Figure 2. The average probabilities of transition calculated as functions of negative superhelicity for a 5 kb plasmid containing a single denaturation-susceptible site and a single Z-susceptible site in an otherwise transition-resistant background.

The average probabilities are shown of Inline graphic either melting (solid) or forming Z-DNA (dotted), and of B-Z transition at Inline graphic (dashed) at temperature Inline graphic = 340 K.
