Abstract
The hidden periodicities in various genomes can be identified via
a Fourier transform of genomic DNA sequences. The typical search strategies
are described and the corresponding statistical criteria are presented.
The methods are applied to the structural analysis of genome for
bacteriophage PHIX174. The results indicate the importance role of
the coherent structural modifications along the several main periods
in the formation of the genome. Some possible mechanisms for the
features observed are discussed.
