The statistical correlation of nucleotides in protein-coding DNA sequences.
The statistical correlation of nucleotides in a DNA sequence is described by a set of redundancies D1, D2, D3, . . . . By calculation of [Dn] of 2341 coding regions of nucleic acid sequences it is demonstrated that about 2/3 of sequences has correlation length less than or equal to 2, 10% of sequences--correlation with 3-periodicity and others--long range aperiodic correlations. The implications of the results from the interactions of random mutation and natural selection are discussed briefly.
