查询词典 terminus

There are three copies of R fragment in the S mt-genome, and each copy contains two closely adjacent open reading frames: orf355 and orf77. Among these three copies two BamHI fragments were cloned, and the sequence analysis showed that cox1 and cox2 gene lies upstream of the R region in each fragment, respectively. However, they locate in different strands and head to head with R. In this study, we found that:(1) The expression of cox1 and cox2 is not affected by the transcription of R region;(2) The two copies of R region transcribe in large amount in the microspores, and produce transcripts of 1.6kb and 2.8kb, respectively, in the sterile microspores; However, the abundance of these two transcripts is reduced in the fertility restored microspores, realized through the mRNA decay, and this reduction occurs at the uninucleate microspore stage;(3) In the sterile microspores, the 5 terminus of the 1.6kb transcript contains a palindrome region that can fold into a stem-loop.

本研究发现：(1) cox1和cox2的转录没有受到R区转录的影响；(2)两个拷贝的R区在在不育花粉中高丰度表达，其转录本大小分别为1.6kb和2.8kb；而在育性恢复的花粉中，这两个转录本的丰度被大大降低，进一步分析表明这一结果是通过mRNA分子的降解途径来实现的，此降解过程发生在单核花粉期；(3)在不育花粉中，1.6kb转录本的5′末端具有一段可形成茎环结构的迴文对称序列，而在可育花粉中，其5′末端短缺了9个碱基；(4)在不育花粉和育性恢复的花粉中，R区转录本的加尾位点都集中位于一个3′茎环结构之后；(5)不管是在不育花粉还是育性恢复的花粉中，orf77区域内均在第52位和100位核苷酸处发生了不同频率的C向U的编辑，从而形成UGA终止密码；(6)不管是orf55-orf77的成熟转录本还是转录前体分子，都已被加上了Poly尾巴，表明已进入降解途径；在以上实验结果的基础上，本研究对S型CMS花粉育性的恢复机理进行了如下推测：在不育花粉和育性恢复的花粉中，orf77区域内均发生了终止编辑，即由RNA编辑产生了提前终止密码子。

You could go back perhaps, he hasarded, still thinking of the very unpleasant scene at Westland Row terminus when it was perfectly evident that the other two, Mulligan, that is, and that English tourist friend of his, who eventually euchred their third companion, were patently trying as if the whole bally station belonged to them to give Stephen the slip in the confusion, which they did.

你也许可以回家去。他委婉地说，心里却仍回顾着在韦斯特兰终点站的不愉快场面：另外两个家伙--即穆利根和他那英国旅伴，就好像那座讨厌的车站属于他们似的，显然试图趁乱把斯蒂芬甩掉，并终于让他们的第三个伙伴上了当。

The station was used primarily by the Illinois Central Railroad , as the terminus for its main line from Chicago, but, over time, it also served a number of other lines, including the Southern Pacific Railroad and the Yazoo and Mississippi Valley Railroad .

该站主要用于由伊利诺伊中央铁路公司，作为该总站，以供其主线从芝加哥，但是，随着时间的推移，它也提供了一些其他线路，包括南部太平洋铁路公司和密西西比河谷亚祖和铁路。

At the edge of city, the anchorless Liang Shan Bo knew from the unacquainted Old drunkard that, there would be a special wedding in the "world terminus", and he was curious about it.

After the click reaction of the SCL micelles and azide-terminus PNIPAM homopolymer, the novel PNIPAM-functionalized SCL micelles with pH-responsive cores and outer thermosensitive coronas were prepared, which was investigated act as excellent candidate of nanosized drug delivery vehicles. Finally, two types of novel shell cross-linked micelles in aqueous solution were prepared from these remarkable PMEO_2MA-b-P(DMA-co-QDMA)-b-PDEA triblock copolymers by cross-linking the inner P(DMA-co-QDMA) shell of micelles upon the addition of diazide tetra derivative in the presence of copper catalyst using click chemistry.

另外，还可以使用溴丙炔对ATRP聚合出的PMEO_2MA-b-PDMA-b-PDEA三嵌段的中间PDMA嵌段进行部分季胺化，这样可以利用两端叠氮化的四甘醇来交联由PMEO_2MA-b-PDMA-b-PDEA在不同条件下形成的两种分别以PMEO_2MA或PDEA为核的胶束，从而实现了从同一个聚合物直接在水溶液中得到两种内核不同敏感的壳交联胶束。

It had the structuraL arrangement of four conserved cysteine residues C~(56, C~(87), C~(98) and C~(118) with two disuLphide bonds towards the carboxyL terminusas found in Large known cystatins, however there is a cysteine residue C~(56 in the different Location from the others, which was removed to N-terminus.

但大黄鱼的四个半胱氨酸残基中只有3个是与其它物种的位置是一致，另有一个半胱氨酸残基C~(56向N-端偏移，这有可能影响其空间结构的形成。

It is inferred that HIRA proteins of gibel carp and coloreded crucian carp raise the possibility of a conserved function in the regulation histone gene expression because CagHIRA and CaHIRA also have 7 conserved WD repeats in their amino-terminus which found in a number of eukaryotic proteins that cover a wide variety of functions including adaptor/regulatory modules in signal transduction, pre-mRNA processing.

CagHIRA和CaHIRA的N端同样具有7个WD结构域，由于含有WD结构域的蛋白具有调节信号传递和mRNA前体加工的功能，可以推测银鲫和彩鲫HIRA蛋白可能同样具有调节组蛋白基因表达的作用。
