RNA interference represents a common biological phenomenon of double-stranded RNA mediated post-transcriptional gene silencing, which lies in altitude plants and animals. The mechanism of this process is described as that: the dsRNA in cells are cut into double-stranded small interfering RNA. By joining with an effector complex termed RISC (RNA-induced silencing complex), siRNA binds to the cellular RNA with homologous sequences, and contributes to the degradation of the corresponding mRNA, the inhibition of specific gene expression.

RNAi技术是双链RNA(double strand RNA，dsRNA)介导的序列特异性的转录后基因沉默，广泛存在于高等植物和动物中，其机制是细胞内的dsRNA被Dicer剪切成双链的小分子干涉RNA (small interfering RNA，siRNA)与RNA诱导的基因沉默复合物结合，降解与之互补的靶mRNA，特异性抑制靶基因表达。

The immiscibility for A gum of xanthan may be correlated with the strong intermolecular hydrogen bonds themselves such as double-strand chain forxanthan and aggregation for A gum.

单胞菌和黄原胶共混相容性差是由于它们各自的分子间氢键较强，本身易形成聚集体或双螺旋体。

In vitro SUMO modification of the BRCA1/BARD1 heterodimer greatly increases its ligase activity, identifying it as a SUMO-regulated ubiquitin ligase. Further, PIAS SUMO ligases are required for complete accumulation of double-stranded DNA damage-repair proteins subsequent to RNF8 accrual, and for proficient double-strand break repair.

为了研究磁场对DNA的合成速度和DNA双链断裂的影响，我们选择比较简单的均匀磁场，从理论上探讨了此种磁场对DNA合成速度和DNA断链的影响，得到其合成速度改变和双链断裂程度与磁场强度大小有关。

Tobacco mosaic virus, a member of alphavirus-like superfamily, the N-terminal truncated TMV helicase formed hexamer and exhibited double strand RNA unwinding activity. Accordingly, we also constructed the same N-terminal truncated BaMV helicase-like domain and analysis the capability to unwind double-strand RNA.

在同属於alphavirus-like superfamily的Tobacco mosaic virus之解螺旋蛋白的分析中，其N端的截断蛋白会形成六聚体，而且具有解旋活性，因此我们同样建构了许多类解螺旋酵素N端的截断蛋白，测试其蛋白质的聚集形式及解旋活性。

The DNA double-strand in the biological system is complementary, in which a single strand contains all the genetic information. To investigate the behavior of electron transferring in the DNA double-strand, we can proceed with that in the single-strand.

生物体系中的DNA双链是互补的，其中单链上包含了有关的全部遗传信息，考察DNA双链结构中的电子转移行为可从研究其单链上的电子传递入手。

For maintain the genome integrity and fidelity. DNA repair processes are classified into pathways responsible for repairing specific classes of DNA damage, although recent data indicated that some proteins function in multiple pathways. Base excision repair occurs through excision of a damaged region, followed by fill-in repair synthesis using the opposite strand as a template. Mismatch repair operates on base mismatched and small loop-outs that arising during replication by misincorporation or slippage on the template strand. Nucleotide excision repair removes photoproducts from u.v. radiaton and bulky adducts from a multiple of chemicals. DNA double-strand breaks may be rectified by either homologous recombination repair and nonhomologous end joining pathways where both strands of the DNA duplex are damaged.

DNA修补基因可藉由不同的机制对不同程度的DNA损害进行修复，虽然近来已有文献指出，一些DNA修复蛋白可能参与多种DNA修复机制，不过一般可分为下列四种DNA修复机制：碱基删除修复(Base Excision Repair； BER)，即对较小的DNA损伤，进行修复；核苷酸错误配对删除修复，即对复制时所产生的核苷酸配对错误或模板滑动造成的DNA损害进行修复；核苷酸删除修复(Nucleotide Excision Repair； NER)，即对因紫外线或有机化合物所造成的较大损伤进行修复；以及双股DNA断裂修复(Double-Strand Breaks； DSBs)，即对双股DNA断裂进行修复，此机制又可分为同源染色体的重组与末端接合两种主要路径，对受损的DNA进行修复。
