Subviral ParticlesViroids Infectious RNA disrupts metabolism in plants
Prions Misfolded proteins misfold normal proteins in
animals

Review Questions1.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?
