Why would viruses need to be cultured? What is a latent viral infection? What are cytopathic effects (know examples). Know characteristics of viroids and prions. What are they?

The viral protein (X) appears to play a role in the export of the viral genomes to the cytoplasm. Protein X brings viral DNA to the cytoplasm and returns back to the nucleus after genome export is complete. Researchers have developed a new drug for the virus. Following treatment with the new drug, the viral protein stays in the nucleus and cannot export the viral genomes. What is the most plausible and logical function of the drug? Use your knowledge of nuclear transport to answer this question. O A. The drug inhibits the binding of the viral protein and the viral genomes to the import receptor. B. The drug inhibits the binding of Ran-GTP to the nuclear export receptor in nucleus. C. The drug promotes the Ran GAP activity. D. The drug blocks the NLS on the viral protein.arrow_forward
