Currently, the only exception to our feedback view of irreversible transitions in the cell cycle is the separation of sister chromatids at anaphase, which is accomplished by the proteolysis of ...

Anaphase: Students will see that the chromosomes have divided ... Telophase: Have students compare the progression through the cell cycle up to this point. Have them identify patterns in how the ...

The membrane around the nucleus disappears. Metaphase Chromosomes and their copies line up in the middle of the cell. Anaphase Chromosomes and their copies are pulled to different ends of the cell.
