Gene Regulation Answers

I have used such an approach In an attempt to answer the question, why positive and negative mechanisms of gene regulation In what follows I shall not be concerned with the mathematical methods per se. Instead, my approach will be to outline the principal steps In the development of the theory and then emphasize the most Importamt results. 

Answer E. TBP and CBP participate in eukaryotic gene transcription and mRNA translation, respectively. CAP regulates the expression of prokaryotic lactose operons. ACP is involved in fatty add synthesis. 

In no model pheromone biosynthetic system is the molecular mechanism of hormonal regulation completely understood. The mechanism of action of JH and the nature of its receptor remain one of the mysteries of insect science, and the clear-cut action of JH by itself in inducing specific genes in pheromone production in bark beetles offers an excellent model for study. A better understanding of the PBAN receptor and the second messenger system it triggers as well as the steps regulated in pheromone biosynthesis is also needed. The next several years should see some of the key questions answered in model insects.
