What is attenuator in trp operon? - Daily Justnow

The trp operon is a group of genes that are transcribed together, encoding the enzymes that produce the amino acid tryptophan in bacteria. The trp operon was first characterized in Escherichia coli, and it has since been discovered in many other bacteria. The operon is regulated so that, when tryptophan is present in the environment, the genes for tryptophan synthesis are repressed. WebPostprandial somnolence (colloquially known as food coma, after-dinner dip, and postprandial sleep, or by the African-American Vernacular English term the itis [1]) is a normal state of drowsiness or lassitude following a meal.
