  • "These modifications cause parts of chromosomes to condense into so-called heterochromatin, burying the regulatory regions of p53 target genes deep within," says graduate student and co-first author Fanny E. Estermann.

  • In general, C-bands and G-bands are complexed with proteins and RNAs to give a more compact organization called heterochromatin, whereas R-bands have a more open conformation referred to as euchromatin.

  • In contrast, a major part of the, non-active 'more compacted DNA regions, termed heterochromatin, are located in the nuclear periphery.

  • ~ Exploring the Dark Matter of the Genome -- "Not so long ago, the difficult-to-sequence, highly repetitive, gene-poor DNA found in regions of chromosomes known as heterochromatin was called "junk."

  • In non-dividing cells, DNA is associated with proteins to form the so-called chromatin, with more condensed "heterochromatin" at the periphery and less condensed "euchromatin" in the interior.

    undefined

  • Certain regions are kind of stuffed away into something called heterochromatin, "

    Signs of the Times

  • "Most researchers thought heterochromatin had little or no function, because it appeared to lack the protein-coding genes that occur so richly in the chromosomes 'more accessible and better-studied euchromatin," says Karpen, a senior scientist in Berkeley Lab's Life Sciences Division and an adjunct professor of cell and molecular biology at the University of California at Berkeley.
