查询词典 transposon

The piggyBac transposon has been used most widely as an effective gene-transfer vector,because of its mobility in the genomes of a wide range of insect species.

由于该转座子在多种昆虫的基因组上都具有高转座活性，因此piggyBac已经成为一种高效的转基因载体广泛用于昆虫的转基因研究和实践。

One particular transposon first appeared about a million years ago. And by seeing where these sequences now sit, scientists can get a sense of the size of the breeding population back then.

第一个转座子出现在大约一百万年前，通过研究这些序列现在的位置，科学家可以大致知道当时可以生育的人口数量。

However, some transposon classes were apparently targeted by only one of these RNA classes, which suggested that piRNAs or siRNAs preferentially control certain TEs.

然而，一些转座子明显的仅仅被一种RNA所锁定，这意味着pi RNA或si RNA优先调控特定的TEs。

Rice plant separately . This two-element transposon tagging system can b e used to ge t mutants from a

稻突变群体，利用群体中的突变株系为材料分离水稻基因及进行基因的功能研究。

We found that Rhodnius prolixus, a triatomine bug feeding on the blood of various tetrapods and vector of Chagas' disease in humans, carries in its genome four distinct transposon families that also invaded the genomes of a diverse, but overlapping, set of tetrapods.

具体来说，长红锥蝽（一种以四足动物血液为食、是人类锥虫病传播媒介的虫子）的基因组中有四个截然不同的转位子家族，它们入侵包括负鼠和松鼠猴在内的一系列不同四足动物的基因组。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
