Mathematical descriptors of DNA sequences: development and applications
Over the last few years several authors have presented various methods to assign mathematical descriptors to DNA sequences in order to quantitatively compare the sequences and determine similarities and dissimilarities between them. The plethora of different methods used have made it necessary to compare them and determine which one(s), if any, best meet the needs required to characterize DNA s...
متن کاملData hiding methods based upon DNA sequences
In this paper, three data hiding methods are proposed, based upon properties of DNA sequences. It is highlighted that DNA sequences possess some interesting properties which can be utilized to hide data. These three methods are: the Insertion Method, the Complementary Pair Method and the Substitution Method. For each method, a reference DNA sequence S is selected and the secret messageM is inco...

15 صفحه اولAnalysis of DNA sequences using methods of statistical physics
We review the present status of the studies of DNA sequences using methods of statistical physics. We present evidence, based on systematic studies of the entire GenBank database, supporting the idea that the DNA sequence in genes containing noncoding regions is correlated, and that the correlation is remarkably long range, i.e., base pairs thousands of base pairs distant are correlated. We do ...
متن کاملComparative analysis of periodicity search methods in DNA sequences
To determine the periodicity of a DNA sequence, different spectral approaches are applied (discrete Fourier transform (DFT), autocorrelation (CORR), information decomposition (ID), hybrid method (HYB), concept of spectral envelope for spectral analysis (SE), normalized autocorrelation (CORR_N) and profile analysis (PA). In this work, we investigated the possibility of finding the true period le...
