Mapping the transcription site of the SV40-specific late 16 S mRNA

Abstract
This paper describes the purification of polysomal RNA from SV4O-lytically infected CVl (monkey) cells and separation of the two distinct classes of SV4O-specific mRNA sedimenting at 16 S and 19 S. These classes have been hybridized with the whole SV4O DNA genome as well as with the SV40 Hind fragments. The results have permitted the mapping of SV40-specific late 16 S mRNA from approximately 0.945 to 0.175 map units.
