Form confers function: Case of the 3’X region of the hepatitis C virus genome

Figure 2 Diverse secondary structure models proposed for the 3'X region of hepatitis C virus genome. A: The 3xSL model[17,18]; B: The 4xSL model[20]; C: The 2xSL model[21]. The region involved in the kissing-interactions is indicated with blue line, the region involved in dimerization is marked with red line; possible alternative folding of separate fragments are displayed as gray rectangles.
