We can decorate the unwound diagram with states in the usual top-down fashion.
In this fashion, the stack is dynamically unwound to the nearest context that can handle the exception.
They occur at unwound base-pair steps (y20x twist) where roll deformations allow additional stacking recovery.
Then we can label the states of the unwound loop diagram as shown in the illustration above.
These bobbins were wound so that thread exiting from the centre of the bobbin unwound freely.
In such complexes, the double helical segment contacting the protein is unwound and its minor groove widened.
Those assurances were given and accepted in good faith, but we discovered—as they unwound—that they did not amount to much.
Many of the contracts it would affect would have to be unwound over a couple of years.
