Viroids typically infect plant, while prions typically infect nervous system.
Is this correct? thanks!
Yes, your statement is correct. Viroids are small, circular RNA molecules that can infect plants. They do not have a protein coat like viruses do, and they replicate within the cells of the plant, causing various diseases.
On the other hand, prions are misfolded proteins that can cause neurodegenerative diseases in animals, including humans. They can affect the central nervous system, cause protein aggregation, and ultimately lead to the damage and death of brain cells.
To arrive at your conclusion, you could have researched the definitions and properties of viroids and prions, their modes of infection, and the types of organisms they affect. This information is readily available in scientific literature and reputable online sources.
