    "abstract": "We enumerate the number of RNA contact structures according to their genus,\ni.e. the topological character of their pseudoknots. By using a recently\nproposed matrix model formulation for the RNA folding problem, we obtain exact\nresults for the simple case of an RNA molecule with an infinitely flexible\nbackbone, in which any arbitrary pair of bases is allowed. We analyze the\ndistribution of the genus of pseudoknots as a function of the total number of\nnucleotides along the phosphate-sugar backbone.",
