May act by preventing a repressor protein from repressing transcription.

可以通过防止阻遏蛋白对转录的阻遏而发挥作用。

The first part of this paper is to set up a novel mathematical model describing expression and regulation of trp operon, in which not only the effects of repression and attenuation on transcription are taken into consideration, but the interaction between repression gene and structural gene as well as the transportation of tryptophan across cell membrane are also considered.

论文第一部分主要在已有的色氨酸操纵子模型基础上，建立了一个新的用于描述色氨酸操纵子动态行为的数学模型，它不仅考虑了阻遏、弱化以及反馈抑制作用对转录的影响，而且考虑了表达阻遏蛋白的基因和表达关键酶的基因之间的相互作用和影响，以及色氨酸外排的影响。

It follows that the mechanism of anodal relief of block can not be supposed to be simply a restoration of previously lowered membrane potential.

上述各种传导阻遏的特点，是或者根本没有膜电位的降低与之相伴，或者膜电位的降低发生在传导阻遏之后。

The wild-type represser protein can incompletely suppress foreign gene expression which show leaky nature.

阻遏蛋白不能完全阻遏外源基因的表达，会产生本底水平泄漏。

From the results of our studies we deduced that sucrose itself in the pith tissue of corn stalk could rule as a represser in someway to suppress the pathogen producing enzyme or toxin which can destroy host cells, or it could destroyor inactivate the enzyme produced by the pathogen, or it was not suitable for toxin surviving in it.

同时，从研究结果我们推断蔗糖本身可能具有阻遏镰刀菌产生酶类或毒素作用，病菌在侵染抗病品种过程中可能因寄主组织中蔗糖含量高，而导致病菌产生的可破坏寄主细胞组织的酶类受到阻遏或活性受到钝化；或者蔗糖不利于致病菌毒素的存活。

GA promotes plant growth via 26S proteasome-dependent proteolysis of DELLA proteins repressors, one of the key component in GA signaling, and also depends on GA-mediated interaction between GA receptor and DELLA proteins. Finally, this paper discussed the cross-talking between GA and other hormones, and modulation of adaptation to environments.

本文综述了赤霉素生物合成的生物学途径及其调控研究； GA信号转导通道的研究进展，特别是DELLA蛋白阻遏植物生长发育的分子机理和GA解除阻遏作用的分子模型； GA受体研究的新进展；探讨GA与其它激素之间的相互作用，以及植物在应答环境过程中的作用。

二。非同位素的方法筛选单链阻遏蛋白的最佳DNA结合序列初探克隆和表达了带半眈氨酸尾的单链阻遏蛋白，利用己包彼了马来酚胺的活性板可以与自由琉基结合的特性，将蛋白固定在活性板表面。

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。
