well they allow the process of photosynthesis which makes food for the plants which gives us air so we can breathe
Answer:
The correct answer is b The regulator gene falls off the operator and the structural genes get transcribed.
Explanation:
Tryptophan operon contain3 regulatory genes and 5 structural genes.when adequate amount of tryptophan is present at that time the tryptophan binds to the repressor molecule encoded by tryp R gene.Thus Tryptophan act as co repressor .The repressor molecule bound to tryptophan interacts with operator region resulting in blocking the expression of structural genes.
But when tryptophan is absent at that time repressor molecule cannot function.As a result the repressor molecule fall off from the operator and structural genes get transcribed.
