Abstract
Ribonucleic acid (RNA) lies at the heart of the central dogma. It spans the breadth of biological functions, from information storage to gene regulation and catalysis. RNA molecules must attain specific structures to perform these functions, and their structures depend on their sequences. Predicting the structure of RNA has been a central problem in computational biology. Various methods have been developed for this purpose - while some consider the thermodynamics of folding, others abstract away the details behind neural networks (NN). This paper presents a brief overview of the existing tools for predicting RNA secondary structures from a given single RNA sequence. Furthermore, a comparative analysis of the different prediction software packages is also presented. Performance is analyzed by running each of the available software packages on a novel dataset developed using 3D crystal structures of RNA. Software packages considered include those that can predict pseudoknots along with those that cannot. Variation in software performance based on the length and type of RNA is described.
