Figure 7.
The free energy penalty of tandem mismatches from experiment with target t1: , where x′ and y′ are complementary to x and y, respectively. ab denoted above the x-axis are the fixed nucleotides in the target. mn is a tandem mismatch in the probe and the vertical position of these letters in the plot give the associated free energy penalty. Note the low free energy penalty for
mismatches (encircled).
