Dr. Kister might find the reason why the direction is wrong.

Dr. Kister figured this out on his way to the research club between second floor and first floor.
He told me that if we correct the direction, there will be an interlock,
in order to have an interlock, there must exist two pairs of hydrophobic residues connect with each other,
but when those residues already connect to it's consicutive strand, it's not possible to connect to the strand on the other strandon, that's why it must stay out of the interlock and be on the edge.
