Question

what are G bands ?

Answer 1

G bands are specific regions on the chromosomes that can be observed when the chromosomes are stained and viewed under a microscope. These bands are created through a process called Giemsa staining, which results in the unique pattern of light and dark bands on the chromosomes. G bands are used to help identify and study the chromosome structure and to detect changes such as deletions, duplications, and translocations that may be associated with genetic disorders.
