We assessed the presence of HBV DNA in serum samples from 36 patients HBsAg-negative hepatitis B by spot hybridization test with cloned HBV DNA probe.

应用斑点杂交方法对36例HBsAg阴性的各种类型的乙型肝炎患者进行了血清HBV-DNA的检测，33例获得阳性结果。

The arithmetic of the subtraction is based on the serial arithmetic. It can entirely enumerate every pair of subtrahend on a bit, and it also calculates two possible loaning carry values on each bit. So the subtraction can be operated through automatic selection, and complete collateral subtraction and carry operation. The method of single division is same to it. With the stenography of shifengshou we can solve the complex division. We put the formula and the technique into the DNA model to get the result. The methods all make the step decrease and change the conventional arithmetic.

减法的DNA 算法理论主要是来源于串行思路中的算法，它是将每一位上的两个减数对的所有可能进行全列举，同时考虑每一位上的两种借位信息，使得运算进行自动选择，一步即可得到最终结果的算法；除法中一位数除多位数的算法还是从我们平时所进行的串行运算中得到启发而设计的算法；而除法的多位计算思路则来源于史丰收速算法，将算法中的口诀及技巧应用到DNA 链当中，使得传统中的代数运算能够并行的得到最终的结果，这三种算法的设计都使得计算步骤减少，从根本上改变了算法的运算机制。

They also scanned the DNA to search for copy number ariations, which are submicroscopic insertions and deletions of genetic material that scientists beliee may be linked to autism and other diseases.

他们扫描DNA寻找DNA拷贝数量的变化，即遗传物质亚显微的插入和删除，科学家认为这一现象可能与孤独症和其他疾病相关。

In the last chapter, we briefly discuss analysis of similarity in view of longest common subsequence problem of DNA sequences.

最后，作为DNA序列比较的一种参照，我们从最长公共子序列的角度考虑了DNA序列的相似性分析，并进行了简单的讨论。

Using RAPD fingerprinting, we detected changes in PMCs'genomic DNA in Lilium davidii during prophase Ⅰ. The electrophoresis results revealed a specific polymorphism at synizesis stage, but not at other stages or in somatic cells.

采用RAPD指纹技术对兰州百合减数分裂前期Ⅰ中DNA结构变化的研究表明，在凝线期的花粉母细胞中存在着特异的DNA电泳谱带，在其它时期及体细胞对照中均没有。

The paper reviewed the research advance of DNA molecular markers in mulberry molecular systematics and their application prospect.

本文对DNA分子标记的种类及研究进展进行了综述，并展望这DNA分子标记技术在桑树研究中的应用前景。

Clone the final PCR product and BamH I cut the original DNA templet , The DNA synthesis complete.

采用类似的方法，完成所有的PCR循环，就可以得到所需要合成的DNA长片段。

For most viruses,there is aneed for antimicrobials that target unique viral molecular properties.Acycloviris one such drug.It is activated into ahuman herpesvirusDNA polymerase inhibitor exclusively by HHV kinases and,thus,does not suppress other viruses.Here,we show that ACV suppresses HIV-1in HHV-coinfected human tissues,but not in HHV-free tissue or cell cultures.However,addition of HHV-6-infected cells renders these cultures sensitive to anti-HIV ACV activity.We hypothesized that such HIV suppression requires ACV phosphorylation by HHV kinases.Indeed,an ACV monophosphorylated prodrug bypasses the HHV requirement for HIV suppression.Furthermore,phosphorylated ACV directly inhibits HIV-1reverse transcriptase,terminating DNA chain elongation,and can trap RT at the termination site.These data suggest that ACV anti-HIV-1activity may contribute to the response of HIV/HHV-coinfected patients to ACV treatment and could guide strategies for the development of new HIV-1RT inhibitors.

对大多数病毒而言，都需要有针对其分子特性的靶向杀毒剂阿昔洛韦就是这样一种靶向药物在人疱疹病毒酶的特定作用下，阿昔洛韦被激活成为人疱疹病毒DNA聚合酶抑制剂，因此不能再抑制其它的病毒我们的研究发现阿昔洛韦在共感染人疱疹病毒的组织中可以抑制HIV-1，但在无人疱疹病毒感染的组织或细胞中无此作用然而，加入人疱疹病毒-6感染的细胞却使得其对抗HIV的阿昔洛韦变得敏感我们推测这种抑制作用依赖于人疱疹病毒酶导致的阿昔洛韦磷酸化实际上，单磷酸化的阿昔洛韦前体药物无需人疱疹病毒的参与即可抑制HIV此外，磷酸化的阿昔洛韦能直接抑制HIV-1逆转录酶，将其阻止在终止位点，从而终止DNA链的延长这些结果提示阿昔洛韦的抗HIV-1活性决定了艾滋病病毒/人疱疹病毒共感染的患者对阿昔洛韦的治疗反应，也有助于开发新的HIV-1逆转录酶抑制剂
