shorten this as much as possible In prophase, the chromosomes condense and the nuclear envelope breaks down. In metaphase, the chromosomes line up at the center of the cell. In anaphase, the sister chromatids separate and are pulled to opposite ends of the cell. In telophase, the nuclear envelope reforms around each set of chromosomes and the cell begins to divide.

Answer 1

Prophase: Chromosomes condense, envelope breaks.
Metaphase: Chromosomes align at center.
Anaphase: Sister chromatids separate, pulled apart.
Telophase: Envelope reforms, cell divides.
