title: RNA-dependent DNA polymerase activity in intracytoplasmic type-a particles of mouse mammary tumors.
abstract: Intracytoplasmic type-A particles isolated from mouse mammary tumors and purified by repeated gradient centrifugations exhibit both endogenous and exogenous (template-stimulated) RNA-dependent DNA polymerase activities. The enzyme has a preference for magnesium ions.
