chromatin

 [kro´mah-tin]
the substance of the chromosomes, composed of DNA and basic proteins (histones), the material in the nucleus that stains with basic dyes.
sex chromatin the persistent mass of the material of the inactivated X chromosome in cells of normal females; called also Barr body.

chro·ma·tin

(krō'ma-tin),
The genetic material of the nucleus consisting of deoxyribonucleoprotein that occurs in two forms during the phase between mitotic divisions: as heterochromatin, seen as condensed, readily stainable clumps; as euchromatin, dispersed lightly staining or nonstaining material. During mitotic division the chromatin condenses into chromosomes.

(krō′mə-tĭn)
n.
A complex of nucleic acids and proteins, primarily histones, in the cell nucleus that stains readily with basic dyes and condenses to form chromosomes during cell division.

chromatin

The threadlike stainable material seen in nuclei during interphase, which corresponds to chromosomes (nucleic acids/DNA, associated histones, and other proteins bundled into nucleosomes) in the eukaryotic nucleus.

chromatin

Genetics The stainable material of interphase nuclei corresponding to chromosomes; chromatin consists of nucleic acids–DNA and associated histone protein, which are packed into nucleosomes; euchromatin is loosely packed and accessible to RNA polymerases. See Salt & pepper chromatin. Cf Heterochromatin.

chromatin

DNA. The elongated, fine-stranded complex of roughly equal quantities of DNA and the protein histone, from which chromosomes are made by condensing into a coil. The individual chromosomes cannot be distinguished in a chromatin strand.

chromatin

that part of the cell nucleus which becomes deeply stained with basic dyes. This is now known to be chromosomal material consisting of DNA together with HISTONE and nonhistone proteins.
