The study investigates the B to A transition of DNA in water-ethanol solutions using circular dichroism, revealing that the transition is reversible and occurs within a narrow range of ethanol concentrations. The presence of various ions affects the stability of the B form, and the transition is characterized as a cooperative process with a co-operativity length of 20 base pairs. The findings suggest that the B to A transition can be modeled using the Ising model, and the transition
