FIG. 3.

(A) Nucleic acids isolated from RsRNAV01 (lane 3) and RsRNAV06 (lane 4). RNA molecular size markers are shown in lanes 1 and 5, and Sendai virus RNA (15.8 kb) is shown in lane 3 to estimate the lengths of viral RNAs. A smaller faint band (0.6 kb) is also observed (arrowhead). (B) Nucleic acids extracted from RsRNAV06 without (lane 2) or with (lane 3) DNase I treatment at 37°C for 1 h. No host DNA is found in lane 3 (arrow). RNA molecular size markers are shown in lane 1. Smaller RNA bands (1.5 and 1.2 kb) extracted from RsRNAV particles are also observed.
