Рассмотрены исследования формирования и преодоления “нуклеосомного барьера” некоторыми видами РНК-полимераз. Показано, что для транскрипции хроматина сходные механизмы используются очень разными полимеразами. Приведены данные, свидетельствующие о сходстве механизмов транскрипционного и АТФ-зависимого ремоделирования хроматина. Предложена модель транскрипции через нуклеосому.</p></abstract><trans-abstract xml:lang="en"><p>The nucleosome forms the so-called “nucleosome barrier”, which presents a serious obstacle to the transcription machinery. We consider the study of formation and overcoming of the “nucleosomal barrier” by different RNA polymerases. It is shown that similar mechanisms are used by very different polymerases for transcription through chromatin. We discuss the data showing a high similarity between the mechanisms of transcription through chromatin and ATP-dependent chromatin remodeling. A model of transcription through the nucleosome is proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хроматин</kwd><kwd>транскрипция</kwd><kwd>нуклеосома</kwd><kwd>“нуклеосомный барьер”</kwd><kwd>ремоделирование хроматина</kwd><kwd>элонгация</kwd><kwd>РНК-полимераза 3.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chromatin</kwd><kwd>transcription</kwd><kwd>nucleosome</kwd><kwd>nucleosome barrier</kwd><kwd>chromatin remodeling</kwd><kwd>elongation</kwd><kwd>RNA polymerase III.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bednar J., Studitsky V.M., Grigoryev S.A., Felsenfeld G., Woodcock C.L.
