SEU is a(n) [12] virus.

Which of the following steps do NOT have to occur in order for the viral genome of the VMV to enter the host cytoplasm.  Choose all that apply.

Like other enveloped viruses, the glycoprotein responsible for membrane fusion can be divided into three domains.  Match the domain and the fusion peptide with the structures labeled below.

SEU’s capsid symmetry is ___.

Based on the Baltimore System, this is a class __ virus.

From your experiments (results copied again below) you note the limited tissue tropism of SEU.  Based 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.

The viral genome can be packaged using… (choose all that apply).

This virus’ capsid symmetry is ___.

The virus’ envelope is composed of… (choose all that apply)

SEU is a(n) [12] virus.
