A Gene Prediction Method Based on Statistics and Signal Processing
  Bioinformatics, as an emerging and rapidly developing interdisciplinary, has become a promising and popular research field in 21st century. Extracting and explaining useful biological information from huge amount of genetic data is an urgent issue in post-genome era. In eukaryotic DNA sequences, gene consists of exons and introns. To predict the location of exons which carry most genetic information accurately has become one of the most essential issues in bioinformatics. Here, we have used biological characteristics of introns to find the candidate initial and final exon sections. Then we select candidate exon sections by using Support Vector Machine (SVM). Next, we predict exon sections accurately based on Discrete Fourier Transform (DFT) and using three-base periodicity of DNA sequence signals. This paper provides a gene prediction method based on statistics and signal processing and also, the improvement and prospect for this method in the future are discussed.
