查询词典 DNA

DNA methylating inhibitor makes the transfer of the methyl group to adenine or cytosine impossible,thus the reaction of DNA methylation is inhibited,the genomic methylation level is decreased.

DNA甲基化抑制剂使甲基基团不能转移到腺嘌呤或胞嘧啶，导致DNA甲基化反应受阻，从而使基因组甲基化水平降低。

The specific inhibitor of DNA methylation that is available currently is 5-Aza-2'-deoxycytidine (5Aza-dc), which forms a covalent bond with the DNA methyltransferase, thus, limiting the number of free DMT molecules for methylating DNA and then decreasing its biology activity.

目前研究较多的甲基化抑制剂是胞苷类似物5-氮杂-2'-脱氧胞苷(5-Aza-2'-deoxycytidine， 5Aza-dc)。5Aza-dc的作用机制是与DNA甲基转移酶共价结合，降低酶的生物活性。

A prominence advantage of DNA vaccine as a new generation of vaccine is that it can induce abroad cell immuno-reaction and form long perdured immunity memory, especially the immune regulative DNA vaccine which was constructed by special antigen together with some cytokine genes has more effect and prospect in the anti- coccocidiosis practice.

作为第三代疫苗的DNA疫苗的一个显著优势是刺激机体产生广泛的细胞免疫反应和持久的免疫记忆，尤其应用特定的球虫保护性抗原联合一些细胞因子，构建调节型DNA疫苗，在球虫病防治中具有诱人的应用前景。

DNA binding studies are very important for the development of new therapeutic reagents and DNA probes.

DNA结合的研究对新发展的治疗试剂寻找DNA探针的有非常重要的作用。

Recombinant proteins are created indirectly, by first recombining their DNA, and then expressing the protein from the recombinant DNA.

重组蛋白是用间接的方法得到的，首先将它们的DNA重组，然后从重组DNA表达出蛋白质。

DNA immunization with the Sj16 gene Plasmid DNA was prepared by QIAGEN plasmid mega kit and redissolved in NS at a final concentration of 1μg/μl.

Sj16基因DNA免疫研究用QIAGEN Plasmid mega大量质粒提试剂盒大量制备高纯度的pcDNA〓-Sj16、pcDNA〓和pUC19质粒DNA。

The genomic DNAs of the transgenic plants carrying Ac:: GUS were probed by Ac DNA in Southern blot analysis. Ac had excised from its original positions in T-DNA and reinserted at other genomic sites.

Ac因子作探针，与上述转基因植株的基因组DNA进行Southern杂交，结果表明，Ac从T-DNA解离后，重新整合到烟草基因组的其它位点。

In this thesis, based on a recent genome-scale dataset of DNA methylation in human brain tissues, we developed a classifier for predicting methylation status of CpG islands using a Support Vector Machine. Nucleotide sequence contents, transcription factor binding sties and Alu repeats are used as features for the classification. The method achieves accuracy of ~85% on the brain data.

本文的主要工作就是基于人脑测得的DNA甲基化数据，挖掘DNA序列特征，用支持向量机的方法实现了预测CpG岛甲基化的目标，得到了85%的预测正确率，同时还验证了所选的三类特征对于CpG岛甲基化的指导作用，它们分别是DNA序列组合、转录因子结合位点TFBS和短重复序列Alu。
