thumb|Figure comparing the effects of exposure to genotoxic agents (aneugens and clastogens) on DNA. Aneugens induce mis-segregation of chromosomes into daughter cells while clastogens break the DNA and chromosome. A clastogen is a mutagenic agent that disturbs normal DNA related processes or directly causes DNA strand breakages, thus causing the deletion, insertion, or rearrangement of entire chromosome sections. These processes are a form of mutagenesis which if left unrepaired, or improperly repaired, can lead to cancer. Known clastogens include acridine yellow, benzene, ethylene oxide, ars
