Dependencies of −logKI on the length of inhibitor (n) for ss and ds deoxyribooligonucleotides (a) and ribooligonucleotides (b). (a) d(pT)n (crosses), d(pA)n (filled squares), d(pC)n (open circles), d(pG)n (triangles), d[(pF)npT] (open squares), d(pT)n·d(pA)n (filled circles). (b) (pU)n (crosses), (pC)n (open circles), (pA)n (filled squares), (pU)n·(pA)n (closed circles); the curves for d(pA)n (crosses) and d(pT)n·d(pA)n (diamonds) are given for comparison.
