Table 2.

The values of invariants of DNA persistence lengths and helical repeats obtained from elemental set 2 extended by fragments HPL2 and LPL2

Invariant combination of a^XY or γ^XY; symbol r corresponds to a or γ	Persistence length, a, nm	Helical repeat, γ, bp/turn
r^AA/TT	50.4 (50.3)	10.27 (10.26)
r^CC/GG	41.7 (40.5)	10.76 (10.73)
2/(1/r^AT + 1/r^TA)	42.7 (42.3)	10.62 (10.61)
2/(1/r^GC + 1/r^CG)	49.6 (50.3)	10.39 (10.36)
2/(1/r^AC/GT + 1/r^CA/TG)	50.7 (50.7)	10.59 (10.59)
2/(1/r^AG/CT + 1/r^GA/TC)	52.6 (53.2)	10.39 (10.40)
3/(1/r^AT + 1/r^GA/TC + 1/r^CA/TG)	46.7 (45.8)	10.51 (10.51)
3/(1/r^AC/GT + 1/r^CG + 1/r^GA/TC)	55.3 (57.4)	10.43 (10.42)

The values of the invariants obtained from elemental set 2 without the extension are shown in parenthesis.
