Closed-circular proviral DNA of Moloney leukemia virus has been purified from a 107 excess of cellular and mitochondrial DNA. The DNA can be visualized in the electron microscope and has the contour length of a molecule with a molecular weight of about 5.5 × 106. Electron microscopic observation of a hybrid between viral RNA and this circular DNA confirms the viral origin of this molecule.
