1 Double Stranded RNA Virus: The double-stranded (ds)RNA viruses represent a diverse group of viruses that vary widely in host range (humans, animals, plants, fungi, and bacteria), genome segment number (one to twelve), and virion organization (T-number, capsid layers, or turrets). The RNA or DNA synthesis abilities of the cell produce the virus's DNA or RNA. 2  2. â¢ Assembly takes place in the cell when the newly created viral proteins and nucleic acid combine to form hundreds of new virus particles.
