Figure 2.
1H 2D-water gated NOESY spectrum (mixing time 200 ms) of the DNA duplex containing the O:C mismatch collected at 22°C. Sequential NOE connectivities for a strand of d(GTGACOCACTG) are indicated by a solid line, and those for d(CAGTGCGTCAC) are indicated by a broken line. Intraresidue NOE connectivities between H1′ and H8/H6 are indicated by residue names.
