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.
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.
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.
blocks were located at centromeric and telomeric regions of practically all chromosomes, some being more conspicuous than others.
was located only at telomeric regions in tetraploid B.
