Which virus chops and shreds cellular DNA inside the nucleus?1 both polio herpes neither What does the poliovirus do in its replication complexes?1 Does its entire life cycle Assembles the capsids Makes capsid proteins Makes copies of its genome Chickenpox is not really a pox family virus.1 True False From which cell part does herpes get its envelope?1 from the nucleus from the ER from the outer (plasma) membrane from the Golgi body 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. Starting the production of immediate early mRNAs. Helping the capsid get out of the nucleus. Chopping and shredding cellular mRNAs Proteins “scissors” (proteases) can cut any protein.1 True False Both polio and herpes are viruses that like to migrate into nerve cells.1 True False Which of these is NOT true of herpes simplex?1 It has several different kinds of glycoprotein spikes. Most people are infected with at least one type of herpes virus. It enters the body through intestinal cells. It assembles its capsids in the nucleus. Polio and herpes are equally destructive to Golgi bodies.1 True False How long can a herpes virus stay in its lysogenic (dormant) stage?1 Until the host reaches adulthood. For several months. For the lifetime of the host. Until the host catches another virus. For almost a year. Which one of these events in the life cycle of herpes occurs outside the nucleus?1 Manufacturing of glycoproteins Assembly of the capsids Replication of the genome Transcription of mRNAs 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. 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. There are many herpes family viruses that don’t infect humans.1 True False Which of these cell receptors does poliovirus use?1 CD4 sialic acid heparan sulfate ACE2 MHC1 CD155 VIRUSES lesson 7: Inside a Capsid VIRUSES lesson 9: The Body Fights Back Back to: VIRUSES lesson 8: Viruses Inside Cells
