Question

What do viroids And virusoids both lack?

Answer 1

Viruses: These are microscopic infectious agents containing genetic material that is enclosed in a protein capsule called a capsid.

Viroids:

1. Viroids are infectious pathogens that are capable of infecting only plants, thus known as plant pathogens.
2. Structurally, they are smaller than viruses and have circular strands of ribonucleic acids (RNA) with the absence of protein coating.
3. Virusoid DNA is not responsible for coding any protein but capable of replicating RNA.

1. Both viroids, as well as virusoids, lack protein-coding genes.
