Its "A" portion is explained by the "Pac-Man" or poleward-flux models. In S. cerevisiae, the Mad and Bub genes regulate a checkpoint that controls the onset of this stage that is released by the action of a protein complex containing Cdc27. The breakdown of securin indirectly activates the FEAR pathway during its early steps, and the ensuing release of separase also promotes the breakdown of cohesin and the separation of paired sister chromatids after they line up on the metaphase plate. FTP, identify this stage of mitosis which precedes telophase.
