Detection of Kinase and Phosphatase Activities

The eukaryotic cell cycle is a process in which cells grow and then divide into two genetically identical cells. The cell cycle is divided into four discrete phases allowing for the orderly transition from deoxyribonucleic acid (DNA) replication to chromosomal condensation, spindle formation, and cytokinesis. These phases are G1, in which a cell prepares for DNA replication; S, in which DNA synthesis takes place; G2, in which the cell ensures its genetic information has been faithfully replicated; and M, in which the homologous chromosomes are separated and cell division takes place.
