For 10 points, name this stage of mitosis where chromosomes line up along the center of the cell, immediately preceding anaphase.
In S. cerevisiae, CIM3 and CIM5 protease mutants arrest cells during this event, which is typically ended when Esp1associates with Scc1, part of a cascade triggered by APC, which ubiquitinates (*) cohesins. It is characterized by treadmilling through the constant addition and removal of tubulin, thus maintaining microtubule length. This stage is followed by microtubule shortening and is immediately preceded by attachment at the kinetochore, which allows chromosomes to move to its namesake plate.
