Fig. 2From: SparseRNAfolD: optimized sparse RNA pseudoknot-free folding with dangle considerationWe show in graphical format each of the recursions. The notation for these figures is as follows: a solid horizontal line signifies the RNA sequence, a solid arc denotes a base pair, and dashed arcs represent regions. Fixed endpoints of a region are depicted by red circles, while blue squares indicate unpaired elements used for boundary determinationBack to article page
