| In Drosophila, relocation of a euchromatic gene near centromeric or telomeric heterochromatin often leads to its mosaic silencing. |
| Both retrovirus-like organization and expression are typical of the functional gypsy proviruses that have inserted recently into the euchromatic DNA of some strains. |
| In situ hybridization to polytene chromosomes confirmed that each insertion was in a typical euchromatic, banded region. |
| Numerous genes act to remodel and repress chromatin in heterochromatin and around euchromatic genes during development. |
