The repressor is essentially a negative control mechanism.

阻遏物基本上是一种负控制机制。

Cellular repressor of E1A-stimulated genes protein's effect on vascular endothelial cells' apoptosis is unknown now.

而E1A激活基因的细胞阻遏子蛋白在内皮细胞凋亡中的作用，目前尚未见报道。

Negative regulation involves the binding of a repressor to the operator to prevent transcription.

负向调节涉及与阻遏基因与操纵基因的结合，以阻止转录。

Positive and negative regulation In negative regulation of prokaryotic gene expression,bound repressor prevents transcription of the structural genes.

正调控和负调控在原核生物基因表达的负调控中，与阻遏物的结合能够阻止基因的转录。

Transcription of the operon controlled by the lac repressor protein encoded by the lacI gene.

操纵子的转录是由LacI基因编码的Lac阻遏物蛋调控的。

If an inducer molecule is present, it binds to repressor and changes its conformation so that it is unable to bind to the operator.

若存在着一个诱导物分子，它会与阻遏基因结合，并改变它的构造，使它不能与操纵基因结合。

However certain molecules called corepressors can bind to the repressor protein and change its conformation so that it can bind to the operator.

但是，某些称为共同抑制物的分子可以与阻遏蛋白质结合，并改变它的构造，使得它能与操纵基因结合。

Aggregation group protein EED is a known transcriptional repressor, is considered a new NIPP1 protein interaction.

聚合组蛋白EED是一种已知的转录阻遏物，被认为是一个新的NIPP1互作蛋白。

The lac repressor The lacI gene has its own promoter to which RNA polymerase binds and initias transcription.

Lac阻遏物 LacI基因有自身的启动子，能够和RNA聚合酶结合起始转录。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
