摘要
The duration of S phase in early embryos is often short, and then increases as development proceeds because of the appearance of late-replicating regions of the genome. In the April 1, 2012, issue of Genes & Development, Farrell and colleagues (pp. 714-725) demonstrate that the down-regulation of cyclin-dependent kinase 1 (Cdk1) activity triggers the onset of late-replicating DNA and an increase in S-phase length in Drosophila embryos, revealing an unexpected role for Cdk1 in replication control during development.
