Figure 1.

Oligonucleotides emulating long and short telomeric G-overhangs adopt distinct non-B DNA structures. CD spectra of oligonucleotide constructs emulating long (A) and short (B) telomeric G-overhangs (cf. Table 1). CD spectra were measured at RT in K⁺S buffer at a DNA concentration of 50 μm. The spectra were measured 24 h after sample annealing.
