Chromosome g banding
WebG-banding of chromosomes promises to be the most valuable technique for routine chromosome analysis due to its inherent simplicity, sensitivity, and stability of the material obtained. In the past, banding procedures have had several shortcomings in regard to efficiency and consistency of results. It is now possible to obtain good and consistent … WebThe ends of the chromosome are called telomeres. Each chromosome arm is divided into regions, or cytogenetic bands, that can be seen using a microscope and special stains. The cytogenetic bands are labeled p1, p2, p3, q1, q2, q3, etc., counting from the centromere out toward the telomeres.

WebAug 21, 2024 · Chromosome banding is an essential tool in Karyotyping. Karyotyping is a process of pairing and ordering all the chromosomes of the organism. The study is done to observe the abnormality of chromosomes. For chromosome staining, the cells are arrested at metaphase by using chemical like mytomycin C or colchisine. WebJul 28, 2024 · Unfortunately, G-banding has limited resolution, at the level of 5-10 megabases, which means that it cannot detect abnormalities smaller than this limit. G-banding results are readable only in a specific cell-cycle phase and depend on intact chromosomes with good morphology, so many stained cells are unusable.
