We have analyzed SV40 specific RNA sequences which are associated with purified viral chromatin. Three discrete size classes of large unprocessed transcripts were identified: 4.8, 3.6 and 3.0 kb. Furthermore, two polyadenylated species of 2.6 and 1.6 kb were found, the latter of which representing mature 16 S mRNA. S, analysis revealed both the presence of spliced and unspliced RNA sequences in transcriptionally active SV40 chromatin.
