Micronucleus - Wikipedia
WebA micronucleus is a small nucleus that forms whenever a chromosome or a fragment of a chromosome is not incorporated into one of the daughter nuclei during cell division. It usually is a sign of genotoxic events and chromosomal instability.

WebMicronuclei are small membrane bounded compartments with a DNA content encapsulated by a nuclear envelope and spatially separated from the primary nucleus. Micronuclei have long been linked to chromosome instability, genome rearrangements, and mutagenesis. They are frequently found in cancers, during senescence, and following genotoxic stress.

WebMicronucleus (MN) is the extranuclear bodies of the damaged part of chromosome usually used to assess toxic potential of genotoxic agents. The study of DNA damage at the chromosome level is an essential part of genotoxicity testing because chromosomal mutation is an important event in carcinogenesis.
