Mitosis: Chromosomal Rearrangements

Chromosomal rearrangements occur during mitosis as a result of chromosomal breakage and rejoining. Such chromosomal rearrangement occurs more frequently in cancer cells than during embryogenesis or postnatally, usually as a result of environmental exposures and/or mutations resulting in DNA repair defects.

Keywords: chromosomal instability; breakage–fusion–bridge cycle; gene amplification; chromosomal rearrangement; cancer
