Abstract:
In this paper we apply a few computational and visual tools, specific to digital signal processing, to the analysis of biomolecular sequences. In particular, we prove that color spectrograms can help in visually identifying protein coding areas of the DNA strand and provide, in the form of local "texture", significant information about biomolecular sequences, thus facilitating the understanding of local nature, structure and function. We also show that the magnitude of a properly defined function in the spectral domain can be a predictor for the existence of protein coding regions in DNA sequences.
