摘要

Accurate chromosome segregation is vital for organismal development and homeostasis, with errors in this process strongly associated with tumourigenesis. A network of safeguard clocks preserves mitotic fidelity by detecting and eliminating cells dividing outside the stereotyped duration of successful mitosis. This Perspective examines recent advances in our understanding of mitotic timing mechanisms, presents emerging evidence for novel mitotic clocks and proposes a conceptual framework for how cells integrate temporal cues to preserve genomic integrity.
