Case 1: RNA Virus Mutation A researcher is studying a new RNA virus. Unlike DNA viruses, RNA viruses mutate more rapidly. The researcher finds that this rapid mutation is linked to the virus’s single-stranded RNA structure. Question 1: Why does the single-stranded nature of RNA contribute to the high mutation rate in RNA viruses? A)
