facultative heterochromatin the chromatin in regions of the chromosomes that become heterochromatic in certain cells and tissues; for example, it makes up the inactive X chromosome in female somatic cells. (het'Är-Å-krÅ'mÄ-tin),
In biology, histones are highly alkaline proteins found in eukaryotic cell nuclei that package and order the DNA into structural units called nucleosomes. They are the chief protein components of chromatin, acting as spools around which DNA winds, and playing a role in gene regulation. Without histones, the unwound DNA in chromosomes would be very long. For example, each human diploid cell has about 1.8 meters of DNA; wound on the histones, the dipliod cell has about 90 micrometers of chromatin.
