TOPIC 9 DAY 2 MITOSIS AND CYTOKINESIS

Front

What is mitosis?

Back

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

Front

What occurs during the prophase stage of mitosis?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope begins to break down, and the spindle fibers start to form.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers help separate the chromosomes during mitosis by attaching to the centromeres and pulling the sister chromatids apart.

Front

What is the significance of the centromere?

Back

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

Front

What happens 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 the sister chromatids are pulled apart to opposite poles of the cell.

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.

Front

How many chromosomes do daughter cells have after mitosis?

Back

Daughter cells produced by mitosis have the same number of chromosomes as the parent cell.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis refers to the division of the nucleus, while cytokinesis refers to the division of the cytoplasm and the formation of two separate daughter cells.
