G bands produced with Giemsa stains are useful markers for identifying specific chromosomes. The chromosomes are subjected to brief proteolytic treatment and then stained with Giemsa reagent, producing distinctive bands at characteristic places. (a) Scanning electron micrographs of chromosomes X, 4, and 5 show constrictions at the sites where bands appear in light micrographs (insets). (b) Standard diagrams of G bands (purple). Regions of variable length (green) are most common in the centromere region (e.g., on chromosome 4). By convention, p denotes the short arm; q, the long arm. Each arm is divided into major sections (1, 2, etc.) and subsections. The short arm of chromosome 4, for example, has five subsections. DNA located in the fourth subsection would be said to be in pi4. [Part (a) from C. J. Harrison et al., 1981, Exp. Cell Res. 134:141; courtesy of C. J. Harrison.]
