RESUMO

Three classes of viral transcripts (18S, 24S, and 33S) were isolated from viral ribonucleoproteins in Sendai virus-infected cells. Hybridization studies with virion minus strand genome RNA demonstrated that the 18S RNA contained transcripts from 60% of the viral genome while the 33S RNA contained transcripts from the entire viral genome. Brief heat of ME2SO treatment of the 33S RNA demonstrated that this RNA was composed of two classes: RNA which continued to sediment at 33S (33S RNA) and 18S RNA aggregates (18S RNA). The 33S RNA was determined to be a transcript from the 40% of the viral genome not protected by the 18S RNA. The aggregated 18S RNA does not appear to be an artifact of isolation.
