Abstract:
This paper puts forward the numerical signal sequence correlated with the nucleotide sequence and the discrete Fourier analysis approach of its self-correlation and cross-correlation sequences. The approach is applied to the analysis of SARS virus nucleotide sequence. It proves that SARS virus nucleotide sequence has the periodicity laws one-third frequency and two-thirds frequency, which means that SARS virus has a strong coding ability and a high variability. Compared to SARS virus, AIDS virus has no the periodic law of two-thirds frequency, but the difference is unobservable by the approach mentioned in reference 1.
