True or false: The coronavirus is a type of RNA virus.

The statement is true because coronaviruses are indeed classified as RNA viruses. They belong to the family Coronaviridae and are characterized by their single-stranded RNA genomes. This classification includes various strains, some of which can cause respiratory illnesses in humans and animals, such as COVID-19, which has garnered significant attention due to its widespread impact. The nature of coronaviruses as RNA viruses plays a critical role in their replication and mutation, influencing their ability to adapt and evolve.

The other options either misidentify the type of virus or suggest nuances that do not apply to the general classification of coronaviruses. For instance, stating it is a DNA virus would be incorrect, as that fundamentally misrepresents its genetic material. Additionally, the suggestion that it is only RNA in certain strains does not capture the consensus that all coronaviruses are classified as RNA viruses in their entirety. Therefore, the correct assertion is that coronaviruses are indeed a type of RNA virus.
