Multiple Choice

Rhinovirus virion is best described as

Rhinovirus is a small picornavirus with no lipid envelope, an icosahedral capsid, and a positive-sense single-stranded RNA genome. That means the virion is naked, has icosahedral symmetry, and carries +ssRNA that can act directly as mRNA once inside the host cell. These features distinguish it from enveloped viruses, which would have a lipid envelope, and from viruses with helical capsids or with dsRNA or negative-sense RNA genomes.
