Although viruses may contain their genome within an enclosed space (much like the nucleus of a cell), it is considered neither eukaryotic nor prokaryotic. TrueCorrect!Correct!False 5 / 5 ptsQuestion 2 Your Answer: Describe the two basic components of a virus. Two basic components of a virus are; 5/1/22, 6:15 PM M6: Module 6 Exam - Requires Respondus LockDown Browser + Webcam: Essential Microbiology with Lab-2021-Bowman The genomic material that comprises of either DNA or RNA A capsid, a membraneus like protective structure that contains genetic materials similar to those of the eukaryotic cell A virus has (1) genomic material comprised of either DNA or RNA and (2) a capsid, a membrane-like protective structure that contains the genetic material, similar to the nucleus of a eukaryotic cell. 3 / 3 ptsQuestion 3 Your Answer: The envelope surrounds the _________ of some viruses. Capsid capsid 2 / 2 ptsQuestion 4 True or False. You would expect to see a viral envelope on a virus infecting a bacterial cell.True False Correct!Correct! 5/1/22, 6:15 PM M6: Module 6 Exam - Requires Respondus LockDown Browser + Webcam: Essential Microbiology with Lab-2021-Bowman False. The overwhelming majority of animal viruses are enveloped whereas the majority of plant or bacteria-infecting viruses are not. 3 / 3 ptsQuestion 5 Your Answer: Rank the following viruses based on their size from largest to smallest: Paramyxovirus Poliovirus Smallpox virus Smallpox virus(~200nm) --- Paramyxovirus(100-150nm) --- Poliovirus(~30nm) Smallpox (~200nm) Paramyxovirus (100-150nm) Poliovirus (~30nm) 2 / 2 ptsQuestion 6 True or False: Viral replication occurs after it attaches and enters the host cell. True Correct!Correct! True. The viral genome is never replicated before attachment and entry. 5/1/22, 6:15 PM M6: Module 6 Exam - Requires Respondus LockDown Browser + Webcam: Essential Microbiology with Lab-2021-Bowman 5 / 5 ptsQuestion 7 Your Answer: Place the following viral life cycle steps in order beginning with viral attachment and provide a description of each step. Uncoating: Release: Replication: Attachment: Entry: New infection: Attachment -- Entry -- Uncoating -- Replication -- Release -- New Infection Attachment; the viral receptors attaches to te host protein on the cell surface Entry; the virus fuses with the membrane of the host cells and enters the cell Uncoating; The viral capsid disassembles Replication; the viral genome is the blue print that replicates itself Release; New viral particles are produced and then released New Infection; the released new viral particles that exists the cell go ahead and infect new cells 5/1/22, 6:15 PM M6: Module 6 Exam - Requires Respondus LockDown Browser + Webcam: Essential Microbiology with Lab-2021-Bowman 3- Uncoating: the viral capsid disassembles 5-Release: New virus particles are produced and leave the cell 4-Replication: the viral genome is the ‘blueprint’ to make copies of itself 1-Attachment: viral receptors bind to host proteins on the surface of the cell 2-Entry: the virus fuses with the host membrane and enters the cell 6-New infection: newly produced viruses that left the host cell now go on to infect new cells.
