transposable elements

Plant transposable elements are classified into two major elements or elements or DNA transposons.

转座元件是基因组中可移动的DNA分子,在真核生物的基因和基因组进化中起着重要的作用.

Drosophila is one of the best experimental material. Its genome consists of transposable elements.

果蝇是大量系统研究的最好实验材料之一,其基因组的10%～12%是由转座因子组成.

Dispersed repetitive sequence is mainly transposable elements which are composed of transposon and retroposon.

散在重复序列主要是可转移因子，可转移因子分为转座子和返座子两种类型。

In particular they tracked the positions of transposable elements.

详细来说,他们追踪了转座子的位置.

They identified thousands of segments that had the hallmarks of dead genes. They found transposable elements by the millions.

他们识别出了带有“死基因”标志的数千个DNA片段，还发现了数以百万计的转座因子。

CHH methylation of small transposable elements is increased in embryos, suggesting that endosperm demethylation enhances transposon silencing.

胚中小的转座元件CHH甲基化作用发生了增强，表明了胚乳的去甲基化增强了转座元件的沉默。

Transposable elements, or insertion elements, are DNA sequences which can be inserted into many different sites in chromosomes.

转位因子或插入因子是能够插入到染色体不同位点的dna序列。
