FIG 1.

Assignment of radiolabeled FHV RNA replication products. Total radiolabeled RNA products were resolved alongside radiolabeled in vitro-transcribed single-stranded FHV RNA1 and RNA 2 (A) or nuclease-digested FHV replication (Rep.) products (B). RNase A digests ssRNA, RNase H digests DNA:RNA hybrids, and micrococcal nuclease digests single-stranded and double-stranded RNA and DNA. The doublet for dsRNA1 was assigned based on resistance to RNase A digestion and increased size in comparison to ssRNA1 and was consistently observed throughout all experiments.
