mitotic cell cycle GO:0000278 GO:0007067 Note that this term should not be confused with 'GO:0140014 ; mitotic nuclear division'. 'GO:0000278 ; mitotic cell cycle represents the entire mitotic cell cycle, while 'GO:0140014 ; mitotic nuclear division' specifically represents the actual nuclear division step of the mitotic cell cycle. Progression through the phases of the mitotic cell cycle, the most common eukaryotic cell cycle, which canonically comprises four successive phases called G1, S, G2, and M and includes replication of the genome and the subsequent segregation of chromosomes into daughter cells. In some variant cell cycles nuclear replication or nuclear division may not be followed by cell division, or G1 and G2 phases may be absent. Wikipedia:Mitosis biological_process mitosis cell cycle
