[Differentiated expression of the viral genome in mammalian cells transformed by the Rous sarcoma virus].

In hybridization of 3H-DNA-product of Rous sarcoma virus with the RNA isolated from mammalian cells transformed by the virus concerned, it was found, that the virus-specific RNA, isolated from cryptovirogenic cells RVP-3, differs in nucleotide sequences from virogenic cells XC, XPO and TWERC.
