    7093   Mitotic Cell Cycle Checkpoint  A Cell Cycle Checkpoint That Ensures Accurate Chromosome Replication and Segregation by Preventing Progression Through a Mitotic Cell Cycle Until Conditions Are Suitable For the Cell to Proceed to the Next Stage. 
    51304   Chromosome Separation  The Cell Cycle Process in Which Paired Chromosomes Are Detached From Each Other. Chromosome Separation Begins with the Release of Cohesin Complexes From Chromosomes; in Budding Yeast This Includes the Cleavage of Cohesin Complexes Along the Chromosome Arms Followed by the Separation of the Centromeric Regions. Chromosome Separation Also Includes Formation of Chromatid Axes Mediated by Condensins and Ends with the Disentangling of Inter Sister Catenation Catalyzed by Topoisomerase Ii (topo Ii). 
    4712   Protein Serine/threonine/tyrosine Kinase Activity  Catalysis of the Reactions: ATP + a Protein Serine = Adp + Protein Serine Phosphate; ATP + a Protein Threonine = Adp + Protein Threonine Phosphate; and ATP + a Protein Tyrosine = Adp + Protein Tyrosine Phosphate.
