Abstract

The base-pairing of a nucleic acid secondary structure is a sort of biological palindrome. The base pairs of nucleic acid stems nest in a palindromic fashion with complementary base pairings rather than identical letters. In addition, nucleic acid stems are usually separated by a loop, i.e. a non palindromic sequence. At the moment, the problem of finding such a structure is solved through dynamic programming or in linear time with the use of the lowest common ancestor (S2_ScalabrinPolicriti0.png) preprocessing. We propose an algorithm which exploits matching statistics, is linear on the size of the input S2_ScalabrinPolicriti1.png, does not use S2_ScalabrinPolicriti0.png, builds the suffix tree only for S2_ScalabrinPolicriti1.png and saves a lot of memory.
