Which of these is NOT true about poliovirus?1 It leaves the cell by budding. It has an IRES region at the 5 prime end of its RNA. It has a small genome. It doesn't carry any protein tools in its capsid. Why does herpes stop the ER from making MHC1 flags?1 So more ATP energy will be available for making viral proteins. So the infected cell can't alert immune system cells about the viral activity going on inside. So the cell will lose its ability to identify itself. Which virus chops and shreds cellular DNA inside the nucleus?1 neither polio herpes both Proteins “scissors” (proteases) can cut any protein.1 True False Polio and herpes are equally destructive to Golgi bodies.1 True False Which of these cell receptors does poliovirus use?1 heparan sulfate CD155 MHC1 sialic acid CD4 ACE2 How long can a herpes virus stay in its lysogenic (dormant) stage?1 For several months. For almost a year. Until the host catches another virus. For the lifetime of the host. Until the host reaches adulthood. There are many herpes family viruses that don’t infect humans.1 True False Chickenpox is not really a pox family virus.1 True False Both polio and herpes are viruses that like to migrate into nerve cells.1 True False Which of these is NOT a job done by one of herpes’ tegument proteins?1 Attaching to a receptor on the surface of a cell. Helping the capsid get out of the nucleus. Starting the production of immediate early mRNAs. Chopping and shredding cellular mRNAs What does the poliovirus do in its replication complexes?1 Makes capsid proteins Does its entire life cycle Makes copies of its genome Assembles the capsids Which one of these events in the life cycle of herpes occurs outside the nucleus?1 Manufacturing of glycoproteins Assembly of the capsids Transcription of mRNAs Replication of the genome From which cell part does herpes get its envelope?1 from the ER from the outer (plasma) membrane from the Golgi body from the nucleus Which of these is NOT true of herpes simplex?1 It has several different kinds of glycoprotein spikes. It enters the body through intestinal cells. It assembles its capsids in the nucleus. Most people are infected with at least one type of herpes virus.
