chromatin

Example:Euchromatin is more accessible to transcription factors for gene expression.

Definition:The condensed, lightly stained, and active-in-transcription chromatin of the interphase cell that is distinguishable from the heterochromatin, which is dense, not transcriptionally active, and more highly condensed.

Example:Heterochromatin is less accessible to transcription factors and serves more regulatory functions.

Definition:The dense, stainable chromatin of the interphase cell, physically more condensed and less transcriptionally active than euchromatin, usually located adjacent to the centromeres and near the nuclear membrane.

Example:During cell division, chromatin undergoes condensation into chromosomes.

Definition:The process of becoming more compact or denser as a result of the contraction of its parts.
