Prediction of protein coding regions by combining Fourier and Wavelet Transform

Identifying protein coding regions in DNA sequences is an important step in the location of genes. The major signal in protein coding regions for most of genomic sequences is three-base periodicity. This paper proposed a Fourier-Wavelet-based method to predict protein coding regions based on the previous Fourier-based predictor. The validity of this approach is verified by a great deal of research results from theoretical analysis and experiments. Sensitivity´s increase and specificity´s decrease demonstrate the efficacy of the proposed predictor.
