Dark bands on chromosomes
WebA common staining procedure involves dye Giemsa, which produces a unique pattern of light and dark bands ( G banding ) on each chromosome. Dark bands on the chromosomes represent areas of the DNA that are tightly compacted (heterochromatin); light bands represent areas of the DNA that are not as tightly compacted (euchromatin). WebAug 1, 2024 · Giemsa staining is a staining method to stain particularly malaria and other parasital diseases. G-bands occur because Giemsa stain consists of A,T rich material i.e. poor gene such that dark and white bands occur. Each chromosome has an unique reaction to Giemsa staining so G-bands occur. 0 points.
