Based on physical and chemical determinations, the mnolecular weight of the type 4 adeno-satellite virus is 5.4 X 106 daltons, and the virion contains 1.4 X 106 daltons of DNA. Denaturation and renaturation studies indicate that the viral genome is a single-stranded DNA molecule and that each virion contains either a minus or a plus strand. Upon extraction, the minus and plus strands unite to form double-stranded DNA molecules with no obvious excess of unpaired strands.
