Abstract

A. Sathvik Raj

Cytogenetics is the branch of genetics that correlates the structure, number, and behaviour of chromosomes with heredity and diseases. Giemsa has become the most commonly used stain in cytogenetic analysis. Most G-banding techniques require pretreating the chromosomes with a proteolytic enzyme such as trypsin. Gbanding preferentially stains the regions of DNA that are rich in adenine and thymine. The study of chromosomes, which are long strands of DNA and protein that contain most of the genetic information in a cell .
