The principles of three dimensional organization of primary and secondary orders polytene chromosomes in ovarian nurse cells of Drosophila melanogaster were elucidated. Contrary to somatic tissues, no joining of chromosome arms into local chromocentre was discovered. The chromosomes are separated in the nuclear space and are attached to the nuclear envelope by the centromeric (and the XL arm--by the telomeric) sites, the arms of autosomes (especially primary polytene chromosomes) being separated in the area of attachment. Polytenized XR arm of the X chromosomes were discovered. The architecture of chromosomes discovered in ovarian nurse cells is tissue-specific and differs considerably from the organization of polytene chromosomes of somatic tissues.
阐明了黑腹果蝇卵巢滋养细胞中一级和二级多线染色体的三维组织原则。与体细胞组织不同，未发现染色体臂连接形成局部染色中心。染色体在核空间中分离，并通过着丝粒位点（X染色体的XL臂通过端粒位点）附着于核膜，常染色体的臂（尤其是初级多线染色体）在附着区域分离。发现了X染色体的多线化XR臂。在卵巢滋养细胞中发现的染色体结构具有组织特异性，与体细胞组织的多线染色体组织有很大差异。
