Cells that store epinephrine secretory vesicles. During times of stress, the nervous system signals the vesicles to secrete their hormonal content. Their name derives from their ability to stain a brownish color with chromic salts. Characteristically, they are located in the adrenal medulla and paraganglia (PARAGANGLIA, CHROMAFFIN) of the sympathetic nervous system
Either of the two longitudinally adjacent threads formed when a eukaryotic chromosome replicates prior to mitosis. The chromatids are held together at the centromere. Sister chromatids are derived from the same chromosome. (Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)

Chromatin Assembly and Disassembly -- See Also Histone Code
The specific patterns of changes made to HISTONES, that are involved in assembly, maintenance, and alteration of chromatin structural states (such as EUCHROMATIN and HETEROCHROMATIN). The changes are made by various HISTONE MODIFICATION PROCESSES that include ACETYLATION; METHYLATION; PHOSPHORYLATION; and UBIQUITINATION
