Cyclin degradation: don't mes(s) with meiosis.
Cyclin degradation is required for exit from mitosis and enables a new round of DNA replication in the subsequent S phase. A recent study in fission yeast shows that, during exit from meiosis I, the Mes1 protein partially inhibits cyclin degradation and thereby allows entry into meiosis II without an intervening S phase.
