Cells respond to DNA damage or incompletely replicated chromosomes in G2 phase by delaying the G2/M transition so as to prevent attempts to segregate damaged chromosomes. DNA damage is detected by the kinases ATM and ATR, which activate Chk1, an inhibitory kinase of Cdc25. Chk1 inhibits Cdc25 activity both directly and by promoting its exclusion from the nucleus. The net effect is an increase in the threshold of cyclin B1 required to initiate the hysteretic transition to M-phas… WebJul 30, 2024 · Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two …
