Use this prompt to answer questions 12-19. You discover a new virus that causes ulcers in the mouth and is transmitted through contact with infected saliva.  You name the virus Salivary Emission Ulcervirus, SEU for short.  SEU’s genome is single stranded DNA.  You are able to get an image using electron microscopy (left) and build a model of the virus (right).  After years of work, you find that SUE attaches to host cells using AB-1 as an attachment factor and YZ-2 as a receptor.  You use this information to better understand the tissue tropism of the virus.  You design an experiment to test multiple cell lines and determine if they can be infected by SEU.  Your results are below.

Based on the Baltimore System, SEU is a Class ___ virus.

In order for SEU to successfully infect a cell it must enter the cell via , triggered by the attachment of to the host’s proteins.

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

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

You are having a conversation with your friend and they tell you that there are four domains of life: eukaryotes, prokaryotes, archaea and viruses.  Do you agree with your friend?  Explain and provide evidence to support your answer. (six sentences max)

Use this prompt to answer questions 10-11. To better understand the importance 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.

Entry of the genome into the host’s cytoplasm is triggered by ___.

This Potato virus is a(n) virus
