According to the Sankhya philosophy, Prakriti is composed of three Gunas or forces, called Sattva (purity, light, harmony), Rajas (passion, activity, motion) and Tamas (inertia, darkness, inertness, inactivity). Guna means a cord. The Gunas bind the Self with a triple bond.
The lac operon is an inducible operon that utilizes lactose as an energy source and is activated when glucose is low and lactose is present. Learning Objectives Describe the components of the lac operon and their role in its function
The lac Operon-an inducible system. The first control system for enzyme production worked out at the molecular level described the control of enzymes that are produced in response to the presence of the sugar lactose in E. coli cell. The work was performed by Jacob and Monod for which they were awarded the Nobel Prize.n this system lactose acts as an effector molecule. Effector molecule-a molecule that interacts with the repressor and affects the affinity of the repressor for the operator With the above information, we can now predict the effect that various mutants will have on lac operon gene expression.
