Figure 10. Relative propensity of mutations occurring inside (A) and outside (B) of stem regions to base pair inside or outside the same region.

The statistics have been computed using a scanning window of size 50 with up to 8 mutations. When a mutation occurs in a stem region 10(A), we distinguish three cases: when the base pair is created inside the same stem region, when the base pair links another stem region and when the mutation base pairs outside any stem regions. In the case of a mutation happening outside the stem regions 10(B), we only need to distinguish whether the base pair links a stem region or not.
