I'd say an <span>endocrinologist would be the best answer.</span>
Stratovolcanoes have relatively steep sides and are more cone-shaped than shield volcanoes. ... The lava therefore builds up around the vent forming a volcano with steep sides. Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma
O, S & Te. I know that’s three. But I think that all three have similar reactivity
Answer:
The correct answer is Tryptophan binds with the repressor allowing it to attach to the operator site,blocking the RNA polymerase.
Explanation:
Tryptophan operon contain 3 regulatory genes and 5 structural genes.The structural genes encodes enzymes for tryptophan biosynthesis.
The expression of tryptophan operon is tightly regulated by the the cellular level of amino acid tryptophan.
When the tryptophan level is high at that time the tryptophan bind with the repressor protein encoded by regulatory tryp R gene and then the repressor tryptophan complex binds to the operator region thus preventing the RNA polymerase enzyme to exert its action.
