Viroids: Characteristics and Explanation of the answer
Viroids are infectious agents that cause diseases in plants. They were first discovered in 1971 by Theodor Diener. Viroids are composed of a single-stranded RNA molecule and do not have a protein coat. They are smaller than viruses and cannot replicate independently. Instead, they depend on the host plant's cellular machinery to replicate and spread.
Characteristics of Viroids:
1. RNA molecules: Viroids are composed of a single-stranded RNA molecule.
2. Small size: Viroids are smaller than viruses. They range in size from 246 to 401 nucleotides.
3. No protein coat: Viroids lack a protein coat or capsid, which is a defining characteristic of viruses.
4. Replication: Viroids depend on the host plant's cellular machinery to replicate and spread.
5. Disease-causing agents: Viroids are infectious agents that cause diseases in plants.
Explanation of the answer:
The correct answer is option 'C'. Viroids do not have a protein coat, which is a defining characteristic of viruses. Viroids are composed of a single-stranded RNA molecule and cannot replicate independently. They depend on the host plant's cellular machinery to replicate and spread. Viroids are infectious agents that cause diseases in plants, and they are smaller than viruses.
