Figure 3. A case study for RNA design – Kyurem 7.
[A] A near-miss sequence design for Kyurem 7 (see Figure 2B) was designed by a player-created bot and misfolds only in one stem (red). [B] A successful solution with only afew base changes (green). [C] A slight variation in the Kyurem 7 target secondary structure has only minor changes in the lengths of the multiloops, but is much easier to solve due to the availability of low-energy designs for the expanded multiloops. Nucleotides are colored by base, with A in yellow, U in blue, G in red and C in green. Minimum free energy structures and loop energies (in kcal/mol) are based on the Turner 1999 parameters.
