Una introducción a la predicción de la estructura secundaria del RNA mediante métodos estocásticos

Abstract

This article comments on an ongoing investigation, the prediction of RNA secondary structure using stochastic methods, in particular stochastic context-free grammars. While the investigation in this field has already made a lot of progress and is currently refining and improving its methods, this article is meant to provide an introduction to this subject for researchers in the digital signal processing area. After situating the problem in its biological context, we explain the basics of transformational grammars, which are used to model the RNA secondary structure. Then we present the three basic problems for these structures, and explain the three main algorithms to solve them, relating these to the analogous algorithms for hidden Markov models
