A novel virus is discovered with a single-stranded nucleic acid genome. Treatment with RNase H significantly reduces its infectivity, while DNase I has no effect. Further analysis reveals the presence of short RNA fragments complementary to the genome. What can be most confidently inferred about the viral genome?
It is a single-stranded RNA virus that replicates through a DNA intermediate.
It is a single-stranded DNA virus that replicates through an RNA intermediate.
It is a single-stranded RNA virus that replicates through a double-stranded RNA intermediate.
It is a double-stranded RNA virus.
