查询词典 lac

用于增强lac和ara操纵子基因的转录，产生的蛋白在分解代谢中起作用。

CRP/CAP Catabolite activator protein,CAP is an activator required for high level transcription of the lac operon.The active molecule is a CRP dimer that binds 3'5' cyclic AMP to form a CRP-cAMP complex.

CRP/CAP 分解代谢物激活蛋白CAP是Lac操纵子高水平转录的一个必须的激活因子，有活性的CRP二聚体与3ˊ5ˊ-环式AMP结合形成CRP-cAMP复合物。

Degradation of chlorophenol compounds:①The degradation time for DCP, TCP and PCP wer 4h by Lac, and degradation rate can reach about 50%; IE degradation 2h, the degradation rate has exceeded 50%.

在相同pH值条件下，IE和Lac对TCP的降解效率最高，其次是DCP，PCP的降解效果最差。

We sustain that the peak frequency can become a well classificatory criteria of BL Lac objects and conceive that there are some systemic difference between XBLs and RBLs, and the difference is not only the result of choice.

作者在相关领域作的一些研究工作，我们的工作进一步支持了峰频作为BL Lac天体的一个有效的分类标准的观点，进一步猜想BL Lac天体的两个子类XBL和RBL的物理性质可能存在本质差异，而不仅是选择效应的结果。

In this study, 219 patients with colon cancer were randomized to treatment with either LAC or OC.

此次研究中，219位结肠癌患者随机接受LAC或者OC治疗，两组患者采用的辅助治疗以及术后随访，都是相同的。

Patients receiving LAC also recovered faster than those treated with OC in terms of time before detection of peristalsis and oral intake.

接受LAC治疗的患者与接受OC治疗的患者相比，从检测到肠蠕动以及进食的时间来看，恢复的速度更快。

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。

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。

Over a period of years the term "shell lac" has become known as "shellac."

过了一段时间，"shell lac"就被人们缩减成"shellac"。

Methods The skeletal muscle stem cells were enzymatically isolated with collagen and dispase, and then purified by different adhesion time from 6 female SD rats. The purified cells were transinfected with adenovirus carrying lac-Z gene, and injected into the bladder neck of 6 autologous and 4 allogeneic rats. Tissues of blader neck and ureter were obtained in sacrified rats after 5 and 15 days, histological examination and X-gal staining were performed.

采用混合酶消化及反复差速贴壁法分离、纯化培养SD大鼠骨骼肌干细胞，然后用携带lac-Z基因的腺病毒载体转染肌干细胞，待转染成功后将携带lac-Z基因的骨骼肌干细胞注射于自体和同种异体的膀胱颈及后尿道周围，分别于注射后5、15d，处死大鼠取出膀胱颈及后尿道，行组织学检查及X-gal染色。
