Abstract
Investigations of heterochiral oligodeoxynucleotides 50-TD1GD2GD3- 30-30-GL3GL2TL1-50 (L33) and 30-TD1GD2GD3-50-50-GL3GL2TL1-30 (L55) forming quadruplex structures are reported. Data indicate the presence of enantiomeric left- and right-handed quadruplex helices. In the case of L55, NMR experiments point to an unusual equilibrium between them.File | Dimensione | Formato | |
