RNA and DNA viruses, referring to the type of nucleic acid they use to store genetic information, are two very distinct groups—probably more evolutionary distant than a lion and a snake. That’s why researchers were so surprised when they found a DNA virus sequence encoding a protein only ever found in RNA viruses. The sample came from a Lassen Volcanic National Park hotspring, where viruses prey on the bacteria living in the acidic water.
