ABSTRACT

This paper presents a probabilistic approach to locate motifs in a given set of molecular sequences. Motif is a short sequence of DNA or RNA (or amino acids) which often consists of 5- 16 nucleotides. The methodology presented here is based on probabilistic approach (Likely Hood Ratio) with three wild card locations to express motif locations and their poor, moderate and good results on the basis of matches found is observed. The proposed method allows three displacement locations (i.e. 1, 9, & 11) unlike other motif finding techniques that allow only two displacement locations.
