Micronuclei are commonly observed in cells undergoing replicative stress, such as those exposed to radiation or certain chemotherapeutic agents.
微核在受到辐射或某些化疗药物影响而处于复制压力的细胞中经常可见。
The frequency of micronuclei in a population of cells can serve as an indicator of genotoxicity.
细胞群体中的微核频率可以作为基因毒性的一个指标。
Researchers analyzed the micronucleus frequency in blood samples to assess the potential health effects of environmental pollutants.

In vitro studies often employ cytokinesis-blocking assays to examine the formation and stability of micronuclei.
体外研究常常使用阻滞有丝分裂的试验来考察微核的形成和稳定性。
Micronuclei are generated when chromosomes fail to properly segregate during mitosis, leading to their persistence in daughter cells.
当染色体在有丝分裂过程中未能正常分离时，就会产生微核，并在子代细胞中持续存在。
A high prevalence of micronuclei in a cell population may indicate a higher risk of cancer development.
细胞群体中微核的高发生率可能预示着癌症风险增加。
Scientists compare micronucleus frequencies between different groups to identify possible sources of genotoxic exposure.
