What is the genome type of Borna virus?

Borna virus has a single-stranded RNA genome with negative sense. This means its genetic material is RNA, not DNA, and it is not double-stranded. Viruses with negative-sense, nonsegmented RNA genomes (like Borna virus) must bring or synthesize an RNA-dependent RNA polymerase to transcribe mRNA from their genome once they infect a cell. That’s why RNA is correct, and DNA or double-stranded RNA options don’t fit.
