FIG. 6.
cis-acting sequences for RNA synthesis on the 3′ end of plus-strand HCV RNA by NS5B. (A) The structure of RNA templates used for RdRp assays. (B) The products were run on an 8 M urea–5% polyacrylamide gel. The positions of the 98-nt template [HCV-X(+)] and the full-length 3′-UTR HCV [HCV-3′(X)] are indicated with arrowheads. The templates used for the reactions are indicated above the gel.
