Antheridial filaments showing the spermatocytes at the beginning of spermiogenesis (highlighted in the image), note that the nucleus is more condensed and heterochromatic
The nuclei were heterochromatic
with numerous small lipid droplets (Fig.
The C-banding of BST and BT was highly heterochromatic
and easily distinguished from A chromosomes (As) following the conventional C-banding methodology, whereas heterochromatin can be observed in a more condensed or dispersed state along both Bs and As.
NORs are located in the telomeric areas of the short heterochromatic
arms of two autosomal pairs (Arslan & Zima, in press).
Notably, we demonstrated that the heterochromatic
silent state of EYA4 gene contributed to t(8;21) AML leukemogenesis.
To safeguard genome integrity, these repetitive sequences are maintained in an epigenetically silent heterochromatic
state to prevent mutagenic recombination.
Non-telomeric sites as evidence of chromosomal rearrangement and repetitive (TTAGGG) arrays in heterochromatic
and euchromatic regions in four species of Akodon (Rodentia, Muridae).
Lepidopteran females display a heterochromatic
body in the interphase nuclei (reviewed in Traut & Marec 1996) also called sex chromatin body, which is derived from the W chromosome (Traut et al.
The supernumerary chromosome of the population from Itiz stream was completely heterochromatic
Li, Monochromatic and heterochromatic
subgraphs in edge-colored graphs - a survey, Graphs Combin.
These regions may also be found within chromosomal arms and sometimes the short arms of acrocentric chromosomes may be entirely heterochromatic
(Gaffaroglu and YA1/4ksel 2009).
In addition, DNA methylation is associated with heterochromatic
regions (Beisel and Paro 2011), and somatic mutation density in human cancer genomes have been found to be highest in heterochromatin-like domains (Schuster-Bockler and Lehner 2012).
