| Chromosome staining/banding/FISH | Five active Ag-NORs were identified on terminal position of short arms or sub-centromere regions of metacentric and submetacentric chromosomes. Constitutive heterochromatin was observed in centromeric and/or pericentromeric region of most chromosomes. Six 18S rDNA positive signals (both active and non-active) were identified to metacentric and submetacentric chromosomes. Two 5S rDNA sites located on arms of a medium-sized acrocentric chromosome pair. Telomeric repeats of (TTAGGG)n showed the typically telomeric signals on both telomeres and/or centromeric region of all chromosomes. |
