Chromosome, dicentric: An abnormal chromosome (a microscopically visible carrier of the genetic material DNA) with two centromeres rather than the normal one. The centromere is essential for the division of the chromosome. A dicentric chromosome is twice tethered and so is pulled in opposite directions when the cell divides and this causes the chromosome to form a bridge and then break. Dicentric chromosomes are a cause of chromosome instability.
Dicentric chromosomes result from the abnormal fusion of two chromosome pieces, each of which includes a centromere.
