These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation. Chromatin remodeling is an epigenetic phenomenon.

- Chromatography, gas (GC)
Chromatography, gas (GC): A type of automated chromatography (a technique used to separate mixtures of substances) in which the mixture to be analyzed is vaporized and carried by an inert gas through a special column and thence to a detection device. The special column can contain an inert porous solid (in gas-solid chromatography) or a […]

Chromesthesia: A type of synesthesia in which which a nonvisual stimulus causes the individual to perceive color. Color hearing is a form of chromesthesia. In color hearing a musical tone elicits a color. One well-studied case involved an art teacher who had a range of consistent linkages between tone and color. For her, high octaves […]
