微核是由染色单体或染色体的无着丝点断片或因纺缍体受损伤而失去的整个染色体,于细胞分裂后期仍留在细胞质中,在子代细胞中形成的一个或几个规则的圆形或椭圆形小体。微核试验(Micronucleus Test,简称MNT)是通过检测微核率的变化来筛选染色
Micronuclei are chromosomal or chromosomal non-filamentous fragments or spinosum damaged by the loss of the entire chromosome in the late cell division remain in the cytoplasm of the progeny cells in the formation of one or several rules Round or oval body. Micronucleus test (Micronucleus Test, referred to as MNT) is to detect changes in micronucleus rate to screen for staining
