Quizplus · Accepted Answer

The letters used to describe bands on chromosomes refer to the staining procedure that was used to reveal them. G-banding indicates the use of Giemsa staining, Q-banding indicates quinacrine staining, R-banding indicates relative staining, and C-banding indicates centromeric staining. These stains produce different patterns on the chromosomes, allowing them to be distinguished and studied under a microscope. The letters do not refer to the position, size, gene content, or relative importance of the bands.
