MITOSIS

Front

What is mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What happens during prophase?

Back

During prophase, the chromosomes condense and become visible, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

What occurs during metaphase?

Back

During metaphase, the chromosomes line up along the equatorial plane of the cell, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is the role of anaphase in mitosis?

Back

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

Front

What happens during telophase?

Back

During telophase, the chromosomes reach the poles, begin to de-condense, and the nuclear envelope re-forms around each set of chromosomes, resulting in two nuclei.

Front

What is cytokinesis?

Back

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

Front

Why is mitosis important for growth and repair?

Back

Mitosis is essential for growth and repair because it allows for the production of new cells to replace damaged or dead cells.

Front

True or False: Mitosis results in cells with different DNA.

Back

False. Mitosis results in two daughter cells with the same DNA as the parent cell.

Front

What is the significance of the chromosome number in mitosis?

Back

The chromosome number is significant because it ensures that each daughter cell receives the correct number of chromosomes, maintaining genetic stability.
