Further characterization of the cellular DNA hybridizing with the RNA of Rous sarcoma virus.

Both 70S and 4S RNAs of Rous sarcoma virus (RSV) contain nucleotide sequences homologous to those in cellular DNA. Preparations of these RNAs were found to include some adventitious cellular sRNA. Nevertheless, both 70S and 4S RSV-RNAs were found by competition techniques to contain sequences distinct from those in cellular ribosomal RNA and 4S RNA. Competition experiments also reveal substantial homology between 70S and 4SRSV-RNA. In hybridization experiments performed in formamide at low temperatures, the melting profiles of hybrids between 70S RSV-RNA and cellular DNA, and 4S RSV-RNA and cellular DNA, are essentially superimposable. It is suggested that there are at least two origins of 4S RSV-RNA in RSV-RNA preparations: degradation of 70S RSV-RNA and inclusion of adventitious cellular 4S RNA. The possibility of a specific viral 4S RNA is not excluded.

Hybridization of RNA from Rous sarcoma virus with cellular and viral DNA's.

The RNA of Rous sarcoma virus (RSV) hybridizes with DNA's isolated from all eukaryotes tested (animal and plant) with the possible exception of yeast. Bacterial DNA's show no homology to RSV-RNA. DNA's from the oncogenic viruses, adenovirus type 12 and SV40 show significant homology with RSV-RNA, but those from nononcogenic adenoviruses types 2 and 4 are not homologous.RSV-RNA hybridized to all of the DNA's examined has the same, or a closely similar, base composition. Moreover, the melting temperatures of all of the hybrids analyzed are very similar, further suggesting that a common base sequence in DNA functions in hybridization with RSV-RNA.
