The statement of the theorem

Define the standard B-DNA helix by its helical parameters (αB,βB,γB)(\alpha_B, \beta_B, \gamma_B), where α\alpha is the rise per base pair, β\beta is the twist angle, and γ\gamma is the roll angle. The Z-DNA conformation is characterized by a transition to a left-handed helix and a zigzag backbone structure. Mathematically, this transition is defined by the change in the helical parameters: \nαZ=αB/2\alpha_Z = \alpha_B / 2 \nβZ=−βB\beta_Z = -\beta_B \nγZ=π/2\gamma_Z = \pi/2 \nThis transformation results in a backbone vector r(n)\mathbf{r}(n) that follows a zigzag path, deviating from the sinusoidal path of B-DNA.
