D) Viroids
E) Protisits

Question

Quizplus · Accepted Answer

Viroids are small infectious agents that contain a short single-stranded RNA molecule without a protein coat. They are smaller than viruses and can cause disease in some plants. Prions (A) are infectious proteins that can cause neurological diseases in animals, but they do not contain RNA. Viruses (B) are infectious agents that have small pieces of RNA or DNA packaged in a protein coat. Bacteria (C) are microorganisms that have a cell wall, cytoplasm, and genetic material, but they do not contain RNA alone. Protists (E) are a diverse group of eukaryotic organisms, and not all of them are infectious agents.
