您要查找的是不是：
- The lac operon is an inducible operon, whereas the trp operon is a repressible operon. 乳糖操纵元是可诱导的操纵元；色氨酸操纵元是可阻遏的操纵元。
- In negative inducible operons, a regulatory repressor protein is normally bound to the operator and it prevents the transcription of the genes on the operon. 在负向可阻遏操纵子中，操纵子的基因转录一般都会发生。阻遏蛋白质会由调控基因所产生，但它们却不能够与操纵基因结合。
- In positive inducible operons, activator proteins are normally unable to bind to the pertinent DNA. 在正向可阻遏操纵子中，活跃蛋白质一般都会与适切的DNA段结合。
- 7．The lac operon is an inducible operon, whereas the trp operon is a repressible operon. 乳糖操纵元是可诱导的操纵元；色氨酸操纵元是可阻遏的操纵元。
- inducible operon 诱导性操纵子
- This diauxie curve is typical of inducible enzymes. 这种双峰曲线是诱导酶的典型增长曲线。
- Objective To clone and express the Trp operon gene of E. 目的克隆并表达大肠杆菌色氨酸操纵子基因,提高其酶活性。
- When the second operon with OC mutation, it will continue to express. 当第二个操纵子带有OC突变时，它将持续表达。
- Until now,crop breeders have paid little attention to inducible resistance. 直到现在为止，作物培育者还很少注意诱导抗性。
- Until now, crop breeders have paid little attention to inducible resistance. 直到现在为止，作物培育者还很少注意诱导抗性。
- To study this kind of genes, the inducible systems are more desirable. 创伤弧菌为一嗜盐性弧菌，属于人类伺机性病原菌。
- In this paper,the Monod lactose operon modelis described as a computer program by BASIC language. 本文用BASIC语言设计Monod操纵子数学模型的电子计算机程序。
- Glucose blocks induction of the lac operon by utilizing a positive control mechanism. 葡萄糖通过正调控机制阻止乳糖操纵元的诱导。
- Using a modified random arbitrarily primed PCR approach, the operon encoding the Enterococcus faecal ... 用改进的随机随机引物PCR的方法，操纵子编码的肠球菌粪便 ...
- Conclusion:WTTK6 cell was more sensitive to the chromosome damage induc... 结论:TK6细胞对受试物诱导的染色体损伤更为敏感。
- Consequently, if glucose is present in the medium, it is redundant to induce the lac operon. 因此，如果培养基中存在葡萄糖，诱导乳糖操纵元的打开就是多余的。
- Operon is a unit of bacterial gene expression and regulation, including structural genes and cis-acting control elements in DNA recognized by regulator gene product(s). 控制某一代谢途径的相关基因,紧密连锁地排列在一起,受同一操纵子控制。
- A chromosomal segment of DNA that regulates the activity of the structural genes of an operon by interacting with a specific repressor. DNA中的染色体元素DNA中的染色体，它是通过与一特殊的约束因子相互作用而控制遗传子结构基因的行为
- The agr system contains divergent transcription units driven by promoters P2 and P3. The P2 operon encodes AgrA, AgrB, AgrC, AgrD. P2操纵子编码AgrA、AgrB、AgrC、AgrD;
- Results:160 OPERON primers were screened and a primer H07 was found to be useable to differentiate the three Echinacea species. 结果:共筛选随机引物160个,3种松果菊中,狭叶松果菊与淡紫松果菊的RAPD图谱极其相似,难以区分。
