Predicting algorithm for RNA pseudoknotted structure

Pseudoknots are a frequent RNA structure. Based on the relative stability of the stems in RNA molecules, an algorithm is presented to predict RNA pseudoknotted structure,the introduced algorithm takes O(n
³
) time and O(n) space and outperforms other known algorithms in predicting accuracy. This algorithm not only reduces the time complexity to O(n
³
), but also widens the maximum length of the sequence The experimental results on the RNA sub-sequences in PseudoBase indicate that the algorithm has good accuracy, sensitivity and specificity.
