A man was brought to the hospital showing "pneumonia"-like symptoms.They took the viral load and determined this to be the new RNAretrovirus infecting lung cells. Since antibodies were unavailable, doctorsdecided to treat him with drugs. Which of the following would mostbenefit the patient?A. Drug A is an inhibitor of the binding of 4OS with 60S ribosome of the lungcells.B. Drug B is a structural analogue of the viral peptide that binds to the receptorof the host cell enabling viral entry into the cell.C. Drug C is a polar molecule that inhibits the lytic enzymes activated upon viralinfection.D. Drug D is an inducer of a proteolytic enzyme.E. Drug E is a steroid that binds at the regulatory site of a gene causing thesynthesis of a repressor that binds at the gene site for the receptor.

Discuss the life cycle of HIV. Include in your answer a discussion of HIV genes, pay particular attention to the significance of the HIV REV gene.
Indicate whether the following sentences is either True or False and CORRECT the wrong sentences ( please answer the two questions 1 and 2) : 1. Simian Virus 40 (SV40) is an example of is a circular ssDNA belong to Polyomavirus, was first isolated from primary cell cultures derived from rhesus monkey kidneys, and activates p53. 2. SARS-COV-2 is an enveloped, icosahedral virus that is surrounded by a lipid bilayer and causes COVID-19 pandemic .
An icosahedral virus has a triangulation number of 6. What is the total number of subunits in one viral particle?
Which of the following is the most likely explanation for an individual who lacks CCR5 as a result of a homozygous defect in the CCR5 gene becoming infected with HIV? a. The mutated CCR5 genes reverted to the normal form, rendering macrophages susceptible to macrophagetropic HIV variants. b. The macrophage-tropic HIV variant entered host cells using CD4 alone. c. The viral nucleic acid alone was taken up by cells, as in cell transformation by bacterial DNA. d. The individual had received a transplant of HIV-infected cells expressing normal CCR5. e. The primary infection involved a lymphocyte-tropic strain of HIV that used CXCR4 as its co-receptor.
You discovered a novel virus causing a new disease. Briefly describe how will you go about characterizing it to prove that it is indeed a novel virus.
Define the terms "latency" and "lysogeny" as they refer to viruses. Describe at least TWO ways these two processes are similar. Describe at least TWO ways these two processes are different.
Rhinoviruses, the most common cause of colds, do not have a lipid envelope. Compared to enveloped viruses, these and other nonenveloped viruses tend to remain infectious outside the body longer, are more likely to be spread by contact with surfaces, and are less likely to be rendered harmless by exposure to hand sanitizer or hand washing. Explain how the lack of an envelope could contribute to these characteristics.
