G2-M arrest Mitosis follows DNA replication in the G2 phase of the cell-cycle after the mitotic Cdk, Cdk1(cdc2), is activated As diagramed in Fig

Wortmannin, an in- hibitor of ataxia telangiectasia–mutated and DNA-dependent protein kinase (DNA-PK), caused cell cycle arrest at G1 phase without inducing p53

Mam- malian cells also arrest in G2 in response either to DNA damage sustained during S phase, or incomplete DNA replication [23] A distinct G2 checkpoint may

We found that in four cdc mutants the cdc rad9 cells failed to arrest after a shift to the restrictive temperature, rather they continued cell division and died
