What is M banding?- Requirement, Process, Protocol and Applications

Chromosome banding / By drtusharchauhan

M-Bands or M Banding is a high-resolution chromosome banding technique that finds cryptic chromosomal rearrangements such as inversion, translocation, deletion or duplication at the chromosome level. Banding techniques have a significant role in cytogenetics especially in karyotyping. The whole cytogenetic studies are conducted around chromosomes and to encounter chromosomal anomalies. Many techniques and improvements over …

“The C banding or C bands is a technique utilized in karyotyping which stains especially the centromeric region, stronger than other regions.” Do you know? The centromere region of chromosomes is a repetitive DNA region, condensed and the non-active region. It distinguished two arms from each other. Centromere helps in the separation of chromosomes or …
