A double-stranded RNA virus generates its mRNA using which enzyme?

1. Group III viruses use double-stranded RNA as their genome. 2. The two strands separate, and one of them serves as a template for mRNA. 3. The polymerase that reads that RNA template is an RNA-dependent RNA polymerase encoded by the virus itself. 4. A host DNA-dependent RNA polymerase reads DNA, so it cannot copy an RNA genome. 5. Neuraminidase is an influenza envelope enzyme that releases virions, not a polymerase. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 21 "Viruses", section 21.1 Viral Evolution, Morphology, and Classification_
