Biology Exam 2: Genetics Flashcards | Quizlet WebA student claims that the lac operon is an example of a mechanism that an organism uses to conserve energy. Evaluate the validity of the student's claim. A. The claim is valid because the lac operon allows a bacterial cell to shut down a metabolic pathway if it is not immediately needed. B. The claim is valid because the lac operon allows a ...
Lac operon labeled
lac operon - Wikipedia The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria.Although glucose is the preferred carbon source for most bacteria, the lac operon allows for the effective digestion of lactose when glucose is not available through the activity of beta-galactosidase. Lac repressor - Wikipedia WebFunction. The lac repressor (LacI) operates by a helix-turn-helix motif in its DNA-binding domain, binding base-specifically to the major groove of the operator region of the lac operon, with base contacts also made by residues of symmetry-related alpha helices, the "hinge" helices, which bind deeply in the minor groove. This bound repressor can reduce … Lac operon- Definition, structure, Inducers, diagram - Microbe Notes Web02/09/2022 · Inducers and the Induction of Lac operon. Normally, E. coli cells make very little of any of these three proteins but when lactose is available it, causes a large and coordinated increase in the amount of each enzyme. Thus each enzyme is an inducible enzyme and the process is called induction.; The mechanism is that the few molecules of …

Chromosomal DNA contains various … Lac Operon : Regulation of Gene Expression in Prokaryotes - Go Life Science Web20/02/2016 · The Lac Operon. Jacob and Monod proposed the lac operon model to explain the regulation of the synthesis of an enzyme, β-galactosidase, the lac operon in e.coli, only when lactose is available as a substrate and Glucose is not available. This was the first study of metabolic regulation based on genetic analysis of the lac system. They called ...
