C-banding stain (medicine) and regulator gene (medicine)


C-banding stain (medicine)


C-banding stain
<technique> A selective chromosome banding stain used in human cytogenetics, employing Giemsa stain after most of the DNA is denatured or extracted by treatment with alkali, acid, salt, or heat; only heterochromatic regions close to the centromeres and rich in satellite DNA stain, with the exception of the Y chromosome whose long arm usually stains throughout.

Synonym: centromere banding stain.


regulator gene (medicine)


regulator gene


A gene that produces a repressor substance that inhibits an operator gene when combined with it. It thus prevents production of a specific enzyme. When the enzyme is again in demand, a specific regulatory metabolite inhibits the repressor substance.
