Figure 5.
Free energy penalty for focus mismatch (m = A, x = 10) derived from experimental intensities according to Equation (8) as a function of the location x + Δx of the second mismatch (n, x + Δx). For each |Δx > 4| the three values, one per possible mismatch, are indicated by the letter representing the mismatching nucleotide n of the probe. The target sequence is written in top of the x-axis in 3′ – 5′ notation, t1 in left pane, t2 in right pane. The dotted line corresponds to the median value of the 48 estimates. The circled point is the estimate without second mismatch coming from Equation (4). For this particular mismatch, the free energy penalty for both t1 and t2 is identical and corresponds to
