Figure 1.
Imino proton spectrum of the 22-nt human telomeric variant d[AGGG(CTAGGG)3] sequence (22CTA) in K+ solution with assignments for the major form listed over the spectrum. The imino protons are classified into three categories, corresponding to their involvement in G·G·G·G tetrad, G·C·G·C tetrad, or G·C base pair formation.
