To answer: Why dengue, yellow fever, and malaria are re-emerging in areas where they have long been eradicated. Introduction: Dengue is a disease caused by a family of viruses and the vectors for the transmission of this disease is mosquitoes. Yellow fever is spread by female Aedes aegypti and it is a “viral disease” that occurs for short duration. Malaria is caused by parasitic protozoans belonging to the Plasmodium type and are transmitted by mosquito vector. Once an infected mosquito bites a human, then the parasite further multiply in the host body.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

From your previous experiment, you found that this enhancer activates stripe 2 of eve expression. When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?

What experiment could you do to see if the maternal gene, bicoid, is sufficient to form anterior fates?

You’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene. Describe an experimental technique you would use to find out where this particular eve enhancer is active.
