Explain why HIV is classified as a retrovirus. Correct Answer Contains reverse transcriptase enzyme that converts RNA to DNA within the host cell, then back to RNA. Discuss the impact of HIV upon the immune system in regard to T-helper cells (T4, CD4). Correct Answer Leads to low levels of CD4 cells because they are primary target cells for the virus. Destroys through apoptosis or infected bystander cells which lead to direct killing of these cells by the immune system. Differentiate HIV ...
