Properties of the alpha-helix. 1  The structure repeats itself every 5.4 Angstroms along the helix axis, ie we say that the alpha-helix has a pitch of 5.4 Angstroms. Alpha-helices have 3.6 amino acid residues per turn, ie a helix 36 amino acids long would form 10 turns.
221 Mathematical Properties of DNA Structure. The total length of the DNA (s), the number of end loops (n) and predicts several geometric and mechanical properties such as: the super-helix angle (ss), Ã standoff (distance) d in the balanced, ply and the tension in the (Strand). t
