comparison of the dna sequences at the sv40-cell junctions in svre9 and svre17 cells with those of a previously characterized viral insertion from sv14b cells shows that no specific viral or cellular sequences occur at sv40-cell junctions and that the cellular dna sequences adjacent to integrated sv40 dna do not display the direct repeat structure characteristic of transposons and retrovirus proviruses .
