The tryptophan (Try) operon is a genetic system found in bacteria that regulates the production of enzymes involved in the biosynthesis of the amino acid tryptophan, where the presence of tryptophan represses the expression of the operon by binding to a regulatory protein and preventing transcription of the genes.

Background: Nepal has an incredible geographic diversity with an altitude ranging from 50m to highest peak in the world (Mt. Everest, 8848m) from sea level and is topographically divided into three regions: The Terai, the Hilly and the Himalayan regions. The Himalaya and its foothills make up the northern border of the country and represent
