Objective A prospective study was organized to determine the accuracy and costeffectiveness of the TB AccuProbe DNA hybridization test,the PCR bases LiPA assay,and a verifying automated DNA sequencing of the rpoβ gene,for the routine rapid and direct identification of the Mycobacterium tuberculosis complex and Non Tuberculosis Mycobacterium and rifampin susceptibility.

目的用 3种先进的技术-TBAccuProbeDNA杂交法、INNO LIPATMRIF TB探针试验和rpoβDNA基因序列测定的前瞻性研究，以鉴定结核分枝杆菌复合物和非结核分枝杆菌及其成本效益。

Eleven subcloned DNA fragments from the 5′- upstream region of lipA, lipC and lipF of Phanerochaete chrysosporium were assayed by using the gel mobility shift assay. The total proteins extracted from P.chrysosporium mycelia grown in Kirk medium and natural fir wood chip were used to identify the segments in these 11 DNA fragments which are controlled by some regulatory proteins.

为了探索纤毛虫休眠细胞中两套遗传系统的作用特征，对包囊游仆虫休眠细胞与营养细胞大核DNA和线粒体DNA进行了RAPD比较。

And each cell has approximately 8,000 copies of mitochondrial DNA.

目前考古学研究中常用的DNA遗传标记是线粒体DNA分析。

Mitochondria have a small amount of their own DNA, which is called as mitochondrial DNA.

线粒体在自己的被叫做线粒体的DNA中数量很少。

At the same time, it can enhance utilization rate of phosphorus for monogastric animals and solve environmental problems as well.Three linearized DNA fragments without selectable marker gene and vector backbone were constructed containing phyA gene with regulation sequences or T-DNA borders or the plasmid borders.

我们构建了仅含有启动子序列、植酸酶基因和终止子序列的线性基因转化元件及其两端分别带有T-DNA边界序列或一段载体序列的不同线性转化元件，不含选择性标记基因和载体骨架序列，采用花粉管通道法对选定的玉米品种进行转化，共计收获的可以检测的种子为20400粒。
