Mitosis

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

What are the main phases of Mitosis?

Back

The main phases of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined and where the spindle fibers attach during cell division.

Front

What happens during Anaphase?

Back

During Anaphase, the sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

How many chromosomes do daughter cells have after Mitosis?

Back

Daughter cells have the same number of chromosomes as the parent cell. For example, if a fruit fly has 8 chromosomes, each daughter cell will also have 8 chromosomes after Mitosis.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows Mitosis, where the cytoplasm of the parent cell divides, resulting in two separate daughter cells.

What is the difference between Mitosis and Meiosis?

Back

Mitosis results in two identical daughter cells, while Meiosis results in four genetically diverse gametes with half the number of chromosomes.
