Wj. Lee et Lf. Luo, PERIODICITY OF BASE CORRELATION IN NUCLEOTIDE-SEQUENCE, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 56(1), 1997, pp. 848-851
The correlation spectrum of a symbolic sequence is defined. The harmon
ic heights in the spectrum of a nucleotide sequence are calculated rig
orously. A model of coding sequences is proposed and the origin of 3-p
eriodicity is explained. The possible occurrence of a hidden periodici
ty of base correlation with no peak in the spectrum is discussed.
