DNA folds into a 3D Wazir Tour!
According to a recent article in Science Daily, or at least the illustration accompanying it, DNA folds into a 3D wazir tour, similar to the 2D examples shown in my drawing alongside. These fractal-type diagrams occur at the end of a section of my Knight's Tour Notes website on Wazir Tours. For those not familiar with the terminology, a "wazir" is a chess piece that moves just to the adjacent square, like a single-step rook, or as in a king's non-diagonal move. A tour of course is a journey or path that visits all the squares of the board once only, without backtracking over any squares already visited.
