FIGURE 1.

Sequences of the simulated molecules. Left panel: bacterial (E. coli) 5S rRNA Loop E; right panel: spinach chloroplast 5S rRNA Loop E. Symbols identifying non-Watson-Crick basepairs were previously introduced (Csaszar et al., 2001) and are as follows: Circles represent Watson-Crick edges; squares represent Hoogsteen edges; and triangles represent Sugar-edges. Open symbols represent trans and filled symbols cis basepairs. Filled symbols labeled with B indicate cis bifurcated pairs and those labeled with W indicate water-inserted basepairs.
