Comparative studies on parallel and antiparallel duplex and triplex DNA.


Parallel strand models for base sequences d(A)10.d(T)10,d(AT)5.d(TA)5, d(G5C5).d(C5G5), d(GC)5.d(CG)5 and d(CTATAGGGAT).d(GATATCCCTA), where reverse Watson-Crick A-T pairing with two H-bonds and reverse Watson-Crick G-C pairing with one H-bond or with two H-bonds were adopted, and three models of d(T)14.d(A)14.d(T)14 triple helix with different strand… (More)
