Abstract:
In order to obtain accurate and reliable gene identification information ,according to the given DNA sequences of numerical value mapping (based on Voss mapping and Z-curve mapping) ,DNA sequence power spectrum and the signal to noise ratio (SNR) are calculated by using fast Fourier transform (FFT ) and discrete wavelet transform algorithm .For the gene prediction of different types of living things ,the best threshold of gene prediction is deduced by bootstrap sampling algorithm ,and the properties of gene prediction method are assessed with specificity ,sensitivity and accuracy ,the model in gene recognition has fast operation ,high precision and good effects .
Keywords:gene identification  Fourier transform  wavelet transform  bootstrap sampling
