微核是细胞有丝分裂后期仍滞留在细胞质中的染色体断片或染色单体。随着微核形成机理和意义的阐明以及检测手段和实验技术的不断改进和完善，目前微核试验已被公认为筛选致突变物的主要方法之一，在预测致癌危险性、检测非整倍体诱发剂及其它遗传危害方面也得到广泛应用。与体
Micronuclei are chromosomal fragments or chromatids that remain in the cytoplasm at the late mitotic stage of the cell. With the elucidation of the mechanism and significance of micronucleus formation and the continuous improvement and improvement of detection methods and experimental techniques, the current micronucleus test has been recognized as one of the main methods for screening mutagens. In predicting the carcinogenic risk and detecting aneuploidy Body-induced agents and other genetic hazards have also been widely used. And body
