Definition of euchromatin in English:

euchromatin

noun juːˈkrəʊmətɪnyo͞oˈkrōməˌtin

mass nounGenetics

Chromosome material which does not stain strongly except during cell division. It represents the major genes and is involved in transcription.
Compare with heterochromatin
Example sentencesExamples
- Position-effect variegation results from the juxtaposition of euchromatin and heterochromatin by chromosome rearrangement or transposon insertion.
- The wavy line represents euchromatin of chromosome 2.
- Further, in most organisms there is a virtual absence of exchange in heterochromatin and a reduction of exchange frequencies in euchromatin that lies near chromosomal elements such as centromeres and telomeres.
- This can be expected, since different chromosomes in a genome can have different organizations of genes, euchromatin, and heterochromatin.
- The greater proximity of the centromere could cause suppression of recombination in the proximal euchromatin of fusion chromosomes.

Derivatives

euchromatic

adjective ˌjuːkrəʊˈmatɪkˌjukrəˈmædɪk

Genetics

Relating to chromosome material which does not stain strongly except during cell division.
euchromatic genes
Example sentencesExamples
- This is due, in part, to the presence of large, complex blocks of duplicated genomic sequence at the boundary between centromeric satellite and unique euchromatic DNA.
- In Drosophila, relocation of a euchromatic gene near centromeric or telomeric heterochromatin often leads to its mosaic silencing.
- Numerous genes act to remodel and repress chromatin in heterochromatin and around euchromatic genes during development.
