Banding of chromosomes: The treatment of chromosomes to reveal characteristic patterns of horizontal bands like bar codes.
The banding patterns lend each chromosome a distinctive appearance so the 22 pairs of human nonsex chromosomes and the X and Y chromosomes can be identified and distinguished without ambiguity. Banding also permits the recognition of chromosome deletions (lost segments), chromosome duplications (surplus segments) and other types of structural rearrangements of chromosomes.
Banding Patterns. Chromosomes in metaphase can be identified using certain staining techniques, so called banding. Cells are cultured and then stopped in metaphase to ...
A chromosome banding pattern is comprised of alternating light and dark stripes, or bands, that appear along its length after being stained with a dye.
Chromosomes display a banded pattern when treated with some stains. Bands are alternating light and dark stripes that appear along the lengths of chromosomes.
C-banding stains centromeres. R-banding is the reverse of C-banding and stains non-centromeric regions in preference to centromeres (left upper image from rev).
In cytogenetics, the study of chromosomes and their abnormalities, every chromosomal pair has a G-band pattern that is unique. This allows scientists to recognize ...
