The satellite DNAs of Drosophila virilis have been examined in diploid and polyploid tissues by isopycnic ultracentrifugation and thermal denaturation experiments. Previous work has established that the satellite DNAs are underreplicated in the polytene chromosomes of the salivary glands of D. virilis. The results of the present experiments demonstrate that this underreplication also takes place in the ovaries which contain nurse cells and follicle cells. These tissues are polyploid but do not show polytene chromosomes.
通过等密度超速离心和热变性实验，对果蝇（Drosophila virilis）二倍体和多倍体组织中的卫星DNA进行了检测。先前的研究已经证实，在果蝇唾液腺的多线染色体中，卫星DNA复制不足。本实验结果表明，这种复制不足也发生在含有滋养细胞和卵泡细胞的卵巢中。这些组织是多倍体，但没有显示出多线染色体。
