FIG. 7.

Subgenomic-length negative strands remain in transcriptionally active complexes after cycloheximide treatment. The gels in Fig. 6 were scanned by AMBIS RIS for 12 h, and radioactivity in each mRNA and RF RNA was quantified by counting. (A) Total mRNA synthesis before (○) and after (●) cycloheximide treatment; (B) total RF RNA synthesis before (○) and after (●) cycloheximide treatment; (C) effect of cycloheximide treatment on mRNA 1 (○), RF RNA 1 (●), mRNA 7 (□), and RF RNA 7 (■) synthesis.
