Frоm yоur experiments (results cоpied аgаin below) you note the limited tissue tropism of SEU. Bаsed on this information and your knowledge of the viral infection cycle, explain why the SEU is able to infect some cell lines, but not others. To completely answer the question you must address the prompts below. Please label your answers A. through E. List the steps of the infection cycle. (five words max) Identify which step(s) of the infection cycle determines host cell susceptibility. Explain your answer. (2 sentences max) Identify which step(s) of the infection cycle determines host cell permissiveness. Explain your answer. (2 sentences max) Determine if each cell line (mouth, tongue and heart) is susceptible and/or permissive and explain your reasoning for each.

To better understаnd the importаnce of MRV's glycoprotein in the virulence of the virus, researchers have produced mutant viruses with amino acid changes in glycoprotein and tested the virulence of the virus using the end-point dilution assay. The wildtype virus (WT) has no mutations, C virions have mutations in the cytoplasmic tail, E virions have mutations in the ectodomain and F virions have mutations in the fusion peptide. The results from the end-point dilution assay for each virus is shown below.
