||The most important DNA sequence motifs that confer high affinity binding to the nucleosome are AA, TT, or TA dinucleotide steps (i.e., an A followed by another A, and so on), which recur every 10 bp, in phase with the DNA helical repeat (every 10.4 bp the DNA helix completes a turn), every time the DNA minor groove (phosphodiester backbone) rotates around to face inward toward the center of curvature of the nucleosomes protein core.
