title: [Molecular biology criteria for functioning of the genome of Rous sarcoma virus in transformed rat XC cells].
abstract: Integration, transcription and translation of Rous sarcoma virus (RSV) genome was analyzed in transformed rat fibrosarcoma XC cells (non-virus producing). About ten copies of RSV genome were integrated into the host cell genome. Different types of viral RNA were identified in the cytoplasmic fraction whose sedimentation values were nearly the same as for RSV-specific RNA in virus-producing chicken cells. These RNA were translated in polysomes and directed synthesis of gag, env and src proteins. In comparison to chicken cells in transformed XC cells the cleavage of gag precursor Pr 76gag could not be observed.
