==== Comments ====

  • The delta between the MFE and the hairpins form is both low (hopefully helping the targeted 'pseudo-switching' behavior) and large enough to make it clear that the experiment failed if the 'pseudo-switching' should not occur at all.
  • The formation of either of the hairpins (and its possible kissing complex forming) should result in the other hairpin forming as well.
  • The form with the hairpin sequences forming a stack is comparatively unlikely (high kcal delta)

Coaxial stacking is not predicted to occur, but the hairpins (marked in white) seem to be predicted to stay distant from each other.
