| The greater proximity of the centromere could cause suppression of recombination in the proximal euchromatin of fusion chromosomes. |
|
| This can be expected, since different chromosomes in a genome can have different organizations of genes, euchromatin, and heterochromatin. |
|
| The organization of DNA into euchromatin and heterochromatin is implicated in gene silencing. |
|
| Position-effect variegation results from the juxtaposition of euchromatin and heterochromatin by chromosome rearrangement or transposon insertion. |
|
| Unlike some types of transposons, MITEs do not appear to encode proteins, and most insertions of these elements occur in euchromatin, the form of chromosomal material that contains the majority of active genes. |
|
| Lesional cells showed elongated nuclei with dispersed euchromatin and marginated heterochromatin. |
