Subword Structure of Ineffective Subword-unique Motifs. A subword tree constructed in the same manner as Figure 3, but for motifs associated with ineffective antisense suppression. In this population of motifs, nodes are grouped into two main trees, one rooted with "A", one rooted with "T". Surprisingly, despite the lower Gibbs free energy associated with its presence, a third tree rooted at "G" was found within this population of motifs as well.
