Fig. 3. Dependence of dynamics on repeat length.

Fig. 3

Transition density plots from TIRF time traces of 3WJs with three complementary CAG (orange) and CTG (blue) repeats in the duplex and (CAG)n slip-outs (n = 4, 6, 8, 10, 20, and 30). 3WJs with slip-outs of (CAG)4 have two FRET states, while all other 3WJs are fitted to six FRET states. Similar plots are found for 3WJs with (CTG)n slip-outs (Supplementary Fig. 20). Measured at 20 °C in a buffer containing 1 mM MgCl2.
