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 purposes of mitosis in the human body?

Back

The main purposes of mitosis are growth and repair of tissues.

Front

How many stages are there in mitosis, and what are they?

Back

There are five stages in mitosis: prophase, metaphase, anaphase, telophase, and cytokinesis.

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

Front

What is the significance of anaphase in mitosis?

Back

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

Front

What happens 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.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

How many chromosomes are present in a human somatic cell?

Back

A human somatic cell contains 46 chromosomes.

Front

Where is genetic material located in a cell?

Back

Genetic material is located in the nucleus of the cell.
