A measure of DNA periodicity

Abstract

A Fourier transform g(n) of a sequence of bases along a given stretch of DNA is defined. The transform is invariant to the labelling of the bases and can therefore be used as a measure of periodicity for segments of DNA with differing base content. It can also be conveniently used to search for base periodicities within large DNA data bases. © 1986 Academic Press Inc. (London) Ltd.
