Meaning
The part of a cell nucleus that is relatively uncolored by stains or dyes.
Classification
Nouns denoting body parts.
Examples
- Achromatin has specific roles in regulating gene expression through its structural organization within the cell nucleus.
- Staining cells can help identify regions of euchromatin and achromatin based on the varying affinities of chromatin to stains.
- Chromatin regions that don't bind stain, or achromatin, are often less compact compared to chromatin that binds stain.
- The non-compact achromatin consists of larger, more distantly spaced nucleosomes.
- Euchromatin and achromatin often coexist within the same interphase nucleus, but their distinct structures remain.
