Fig. 3. — Dependence of the N^∗ helix wave vector q on nDNA concentration c and corresponding interaxial distance d_H (upper x axis). Open blue dots: allCG2 behavior. Handedness inversion occurs at c_INV ∼650 mg/mL (vertical dashed line), corresponding to d_H ∼3.2 nm between neighboring helices. Pictures show typical textures of N^∗ phase, LH at low c and RH at high c, and nematic phase at intermediate c. Pictures side ∼80 μm. Red and green dots: average helical period vs. transition concentration c_IN for each of the sequences. Red dots: LH sequences. Green dots: RH sequences. Black dot: achiral AAC sequence. Open red dot: long DNA.
