Regulation of cell division is essential for normal embryo development. The Cyclins and their Cyclin-dependent kinases are key regulators controlling this process. In this thesis, I examine the role of cyclin B1 and cyclin B2 in zebrafish development. It is thought that both Cyclins are necessary for a cell to progress past the G2/M checkpoint into mitosis. First, I show that zygotic Cyclin B1 is essential for normal cell cycle progression, but not for cells to enter mitosis. Lack of zygotic Cyclin B1 in the early arrest mutant specter, which carries a nonsense mutation in the cyclin B1 gene, …
