What is the genome type of Equine Morbillivirus?

Morbilliviruses carry a negative-sense single-stranded RNA genome. This means the genetic material is RNA, not DNA, and it requires the virus to bring or encode an RNA-dependent RNA polymerase to transcribe mRNA from the genome after infection. Because of this, the genome cannot be read directly by host ribosomes. Equine Morbillivirus, like other morbilliviruses, has this RNA genome configuration. So the correct answer is RNA. DNA or a DNA–RNA hybrid would imply a DNA component in the genome, which these viruses do not have, and a protein would not represent a genome at all.
