Microscopic view of Cell Division Interphase: Period between Two M Phases.
,yjdl,utde.jufr Cytokinesis Mitosis DNA Replication
G1 checkpoint • Start 1 • Is cell big enough? • Is environment favorable? • G2 checkpoint • Enter M1 • Is DNA replicated? • Is environment favorable? • Is cell big enough? • Metaphase checkpoint • Exit from M1 • Are all chromosomes aligned on spindle?
S.pombe cdc2 mutants (Wild-type) (Cannot enter Mitosis) (Enters mitosis Early)
