(D) Viruses are defined as infectious nucleoproteins. A complete virus particle is called a virion, whose main function is to deliver its $DNA$ or $RNA$ genome into the host cell so that the genome can be expressed by the host cell.In a particular virus, either $DNA$ or $RNA$ is the genetic material; both are never present in the same virus.This confirms that $RNA$ can act as the genetic material and transfer hereditary information.Examples include:$(i)$ Double-stranded $DNA$ $(dsDNA)$: Hepatitis $B$ virus.$(ii)$ Single-stranded $DNA$ $(ssDNA)$: Coliphage $\phi X174$.$(iii)$ Double-stranded $RNA$ $(dsRNA)$: Reovirus, Wound tumor virus.$(iv)$ Single-stranded $RNA$ $(ssRNA)$: Tobacco mosaic virus $(TMV)$.
