Мы искали среди контекстных и конформационных характеристик ДНК детерминирующие факторы, которые способствуют этой упаковке. Мы разработали статистику, основанную на величине изгиба ДНК, для определения характера предпочтения позиционирования нуклеосом в тандемных повторах. Было выявлено статистически значимое отличие профиля изгиба в тандемных повторах от случайной модели. Используя преобразование Фурье, мы выяснили, что не менее 50 % мономеров имеют периодичность профиля изгиба ДНК в районе 170 п.н., что соответствует длине ДНК, обернутой вокруг нуклеосомы, при рассмотрении двух первых гармоник в профиле изгиба ДНК. Мы определили, что в растениях схема позиционирования нуклеосом в субтеломерных сателлитах значимо отличается от аналогичной схемы в центромерных сателлитах.</p></abstract><trans-abstract xml:lang="en"><p>Satellite DNA, consisting of tandem repeats, forms heterochromatic regions packed into nucleosomes. Sequence and conformational DNA features responsible for the high efficiency of this package have been sought with a Fourier transform. The curvature profiles in tandem repeats differ significantly from a random model. As many as 50 % of the monomers have a periodicity of DNA bends in the vicinity of 170 bp, fitting the wrapping length of a single nucleosome within two highest-order harmonics in the DNA curvature profile. The nucleosome positioning scheme in subtelomeric satellites in plants differs from that in centromeric satellites.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нуклеосома</kwd><kwd>позиционирование</kwd><kwd>Фурье преобразование</kwd><kwd>изгиб ДНК</kwd><kwd>тандемные повторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nucleosome</kwd><kwd>positioning</kwd><kwd>Fourier transform</kwd><kwd>satellite repeats</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>В.Г.Левицкий, А.В.Вершиин; Госконтракт; суперкомпьютерный центр ИВМиМГ СО РАН (www.sscc.ru)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Deal R.B., Henikoff J.G.
