查询词典 structural gene

Simply assuming that under different conditions, gene expression levels have three regulation states, i.e., up-regulation, down-regulation and non-regulation states, we can probabilistically establish a model of gene regulation states to compute gene regulation probabilities under different conditions.

简单假设在两种不同的实验条件下被调控的基因表达水平表现为三种调控状态，即上调控状态、下调控状态和非显著调控状态，我们使用概率统计方法对基因调控状态进行建模。在该模型的基础上，我们应用三种参数概率估计方法对基因调控概率进行估计。

The further analysis indicated that the double gene transgenic petunia possessed stronger capacity to take up liquid formaldehyde than the control and the single gene, DAS or DAK, transgenic plants. This resuLt suggests that the expressed DAS and DAK might establish aHCHO-fixation pathway which functions in the double gene transgenic plants.

对液体甲醛吸收速率测定结果表明转DAS、DAK双基因的矮牵牛对甲醛的吸收速率明显快于对照植物和转单个基因DAS或DAK的植物，说明转基因表达产生的DAS、DAK可能构成一条甲醛固定途径，在转双基因植物中发挥作用。

The apxⅢA gene of Actinobacillus pleuropneumonie was amplified by PCR. The amplified DNA fragment 3 466bp was cloned into pMD18-T. After R.E. analysis and sequencing, the apxⅢA gene in pMD18-T was ligated into pBluescripⅡSK, the recombinant expression plasmid pET-28b/apxⅢA was constructed and analysed with R.E., the protein of apxⅢA gene expressed in E.coli BL21 was detected by Western blotting.

因胸膜肺炎放线杆菌的致病性主要是由毒素决定的，故参照猪胸膜肺炎放线杆血清2型菌株的序列(GenBankL1 2 1 4 5)设计了一对特异性引物，用PCR的方法扩增apxⅢA基因并得到了长 3 466bp的片段，然后将其克隆到pMD 1 8T中，经酶切鉴定和序列分析表明克隆是成功的；再将apxⅢA插入到原核表达载体pET 2 8b后，转化BL2 1 (DE3)，在IPTG诱导下获得高效表达，经Westernblotting检测证实表达产物有活性。

Comparing EMD method with traditional FFT method in the analytical process, Hilbert-Huang transformation is found to be superior in performance. Structural response of the warship subjected to underwater explosion is simulated numerically, and EMD method is applied to analyzing the structural impulse signals.

该方法不把信号分解成正弦或余弦函数，因此既能分析线性稳态信号又可用于非线性非平稳信号的分析，且避免了高频干扰结果的出现，被认为是近年来对以Fourier变换为基础的线性和稳态谱分析的一个重大突破。
