Since organizational data management uses the metadata channel for creating a bi-directional flow, when correctly managed, metadata can save both time and resources for organizations. This paperI will focus on providing theoretical aspects of the two concepts, together with a short brief over a proposed model of design for an organizational management tool.展开更多
DW-ACP-PCR(DNAWalking-Annealing control primer-PCR)是一种分离已知DNA序列的侧翼未知序列的新技术。该技术通过3个嵌套的特异引物分别和ACPC复性控制引物组合,进行3步连续的PCR反应,所有反应可以在1 d内完成。ACP的特殊结构能有效...DW-ACP-PCR(DNAWalking-Annealing control primer-PCR)是一种分离已知DNA序列的侧翼未知序列的新技术。该技术通过3个嵌套的特异引物分别和ACPC复性控制引物组合,进行3步连续的PCR反应,所有反应可以在1 d内完成。ACP的特殊结构能有效地控制非特异扩增。用DW-ACP-PCR技术扩增7个稻瘟菌T-DNA插入突变体的T-DNA插入位点的侧翼序列,均获得了特异目标片段。展开更多
