转录终止 meaning in English
transcription termination
Examples
- A new method for intrinsic terminator prediction based on rnall , an rna local secondary structure prediction algorithm developed recently , and two u - tail score schemas are developed . by optimizing three parameters thermodynamic energy of rna hairpin structure , u - tail t weight , and u - tail hybridization energy , the method can recognize 92 . 25 of known terminators while rejecting 98 . 48 of predicted rna local secondary structures in coding regions negative control as false intrinsic terminators in e . coli . this method was applied to scan the genome of synechococcus sp
在过去二十年中,不少研究者已开始研究如何用计算方法来预测转录终止信号，如brendel和trifonov的双核苷酸分布矩阵法dinucleotide distribution matrix carafa等的统计方法transterm和rnamotif法等，这些方法都从不同方面考虑了rna二级结构和u -尾部的特征，而gester的预测模型则设定rna二级发夹结构是不依赖终止子的唯一因素。 - A complete round of transcription involves the recruitment of polymerase and general transcription factors to the promoter , rna chain synthesis initiation and polymerase escape form the promoter , rna chain elongation , and finally termination with relaease of polymerase and nascent transcript from the dna template
一个完整的转录循环包括ranp和通用转录因子被招募至启动子、 ran链合成的起始和ranp从启动子的脱逸、 rna链的延伸以及伴随ranp和新生rna链从dna模板释放的转录终止等过程。 - Considering alcaligenes faecalis pencillin g acylase ( afpga ) , which possesses the attractive characteristics for beta - lactam antibiotics conversions , the gene of pga was cloned into two expressing vector pkkfpga and psmlfpga . both the constructed plasmids psmlfpga and pkkfpga contained the pga gene , trc promoter and rrnb transcript terminator , differ in the replicon and antibotic marker , pkkfpga contained multicopy replicon ( cole 1 ) and ampicillin marker . while psmlfpga contained medium - copy replicon ( p15a ) and tetracycline marker
本文将粪产碱杆菌青霉素g酰化酶( afpga )基因构建表达载体pkkfpga和psmlfpga ， pkkfpga和psmlfpga均含trc启动子、青霉素g酰化酶基因、 rrnb转录终止子，其中pkkfpga含有氨卞青霉素抗性基因和cole1高拷贝复制子；而psmlfpga含有四环素抗性基因和p15a中拷贝复制子。
