AA full capsid and several enzymes
BBoth DNA and RNA copies of itself
CA protein envelope from host lipid
DOne specific RNA and no protein
Answer & Solution
Correct answer: D. One specific RNA and no protein
1. Like a virus, a viroid can reproduce only within a host cell.
2. Unlike a virus, it manufactures no proteins at all.
3. What it does produce is a single, specific RNA molecule.
4. Viroids have no capsid and no envelope, so the options offering either of those contradict what a viroid is.
5. Human diseases caused by viroids have yet to be identified, so their impact is agricultural.
