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