title: RNA-dependent DNA polymerase activity in preparations of a mutant of Newcastle disease virus arising from persistently infected L cells.
abstract: RNA-dependent DNA polymerase activity was found in peparations of a mutant of Newcastle disease virus. The enzyme activity was not found in wild-type virus preparations.
