coli lac operon repressor with its operator DNA has been directly examined as a function of the length of operator-containing DNA. The apparent bimolecular association rate constants were calculated as ka= (kdKD), where the dissociation equilibrium constant, KD and the dissociation rate constant, ...
To answer the question "In E. coli, the lac operon gets switched on when," we will analyze the components and functioning of the lac operon step by step.1. Understanding the Lac Operon: The lac operon in E. coli is a classi
