Viruses can have either DNA or RNA as their genetic material, but not both. Viruses that contain DNA are referred to as DNA viruses, while those with RNA are called RNA viruses.
There are different types of DNA viruses, including single-stranded DNA (ssDNA) viruses and double-stranded DNA (dsDNA) viruses. Similarly, RNA viruses can also be single-stranded or double-stranded. The type of genetic material plays a significant role in how the virus replicates and how it interacts with host cells.
In summary, some viruses have DNA, while others have RNA, and each type has its own characteristics and mechanisms of infection.
