[Periodicities in nucleotide distribution in the locus of the light chain of Gallus gallus immunoglobulins].

Fourier spectra of nucleotide sequences from chromosome 15 of Gallus gallus have been obtained. The periodical structures of several Ig locus fragments have been characterized. The uniqueness of Fourier spectra of the locus of the Ig light chain and its fragments (such as a variable region, a constant region, an enhancer, and several other fragments) among Fourier spectra of other fragments of chromosome 15 is demonstrated.

[The specificity in promoter recognition by the Bacillus subtilis RNA polymerase deltaA and deltaH holoenzymes is connected with periodicities in the promoter nucleotide sequences].

Promoters recognized by deltaA-RNA and deltaH-RNA polymerase have different periodic patterns their nucleotide disposition. By using the special method of Fourier analysis for symbolic sequences. Fourier spectra of the primary structure of promoters transcribed bv deltaA-RNA and deltaH-RNA polymerase were obtained.

[On some properties of spectral portraits of nucleotide sequences, computed my a matrix Fourier analysis method].

The quantitative characteristics of a spectral portrait of the nucleotide sequence of E. coli oriC were determined by the method of matrix Fourier analysis.

[Similarities in periodical structures in the position of nucleotides in regions of initiation of replication of bacterial genomes].

The regions of initiation of replication of some bacterial genomes were studied by the method of Fourier matrix analysis. A generalized spectral portrait of the primary structures of E. coli-like regions of initiation of replication in bacteria was obtained, which reflects the features of their structural and functional organization.
