This paper considers the stability and local Hopf bifurcation for a lac operon regulatory networks model, combing the global Hopf bifurcation for general functional differential equations, we investigate the existence of global Hopf bifurcation. 讨论了一类乳糖正负调控网络模型的正平衡点的稳定性及局部Hopf分支,并利用一般泛函微分方程的全局Hopf分支定理,讨论了该系统全局Hopf分支的存在性。
Insertion of ampicillin resistance translocation unit TN 2 in lac operon of E. coli K12 α-氨基苄青霉素抗性转座子Tn2在E.ColiK12乳糖操纵子Z基因中的插入区域特异性
Gene Knockout and Knockin on the Escherichia coli lac Operon Loci Using pBR322-Red System pBR322-Red在大肠杆菌lac操纵子基因敲除和敲入中的应用
The network analysis was used to lac operon system. 利用网络分析法对乳糖操纵子系统进行分析。
So we assured that the sites of structure genes in the lac operon of Escherichia coli chromosome were suitable for expressing foreign genes. 结果初步确定了大肠杆菌染色体上的lac操纵子结构基因位点适合外源基因的敲入和表达。
