5-bromouracil induces transitions in both directions, A:T ↔ G:C Deamination of adenine results in A:T → G:C transitions and the deamination of cytosine produces G:C → A:T transitions, so nitrous acid induces transitions in both directions

Therefore, at fixed [S0], a plot of 1/v0 against [Io] (the Dixon plot) is linear. When [Io] = -Ki , it can be seen that 1/v0 = l!V max and is therefore independent of [S0], so Dixon plots for different values of [So] (but fixed [Eo]) intersect where [lo] = -Ki
