12 Subviral Particles Viroids Infectious RNA disrupts metabolism in plants Infectious RNA disrupts metabolism in plantsPrions Misfolded proteins misfold normal proteins in animals Misfolded proteins misfold normal proteins in animals

13 Review Questions 1.What materials are found in every virus? 2.How do viroids and prions vary from virions? 3.What are effective ways to combat retroviruses? 4.How might new viruses emerge?
