Chromosome Band
Definition 1
Chromosomal bands observed after staining with specific dyes. The band pattern is the result of differential interactions between the dye and nonadjacent chromosomal regions. (NCI Thesaurus)
Definition 2
When chromosomes at a particular stage in cell division are stained using one of several laboratory techniques, a specific pattern of light and dark stripes (bands) appears when the chromosomes are viewed through a microscope; the banding pattern assists in assigning each chromosome its particular number and evaluating its structure. (NCI Dictionary)
