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 .
