Figure 1From: Efficient known ncRNA search including pseudoknotsConsensus secondary structure of tmRNA and the secondary structure described by SCFG (pseudoknots missing). A. Consensus secondary structure of RF00023 (tmRNA) in Rfam. Stacking base pairs in 1 are parallel to base pairs in 2 and 3. 1, 2, and 3 are nested in 4. 2 and 3 form a pseudoknot. B. Secondary structure described by SCFG (pseudoknots missing).Back to article page
