Answer with a diagram, trying to locate these steps: ___ Assembly of viral proteins (e.g. capsid) ___ Entry through endocytosis ___ Attachment to specific receptor ___ Replication of the viral genome (by RNA or DNA polymerase) ___ Translation of mRNA ___ Release of viruses (by apoptosis or exocytosis) 4. Immune defense against viruses occurs in what way (humoral, cellular, other)? Describe by naming the important cells and molecules involved and their relationships. Your answer should be presented via one or more diagrams, inspired by reliable sources, and should include the following keywords: CD4, CD8, cytokine, antibody, B, T, MHC, APC. 5.
