Mitosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single 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 chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle 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 anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during telophase?

Back

During telophase, the chromosomes de-condense back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares for cytokinesis.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.

Front

Why is DNA replication important before mitosis?

Back

DNA replication is crucial before mitosis to ensure that each daughter cell receives an identical set of genetic information.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid by a centromere.

Front

What is the significance of identical daughter cells in mitosis?

Back

Identical daughter cells are important for growth, repair, and maintenance of tissues, ensuring that genetic information is preserved.
