BIO 203 Chapter 13 Study guide After completing the lecture notes in class and reviewing the notes and related book material, you should be able to Describe/answer/know the following important concepts from this chapter. Define acellular: Acellular infectious particles include: What are some general characteristics that all viruses, viroids and prions share? How big are viruses? Are viruses bigger or smaller than bacteria? Provide some examples of viral diseases: List some shared characteristics that all viruses have: The protein coat of a virion is called a ______________. If a virion has a phospholipid layer around the protein coat it is considered a _________________ virus. The phospholipid layer provides ___________________and _____________________ sites for host cells. Describe the intracellular state of a virus: How are viruses differentiated from one another? What type of nucleic acid may serve as a viral genome? All cells have what type of nucleic acid for their genomes? What accounts for the specificity of viral infections? What is a generalist virus? What types of cells can be infected by a virus? A virus that infects a bacterium is called a _________________________________. What role does a capsid provide for a virus? What are capsids composed of? Describe the three basic shapes of viruses: Describe the shape of a bacteriophage: How is a viral envelope acquired? What role do an envelopes proteins and glycoproteins play? What must a virus depend on for replication? Define lytic replication: List the basic stages of lytic replication: Define lysogeny: Define Prophage: Define induction: What events can cause induction? Compare and contrast lytic and lysogenic replication: Describe how Animal viruses attach to host cells: How are animal viruses and bacteriophages different? Where is a DNA virus replicated in an animal cell? Where is a RNA virus replicated in an animal cell? What type of infections can enveloped viruses cause? Define latent virus: Define provirus: How is a latent virus different than a lysogenic virus? Explain the role of viruses in cancer: Why must viruses be cultured along with other cells for research purposes? Describe the living characteristics of viruses: Describe the nonliving characteristics of viruses: Describe viroids: List the disinfection and sterilization methods that prions are resistant to: How are prions destroyed?
