Definition of Dicentric chromosome
Dicentric chromosome: A chromosome that is abnormal in that it has two centromeres rather than one. Because the centromere is essential for chromosome division, a dicentric chromosome is pulled in opposite directions when the cell divides. This causes the chromosome to form a bridge and then break and be unstable.Source: MedTerms™ Medical Dictionary
