Key Words Ageing; satellite association; fragile site.
Abstract Chromosomal study on satellite association and fragile site was made in ageing. Satellite association was studied on 68 cases and fragile site was studied on 91 cases from newborn to over 90 years by blood culture. Satellite association increased in ageing. The frequency of fragile sites was statistically high in only 20-30 years group, but no difference was found in newborn, 60-76 and over 90 years group.
