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.

Prophase: Chromosomes condense, envelope breaks.

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

In prophase, chromosomes condense and nuclear envelope breaks. In metaphase, chromosomes line up at cell center. In anaphase, sister chromatids separate and move apart. In telophase, nuclear envelope reforms and cell divides.

During cell division, there are four main phases: prophase, metaphase, anaphase, and telophase. To shorten the description:

- Prophase: chromosomes condense, nuclear envelope breaks down.
- Metaphase: chromosomes align at center of the cell.
- Anaphase: sister chromatids separate and move to opposite ends.
- Telophase: nuclear envelope reforms and cell division begins.
