It is known that there are several codes residing simultaneously on the DNA double helix. The two best-characterized codes are the genetic code--the code for protein production, and the code for DNA packaging into nucleosomes. Since these codes have to coexist simultaneously on the same DNA region, both must be degenerate to allow this coexistence. A-tracts… (More)
Extensive DNA sequence analysis of three eukaryotes, S. cerevisiae, C. elegans, and D. melanogaster, reveals two different AA/TT periodical patterns associated with the nucleosome positioning. The first pattern is the counter-phase oscillation of AA and TT dinucleotides, which has been frequently considered as the nucleosome DNA pattern. This represents the… (More)
Positional correlation analysis for the complete genome of Saccharomyces cerevisiae is performed with the aim to reveal possible chromatin-related sequence features. A strong periodicity with the period 10.4 bases is detected in the distance histograms for the dinucleotides AA and TT, with the characteristic decay distance of approximately 50 base pairs.… (More)
Prokaryotic sequences are responsible for more than just protein coding. There are two 10- to 11-base periodical patterns superimposed on the protein coding message within the same sequence. Positional auto- and cross-correlation analysis of the sequences shows that these two patterns are a short-range counter-phase oscillation of AA and TT dinucleotides… (More)
The concept of madness and the types of behaviour so labelled are discussed in the context of traditional judaic sources, such as the Talmud.
