of about 200 bp were clearly seen in agarose gel electrophoresis pattern 琼脂糖凝胶电泳基因组dna可见到约以200bp为间隔的dna梯状( ladder )条带。
The followings were main results . 1 . the isolation of genomic dna was the first step of molecular markers research 1 、在前人研究基础上,建立了茶树基因组dna的sds -异丙醇提取法。
The dna quality was fresh > dry ones ; stored in liquid n2 > in - 20 ? . all of them were suitable for rapd and rflp analyses 基因组dna质量以新梢最好,干梢次之;液氮( - 196 )冷冻保存好于- 20保存。
