Modelling a DNA Walker
The feet are intended to bind to adjacent sites on a single-stranded track. The binding sites overlap, meaning that the feet compete for binding to the track. As a consequence, a single-stranded region of one foot or the other is always exposed. A fuel strand that is also present in solution can bind to either exposed toehold.
