Phases of Mitosis

Front

What is the first stage of mitosis?

Back

Prophase

Front

What happens during prophase?

Back

Chromatin condenses into chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite ends of the cell.

Front

What is the second stage of mitosis?

Back

Metaphase

Front

What occurs during metaphase?

Back

Chromosomes line up at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is the third stage of mitosis?

Back

Anaphase

Front

What happens during anaphase?

Back

Sister chromatids are pulled apart and move toward opposite poles of the cell.

Front

What is the fourth stage of mitosis?

Back

Telophase

Front

What occurs during telophase?

Back

Chromatids reach the poles, the nuclear envelope re-forms, and chromosomes begin to de-condense.

Front

What is cytokinesis?

Back

The process that divides the cytoplasm of a parental cell into two daughter cells.
