Database of Periodic DNA Regions in Major Genomes

الملخص EN

Summary.

We analyzed several prokaryotic and eukaryotic genomes looking for the periodicity sequences availability and employing a new mathematical method.

The method envisaged using the random position weight matrices and dynamic programming.

Insertions and deletions were allowed inside periodicities, thus adding a novelty to the results we obtained.

A periodicity length, one of the key periodicity features, varied from 2 to 50 nt.

Totally over 60,000 periodicity sequences were found in 15 genomes including some chromosomes of the H.

sapiens (partial), C.

elegans, D.

melanogaster, and A.

thaliana genomes.
