Identifying the Coding and Non Coding Regions of DNA Using Spectral Analysis
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 2
Abstract
This paper presents a new method for exon detection in DNA sequences based on multi-scale parametric spectral analysis Identification and analysis of hidden features of coding and non-coding regions of DNA sequence is a challenging problem in the area of genomics. The objective of this paper is to estimate and compare spectral content of coding and non-coding segments of DNA sequence both by Parametric and Non-parametric methods. In this context protein coding region (exon) identification in the DNA sequence has been attaining a great interest in few decades. These coding regions can be identified by exploiting the period-3 property present in it. The discrete Fourier transform has been commonly used as a spectral estimation technique to extract the period-3 patterns present in DNA sequence. Consequently an attempt has been made so that some hidden internal properties of the DNA sequence can be brought into light in order to identify coding regions from non-coding ones. In this approach the DNA sequence from various Homo Sapiens genes have been identified for sample test and assigned numerical values based on weak-strong hydrogen bonding (WSHB) before application of digital signal analysis techniques.
