Chickenpox is not really a pox family virus.1 True False Which of these is NOT true about poliovirus?1 It leaves the cell by budding. It has a small genome. It has an IRES region at the 5 prime end of its RNA. It doesn't carry any protein tools in its capsid. Which of these cell receptors does poliovirus use?1 sialic acid heparan sulfate CD4 MHC1 ACE2 CD155 How long can a herpes virus stay in its lysogenic (dormant) stage?1 For almost a year. Until the host catches another virus. For the lifetime of the host. Until the host reaches adulthood. For several months. Polio and herpes are equally destructive to Golgi bodies.1 True False Which of these is NOT a job done by one of herpes’ tegument proteins?1 Helping the capsid get out of the nucleus. Chopping and shredding cellular mRNAs Attaching to a receptor on the surface of a cell. Starting the production of immediate early mRNAs. Which one of these events in the life cycle of herpes occurs outside the nucleus?1 Assembly of the capsids Replication of the genome Transcription of mRNAs Manufacturing of glycoproteins From which cell part does herpes get its envelope?1 from the Golgi body from the ER from the nucleus from the outer (plasma) membrane Which virus chops and shreds cellular DNA inside the nucleus?1 neither polio herpes both Both polio and herpes are viruses that like to migrate into nerve cells.1 True False What does the poliovirus do in its replication complexes?1 Assembles the capsids Makes capsid proteins Does its entire life cycle Makes copies of its genome Which of these is NOT true of herpes simplex?1 It has several different kinds of glycoprotein spikes. It assembles its capsids in the nucleus. Most people are infected with at least one type of herpes virus. It enters the body through intestinal cells. Why does herpes stop the ER from making MHC1 flags?1 So the infected cell can't alert immune system cells about the viral activity going on inside. So more ATP energy will be available for making viral proteins. So the cell will lose its ability to identify itself. There are many herpes family viruses that don’t infect humans.1 True False Proteins “scissors” (proteases) can cut any protein.1 True False VIRUSES lesson 7: Inside a Capsid VIRUSES lesson 9: The Body Fights Back Back to: VIRUSES lesson 8: Viruses Inside Cells
