Figure 2. One adapter guides many sequences.
Multiple RNA-sequences can be guided differently by one RNA-adapter. Shown are the unfolded RNA-sequences, their original secondary structure (outer panels) and the guided secondary structures (middle panel) when the adapter (shown at the top) binds to the binding sites shown in red. RNA-sequences are co-evolved with the adapter, such that all sequences can code for two distinct functional structures, coding for 18 target structures in total.
