[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].

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.
