Figure 6.
Detecting assembly defects using CHA circuits. In the perfectly formed mAP structure (a), the toehold (shown in red) is only partially exposed, whereas defects near the hybridization junction may fully expose the toehold (b). The hybridization defects can be mimicked by introducing point mutations on the mOS strand, which stimulate the activity of mAP to different extent (c). T18A* (Sample #7) denotes 1:5-diluted T18A variant of mOS.
