Abstract
The total intracellular deoxyribonucleic acid (DNA) from baby hamster kidney cells abortively infected with 3H-adenovirus type 12 was analyzed in dye-buoyant density gradients. Between 10 and 20% of the cell-associated radioactivity derived from viral DNA bands in a density position which is 0.043 to 0.085 g/cm3 higher than that of viral DNA extracted from purified virions. The DNA in the high-density region (HP-fraction) is almost completely absent when DNA, ribonucleic acid (RNA) or protein synthesis is chemically inhibited in separate experiments. The HP-fraction is not found when the virus does not adsorb to and enter the cell. The DNA in the HP-fraction appears as early as 2 hr after inoculation. At 2 hr after infection, the HP-fraction is present both in the nucleus and the cytoplasm. This DNA hybridizes exclusively with viral DNA and sediments at approximately the same rate in both neutral and alkaline sucrose density gradients. Electron microscopy has revealed no circular DNA molecules in this fraction. Evidence indicates that the viral DNA in the HP-fraction exists in a complex with protein and possibly RNA. The protein component of the complex is resistant to enzymatic digestion, whereas the complex is susceptible to ribonuclease treatment. Digestion with deoxyribonuclease reduces the amount of DNA found in the HP-fraction. The structure and biological function of this complex are currently being investigated.
