Metaphase chromosomes of D. nasutoides were hybridized in situ with 3H-cRNA synthesized from the four satellites which make up 50--60% of the total DNA of this species. All four satellites were localized in the large, metacentric, heterochromatic chromosome four. They did not, however, appear to hybridize to centromeric or other constitutive heterochromatin, nor did they, with the exception of satellite I, seem to hybridize in the specific regions of chromosome four which, on the basis of C, Q, and H banding and AT contents, were predicted to contain some of these satellites.--Comparison of grain patterns with the results of fluorescent staining indicated that satellite-bearing heterochromatin was not always associated with other fractions of constitutive heterochromatin in interphase nuclei and was, at least partially, decondensed in some larger nuclei.
用从构成该物种总DNA 50 - 60%的四种卫星DNA合成的3H - cRNA，对纳氏果蝇的中期染色体进行原位杂交。所有四种卫星DNA都定位在大的、中着丝粒的、异染色质的第四条染色体上。然而，它们似乎并未与着丝粒或其他组成型异染色质杂交，除了卫星I外，它们似乎也未在第四条染色体的特定区域杂交，根据C、Q和H带型以及AT含量预测，这些区域应含有一些卫星DNA。——将银粒模式与荧光染色结果进行比较表明，携带卫星DNA的异染色质在间期核中并不总是与组成型异染色质的其他部分相关联，并且在一些较大的核中至少部分地发生了解聚。
