[Transfer of the genetic information of oncornaviruses by means of tumor cell DNA].

The infection process was reproduced in the culture of chick embryonal cells by means of: a) DNA isolated from chick Rous sarcoma (Carr-Zilber strain); b) DNA from blood cells of chicks with myeloblastosis (strain A); c) DNA from Rous virus malignified (Prague strain) rat cells (XC). Antigenic properties of the virus, transfected with DNA from chick Rous sarcoma, would differ from the original parental strain (Carr-Zilber RSV), that evidences the possibility of a partial transfer of genetic information in transfection. A suggestion is made on four presumable variants of oncornaviruses transfection by means of tumor cells DNA.
