The majority of the studied interbands contained one gene with a single transcription initiation site; the remaining interbands contained one gene with several alternative promoters, two or more unidirectional genes, and “head-to-head” arranged genes. In addition, intricately arranged interbands containing three or more genes in both unidirectional and bidirectional orientation were found. Insulator proteins, ORC, <italic>P</italic>-insertions, DNase I hypersensitive sites, and other open chromatin structures were situated in the promoter region of the genes located in the interbands. This area is critical for the formation of the interband, an open chromatin region in which gene transcription and replication are combined.</p></abstract><trans-abstract xml:lang="ru"><p>Впервые изучили молекулярно-генетическую организацию междисков политенных хромосом, локализованных одновременно на молекулярной и цитологической картах генома Drosophila melanogaster. Большая часть изученных междисков содержала один ген, имеющий единственный старт транскрипции, остальные междиски – по одному гену с несколькими альтернативными промоторами, два и более однонаправленных гена и гены с расположением “голова-к-голове”. Также обнаружили сложноорганизованные междиски, в которых локализовались три и более гена, имеющие как однонаправленную, так и двунаправленную ориентацию. Инсуляторные белки, ORC, Р-инсерции, гиперчувствительные к ДНКазе I сайты и другие характеристики открытого хроматина располагались в промоторной области генов, находившихся в междисках. Эта область – критическая для образования междиска, участка открытого хроматина, в котором совмещаются процессы инициации транскрипции и репликации генов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Drosophila</kwd><kwd>organization of genome</kwd><kwd>polytene chromosomes</kwd><kwd>interbands</kwd><kwd>promoters</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дрозофила</kwd><kwd>организация генома</kwd><kwd>политенные хромосомы</kwd><kwd>междиски</kwd><kwd>промоторы</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантом Российского научного фонда № 14–14–00934.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kharchenko P.
