Revisiting the Genomics and Genetic Codes Using Walsh-Hadamard Spectrum Analysis

Abstract

Walsh-Hadamard spectrum is widely used in the field of science and technology like classification of cancer cells, image processing, speech processing, signal and image compression etc. In this paper, a genomic analysis using Walsh-Hadamard spectrum and cross-correlation has been done. Transformation of genetic code using Walsh-Hadamard spectrum has been given. We redefine the Walsh-Hadamard spectrum in genomics and analyse the origin of mRNA features by using this spectra. Finally, using Walsh-Hadamard spectrum the overall energy of the mRNA sequence has been evaluated.
