Chromosome banding pattern
WebThe chromosome banding patterns produced by certain DNA binding fluorescent dyes ( primary stain) can be enhanced or modified by an appropriately chosen DNA binding counterstain ( Fig. 1 ). The latter ligand is usually nonfluorescent or may be fluorescent, but not in the wavelength range of the primary stain (reviewed in 1,2). WebEach chromosome has a distinct banding pattern, and each band is numbered to help identify a particular region of a chromosome. This method of mapping a gene to a particular band of the chromosome is called cytogenetic mapping. For example, the hemoglobin beta gene ( HBB) is found on chromosome 11p15.4.

Comparisons of chromosome banding patterns can confirm evolutionary relationships between species and also reveal changes in karyotype that may have been important in speciation. The banding patterns of human, WebDrosophila polytene chromosomes are widely used as a model of eukaryotic interphase chromosomes. The most noticeable feature of polytene chromosome is transverse banding associated with alternation of dense stripes (dark or black bands) and light diffuse areas that encompass alternating less compact gray bands and interbands visible with …
WebA series of partial inversions of the heterochromatic C-band of chromosome 9 have been stained with distamycin A plus 4',6-diamidino-2-phenyl-indol-2HCl (DA/DAPI) and found to consist of three classes: (a) those in which only the C-band in the long arm fluoresces with DA/DAPI (these are the most frequent), (b) those in which only the C-band in the short …
