How does the tryptophan operon work
WebThe trp operon produces products that are used to manufacture an amino acid, tryptophan. The pathway controlled by the trp operon is an example of an anabolic pathway. The lac operon controls a catabolic pathway, one that breaks down complex molecules to release energy for biological work. WebQuestion: 8. c) Describe how the cell "knows" the current environment conditions in a and b above, by DRAWING a simple cartoon of the trp repressor (in a) and the CAP protein and the LAC repressor (in b). For each state whether it is an activator or a repressor and label its active site and its allosteric site. State what can bind at each site.

WebOperons can be defined as multiple genes that are transcribed together, so yes in the absence of splicing there is a single mRNA produced. There are sequences between the genes in a prokaryotic operon called "ribosome binding sites" (RBSs) that recruit ribosomes to start translation of each gene separately. WebIn Canada, tryptophan is sold as a prescription drug to treat mood disorders (such as bipolar disorder, depression). Learn more about this drug here . 1 . This is a generic drug. The …
WebExplanation: The tryptophan operon contains a gene trp R which synthesizes mRNA for a regulatory protein. This protein binds to tryptophan molecule and further interacts with the operator of the trp operon, thus effectively blocking transcription of the gene. Which protein does the LacI gene code for? WebDec 24, 2024 · The trp operon is activated when tryptophan levels are low by dissociation of the repressor protein to the operator sequence which allows RNA polymerase to transcribe the trp genes in the operon. Key Terms repressor: any protein that binds to DNA and thus regulates the expression of genes by decreasing the rate of transcription
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.
