Roles of CDK and DDK in Genome Duplication and Maintenance: Meiotic Singularities.Cells reproduce using two types of divisions: mitosis, which generates two daughter cells each with the same genomic content as the mother cell, and meiosis, which reduces the number of chromosomes of the parent cell by half and gives rise to four gametes.  They require the activities of two types of serine-threonine kinases, the cyclin-dependent kinases (CDKs) and the Dbf4-dependent kinase (DDK).  CDK and DDK are essential for genome duplication and maintenance in both mitotic and meiotic divisions.
