By using random amplified polymorphic DNA technique, this paper studied the effects of Cd stress on DNA polymorphism in root tip of Vicia faba seedling s.

采用随机扩增多态性DNA技术检测镉胁迫对蚕豆幼苗根尖DNA多态性的影响。

In the bacteriophage phi29, a virus-encoded RNA is required for the packaging of its genomic DNA. Six pRNAs form a hexamer through pRNA/pRNA interaction to drive the DNA translocation motor, and ATP as the energy resource.

在噬菌体phi29中，基因组DNA的包装需要由病毒基因组编码的pRNA参与，6个pRNA分子通过由pRNA分子间相互作用形成的六聚体来启动DNA转运马达，这个过程由ATP提供能量。

Genomic DNA in eukaryotic cell is organized into nucleosome array and further packaged into higher-order structures. Each nucleosome is composed of a stretch of approximately 147bp DNA wrapping around a histone octamer, and neighbored nucleosomes are connected by linker DNA with length varies from 20bp to 100 bp.

中文摘要真核生物的基因组DNA能够与组蛋白形成核小体结构，这些核小体结构在基因组上线形排列，并进一步折叠成更加紧密和复杂的高级结构。

Bacteria genomic DNA was extracted to do polymerase chain reaction to amplify specific DNA and then to assess coden sequence.

萃取细菌DNA后利用聚合酶连锁反应将细菌特定的DNA片段增幅，定序比对标准序列判定基因型。
