利用长距离PCR从稻瘟病菌附着胞cDNA文库中克隆了mnh6和mtp1基因的cDNA序列，并从基因组DNA中克隆了mnh6和mtp1基因的全长DNA序列。

Also, some patients with chronic hepatitis B have widely fluctuating HBV DNA levels that may vary from undetectable to 2,000,000 IU/ml.117 Thus, serial monitoring of HBV DNA levels is more important than any single arbitrary cutoff value in prognostication and in determining the need for treatment.

而且，许多患有慢性乙型肝炎的患者，HBV DNA水平波动的幅度很大，可从测不出到10'7copies/ml之间变动。因此，为了预测病情和确定是否有治疗需要，对HBV DNA水平的连续检测比任何武断确定的单个临界值更为重要。

Methods Molecular hybridization was used with 32 p labelled hPV 16,18,c Ha ras 1,c myc DNA and DNA in cervical tissue showed by X ary film autography.

应用缺口翻译法32P—标记的hPV16，18，c－Ha－ras－1及c－myc－DNA与子宫颈组织中的DNA进行分子杂交，并通过X线胶片显示杂交结果。

The method uses bacteriolysis enzymatic k of enzymatic broken wall, albumen and sds divide albumen, extract mangrove actinomyces dna, earning dna can undertake 16srdnapcr enlarge is added directly detect, have identification to actinomyces.

方法利用溶菌酶破壁、蛋白酶k和sds除蛋白，提取红树林放线菌dna，所得dna可直接进行16srdnapcr扩增检测，对放线菌进行鉴定。

基于线粒体COⅠ基因的DNA条形码技术应用于小蠹科昆虫分子鉴定的可行性研究通过对采自不同地区、不同寄主的15个小蠹虫样本的线粒体COⅠ基因研究，对基于线粒体COⅠ基因的DNA条形码技术应用于小蠹科昆虫分子鉴定的可行性进行了探讨。

Four stable maize DNA introgression lines and 4 stable barnyard grass DNA introgression lines were constructed and then investigated.

通过花粉管通道法将稗草总体DNA和玉米总体DNA导入水稻受体R122中，获得的D1代变异频率分别高达1.487%和3.81%。

There were only 5 cases negative for SYT-SSX genomic by seminested PCR, which were positive for SYT-SSX mRNA by RT-PCR. Three cases of synovial sarcoma negative for SYT-SSX mRNA were also negative for SYT-SSX genomic DNA. One case of synovial sarcoma was positive for SYT-SSX1 genomic DNA by seminested PCR, which can not be distinguished for SYT-SSX fusion type by RT-PCR.

只有5例SYT-SSX mRNA呈阳性而半巢式PCR SYT-SSX DNA检测呈阴性。3例RT-PCR检测SYT-SSX mRNA呈阴性者半巢式PCR亦为阴性结果。1例RT-PCR方法无法确定融合基因类型的病例SYT-SSX DNA检测为SYT-SSX1型。

The DNA samples were compared to a DNA of Astrid von Medinger, a in the female line of Stéphanie de Beauharnais, who would have been Kaspar Hauser's mother if indeed he had been the hereditary prince of Baden.

把他的DNA样品跟阿斯特丽德·范·米丁格的DNA片段对照。米丁格是斯蒂芬妮皇后的母性线上的后代，假如卡斯帕·豪泽尔真的是巴登国的继位王子，那么斯蒂芬妮皇后就应该是他的母亲。
