Question

how are viroids different from viruses​

Answer 1

Answer:

Explanation:

A viroid (an infectious RNA molecule) is similar to a virus but not quite the same thing. It's smaller than a virus and has no capsid. A viroid is a coiled, "naked" RNA molecule that can affect a cell. ... Prions (infectious protein particles) have neither DNA nor RNA to transmit infection.

Answer 2

Answer :-

• Viroids are free RNA molecules of low molecular weight without any protein coat while viruses can have either RNA or DNA molecules encapsulated in a protein coat.

• Viroids are smaller in size than the viruses.

• Viroids infect only plants whereas virus infects all types of organisms.

• In viroids, protein coat is absent whereas in viruses a protein covering or a coat called as capsid is present around the genetic material.

Hope it helps u out!!
