Study of the organization of polytene chromosomes in the nuclei of Drosophila melanogaster pseudonurse cells with the use of the DNA library of the Drosophila orena chromocenter

Study of the organization of polytene chromosomes in the nuclei of Drosophila melanogaster... The location of the Drosophila orena chromocenter in polytene chromosomes of pseudonurse cells of the D. melanogaster ovaries (the otu11 mutation) and salivary glands has been studied. Numerous sites of location of the D. orena chromocenter DNA have been found throughout the length of D. melanogaster chromosomes. The specific distribution of the binding sites for the DNA probe has made it possible to identify chromosomes and analyze their mutual positions in the three-dimensional space of the nuclei of pseudonurse cells. The mutual positions of chromosomes have been found to vary, the pericentromeric regions of different chromosomes differing from one another in associative ratios. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The location of the Drosophila orena chromocenter in polytene chromosomes of pseudonurse cells of the D. melanogaster ovaries (the otu11 mutation) and salivary glands has been studied. Numerous sites of location of the D. orena chromocenter DNA have been found throughout the length of D. melanogaster chromosomes. The specific distribution of the binding sites for the DNA probe has made it possible to identify chromosomes and analyze their mutual positions in the three-dimensional space of the nuclei of pseudonurse cells. The mutual positions of chromosomes have been found to vary, the pericentromeric regions of different chromosomes differing from one another in associative ratios.
