WebThe lac operon is only in E. Coli, and lactose intolerance is about your stomach's ability to break down lactose using lactase. A certain gene on chromosome 2 initiates production of lactase, the enzyme that digests lactose. This enzyme, normally present in the small intestine, grabs onto lactose and breaks it into a simpler form. WebFeb 10, 2024 · When tryptophan is not present in the cell, the repressor by itself does not bind to the operator; therefore, the operon is active and tryptophan is synthesized. However, when tryptophan accumulates in the cell, two tryptophan molecules bind to the trp repressor molecule, which changes its shape, allowing it to bind to the trp operator.

WebA typical operon consists of a group of structural genes that code for enzymes involved in a metabolic pathway, such as the biosynthesis of an amino acid. These genes are located contiguously on a stretch of DNA and are under the control of one promoter (a short segment of DNA to which the RNA polymerase binds to initiate transcription).
