The nucleic acid is usually double stranded DNA dsDNA but may also be single stranded DNA ssDNA . DNA viruses belong to either Group I or Group II of the Baltimore classification system for viruses. Single stranded DNA is usually expanded to double stranded in infected cells. Although Group VII viruses such as hepatitis B contain a DNA genome, they are not considered DNA viruses according ... others have been described since most have head tail morphologies and linear double stranded DNA ... on the basis of morphology rather than DNA sequence similarity.
