Micronucleus (MN) is a small round and DNA containing structure located in the cytoplasm outside of the main nucleus. The presence of MN is considered as a sign of chromosomal instability. MN contains a part of an entire chromosome that was incorrectly segregated during anaphase and fail to incorporate into the daughter's cell nuclei correctly. Replication stress, un-replicated DNA, mitotic spindle defects, DNA damage, and non-functional DNA damage checkpoints are contributing to MN formation. Since zygote is a fundament of a whole new organism, the presence of MN in this cell can cause embryonal mortality, infertility or serious congenital disorders.
