Abstract. We study the effect of the composition of the genetic sequence on the melting temperature of
double stranded DNA, using some simple analytically solvable models proposed in the framework of the
wetting problem. We review previous work on disordered versions of these models and solve them when
there were not preexistent solutions. We check the solutions with Monte Carlo simulations and transfer
matrix numerical calculations. We present numerical evidence that suggests that the logarithmic corrections
