AZT (zidovudine) inhibits the synthesis of the HIV virus RNA because AZT resembles substrate molecules. Which kind of inhibition is most likely taking place in this reaction?

How might two drugs interact with each other through actions on the CYP450 enzyme system?

How does sulfanilamide work as a bacteriostatic drug? Come up with a way that a strain of bacteria can avoid the effects of sulfanilamide that does not involve destroying or inactivating the drug.

Human cells contain a protein that binds to the 5′ triphosphate groups of RNA. Explain why this protein would be part of the defense against viral infection.

The structure of a prodrug used for treating people with HIV virus (human immunodeficiency virus) and AIDS is shown below. This molecule is a precursor of a protease inhibitor that competitively inhibits HIV protease due to its resemblance to the proteolytic site of the enzyme. Which process in the viral life cycle does this inhibitor target directly ?   Group of answer choices a. viral protein processing for making new viruses b. viral mRNA synthesis c. viral DNA integration into the host cell DNA d. viral DNA synthesis

A transduction experiment was carried out to map the his and leu genes, which are involved in amino acid biosynthesis, of E. coli using a his+ leu+ donor and a his- leu- recipient. his+ leu- transductants will grow on agar media with: OA lacking histidine, containing leucine O B. containing histidine, containing leucine OC containing histidine, lacking leucine O D.a and b are correct O E. a, b and c are correct
