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. Until the host catches another virus. For the lifetime of the host. For almost a year. For several months. 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 virus chops and shreds cellular DNA inside the nucleus?1 herpes both polio neither 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. What does the poliovirus do in its replication complexes?1 Makes capsid proteins Makes copies of its genome Does its entire life cycle Assembles the capsids Which of these is NOT true of herpes simplex?1 It assembles its capsids in the nucleus. 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. 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. Chopping and shredding cellular mRNAs Starting the production of immediate early mRNAs. Chickenpox is not really a pox family virus.1 True False Which of these cell receptors does poliovirus use?1 ACE2 CD155 sialic acid MHC1 CD4 heparan sulfate Polio and herpes are equally destructive to Golgi bodies.1 True False From which cell part does herpes get its envelope?1 from the Golgi body from the outer (plasma) membrane from the nucleus from the ER Which one of these events in the life cycle of herpes occurs outside the nucleus?1 Replication of the genome Manufacturing of glycoproteins Assembly of the capsids Transcription of mRNAs 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 leaves the cell by budding. It has a small genome.
