Figure 1
The analyzed DNA fragment, a dinucleotide without its 5′ phosphate, is drawn in black and is referred to as a step. Its structure is represented by the nine torsion angles δ, ∊, ζ, α1, β1, γ1, δ1, χ and χ1; the atoms defining the torsions are labelled. dTG is shown here; all 16 possible dinucleotide sequences were included in the study. |
