Imagine that a researcher discovers a new type of virus. This virus contains single‑stranded RNA with "negative" sense. Consider the image. Which statement is true regarding this virus? According to the Baltimore system, this virus would be classified as a type V virus. Based on the presence of single‑stranded RNA, this virus is likely similar to HIV. According to the Baltimore system, this virus would be classified as a type IV virus. This virus must use reverse transcriptase to produce mRNA.
