AN INVESTIGATION OF THE SINGLE STRAND DNA SYMMETRY BY FOURIER TRANSFORMATION METHOD

Summary

    A system of the single strand DNA symmetry based on the theory of coloured symmetry is proposed. The search of the fragments with the inversion symmetry is carried out by means of the Fourier transformation, DNA being preliminary presented as a three-dimen¬sional number series. For the search of the direct repeats the Fourier transformation is proposed as the first step to decrease the number of comparisons. The both methods have been tested on the model sequences as well as on the prokaryotic origins of replication.
