A, C, G, T refer to DNA bases, adenosine, cytosine, guanine, and thymine, respectively. For each sequence, we give the short name used in the text, the length N (base pair number), and the type of end-to-end aggregation (BE or SD). cIN is the critical concentration for the Isotropic-(Chiral) Nematic transition at room temperature and recalculated with an improved calibration of refractive index-concentration relationship). H is the observed handedness, LH, RH, or achiral nematic. The range of absolute values of the cholesteric pitch is determined within the concentration range of the N∗ phase at room temperature. The slope of the dependence of |p| on T (discussed in SI Text) and c is either positive (INC) or negative (DEC), and Handedness Inversion (HI) can occur. The last column highlights the sets of sequences described and discussed in the text. The missing quantities or dependencies have not been determined within this work.
