Question: what is the difference between a dna virus and an rna virus?
Answer: DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. RNA viruses have typically ssRNA, but may also contain dsRNA. ... The genetic material of ssRNA(+) viruses is like mRNA and can be directly translated by the host cell.
