[Hybridization analysis of the viral sequences in the DNA of a hamster Rous sarcoma].

The nuclear genome of Syrian hamster virrion non-producer tumor contains the Rous sarcoma virus-specific nucleotide sequences. The information complexity of the proviral DNA from its tumor is similar to that for the DNA of Rous chicken sarcoma. The proviral DNA both in the hamster and chicken tumor consists of moderately reiterated and unique sequences. The avian oncornavirus-specific sequences are absent in the DNA of normal hamster tissue.
