Front

What are the phases of mitosis?

Back

Prophase, Metaphase, Anaphase, Telophase.

Front

What happens during prophase?

Back

The nuclear membrane breaks down, and chromosomes condense and become visible.

Front

What happens during metaphase?

Back

Chromosomes align in the middle of the cell, attached to spindle fibers.

Front

What happens during anaphase?

Back

Sister chromatids are pulled apart to opposite ends of the cell.

Front

What happens during telophase?

Back

The nuclear membrane re-forms around each set of chromosomes, which begin to de-condense.

Front

What is the longest phase of the cell cycle?

Back

Prophase is often the longest phase because the nuclear membrane must break down.
