The genetic material of a virus can be either DNA or RNA The viruses that contain DNA as their genetic material are called the DNA viruses RNA viruses, on the other hand, contain RNA as their genetic material DNA viruses are mostly doublestranded while RNA viruses are singlestranded RNA mutation rate is higher than the DNA mutation rateThe occurrence of double stranded RNAs in biological systems was uncovered in a number of experiments in the early 1960s 7–9 Intriguingly all of the biological systems initially found to be sources for double stranded RNA involved virus infectionIs it singlestranded or doublestranded?
