We should increase support for old revolutionary base areas, ethnic minority areas, border areas and poor areas through pairing assistance and other means. 采取对口支援等多种形式,加大对革命老区、民族地区、边疆地区、贫困地区扶持力度。
Without specific base pairing, the replication enzymes cannot specify a complementary strand, and gaps are left after the passing of a replication fork. 失去特定的碱基互补配对,复制酶系就不能合成模板链的互补链,而是在经过复制叉后留下一个裂口。
Base pairing The bonding relationship between purine and pyrimidine bases in the nucleotides of DNA and RNA. 碱基配对:在DNA和RNA的核苷酸中,嘌呤和嘧啶之间相匹配的关系。
Antisense oligonucleotides sequence-specifically hybridize to the target mRNA through Watson-Crick base pairing and, therefore, inhibit the expression of the gene and proliferation of the cells and stimulate the apoptosis of the cells to prevent the cancer. 反义寡核苷酸则是通过WatsonCrick碱基互补原则,与目的基因或mRNA杂交,从而阻止基因的表达,抑制细胞的增殖,促进细胞凋亡,达到防止癌症的目的。
Many extrinsic factors such as alkylating can bring lesions to DNA base pairs, the alkylating destroy the normal base pairing or interaction between bases and proteins by connecting to NA bases. 很多外在因素比如烷基化物能对生物体的DNA碱基配对造成一定损伤,烷基化剂通过与核酸碱基作用从而破坏碱基之间的正常配对或碱基与蛋白质之间的作用,造成碱基错配。
The algorithm produces all possible secondary structures in lexicographic order by maximizing base pairing. 该算法根据极大基配对的原则按字典顺序产生所有可能的二级结构。
MicroRNAs ( miRNAs) are a class of endogenous noncoding single-stranded RNA with about 22-23 nucleotides length. MicroRNA function as sequence-specific negative regulators in post-transcriptional gene silencing by base pairing with target mRNAs, which leads to mRNA cleavage or translational repression. microRNAs(miRNAs)是生物体内源长度约为20&23个核苷酸的非编码小RNA,通过与靶mRNA的互补配对而在转录后水平上对基因的表达进行负调控,导致mRNA的降解或翻译抑制。
Sequence Homology and Base Pairing between Cucumber Mosaic Virus Satellite RNA and Potato Spindle Tuber Viroid 黄瓜花叶病毒卫星RNA与马铃薯纺锤形块茎类病毒间序列同源性与碱基配对
Next we focus mainly on the decomposition grammar, the calcula-tion of partition function and Boltzmann sampling of canonical joint structures as well as base pairing probabilities over multiple sequence alignments. 接着我们主要致力于介绍正则联合结构的分解语法、配分函数的计算、玻尔兹曼取样以及多重序列比对上的碱基配对概率。
