Evidence for a Ring Structure of Polyoma Virus DNA

Part of the Milestones in Current Research book series (MCR)


The DNA of polyoma (PY) virus has two interesting features: it is unusually resistant to heat or formamide denaturation,1 and it has two distinct components, of sedimentation coefficient 14 and 21, respectively.2 A two-component sedimentation was formerly shown to be a characteristic of the DNA of papilloma virus,3 which is considered a member of the same group of viruses.
