Hybridization experiments with suppression resulted in labeling of all the autosomal and X chromosomes
constitutive heterochromatin of each species (Figure 4).
Mutability of
constitutive heterochromatin (C-bands) during eukaryotic chromosomal evolution and their cytological meaning.
Constitutive heterochromatin regions are found at or around centromeres and telomeres using the C-banding method.
The distribution of
constitutive heterochromatin (C-banding) in this specimen showed pericentromeric bands in all autosomes.
The analysis of the C-banding pattern revealed large blocks of
constitutive heterochromatin located on the pericentromeric regions of all chromosomes (Figure 2), and the first pair presented a completely heterochromatic long arm.
Constitutive heterochromatin regions (C-bands) were revealed using the method of Summer (1972), using propidium iodide as a counterstain.
C banding by
constitutive heterochromatin was located in pericentromeric and telomeric position.
Morphological variations of
constitutive heterochromatin are frequently detected during routine cytogenetic analysis.
The latest research for examining
constitutive heterochromatin, pathology-related inclusions and sumoylation are also discussed.
Constitutive heterochromatin blocks were located at centromeric and telomeric regions of practically all chromosomes, some being more conspicuous than others.
Constitutive heterochromatin was located only at telomeric regions in tetraploid B.
