Tandem Repeats Localization Using Spectral Techniques

The detection of tandem repeats is important in biology and medicine as it can be used for phylogenic studies and disease diagnosis. A major difficulty in identification of repeats arises from the fact that the repeat units can be either exact or imperfect, in tandem or dispersed, and of unspecified length. This paper presents results obtained with a modified product spectrum and BW spectrograms to isolate position and length of tandem repeats (TRs) in DNA sequences.
