==Overview==
+
The structure formed by the DNA sequence d(GCGGTGGAT) in a 100 mM Na(+) solution has been determined using molecular dynamics calculations constrained by distance and dihedral restraints derived from NMR experiments performed at isotopic natural abundance. The sequence folds into a dimer of dimers. Each symmetry-related half contains two parallel stranded G:G:G:G tetrads flanked by an A:A mismatch and by four-stranded G:C:G:C tetrads. Each of the two juxtaposed G:C:G:C tetrads is composed of alternating antiparallel strands from the two halves of the dimer. For each single strand, a thymine intersperses a double chain reversal connecting the juxtaposed G:G:G:G tetrads. This architecture has potential implications in genetic recombination. It suggests a pathway for oligomerization involving association of quadruplex entities through GpC steps.
