Chromatids: The daughter strands of a duplicated chromosome joined together by a centromere.
Chromatin: The nucleoprotein material of chromosomes. Chromatin is essentially the substance of chromosomes. It is made up of DNA attached to a protein structure, together with chromosomal RNA. Chromatin exists in two states, euchromatin and heterochromatin, with different staining and functional properties.

- Chromatin remodeling
Chromatin remodeling: Dynamic structural changes to the chromatin occurring throughout the cell division cycle. 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 […]

They worry that they might mismanage money or that money might live up to its reputation as “the root of all evil.” Perhaps they remember well the ill fortune that befell the mythical King Midas. […]
