Mitosis

Front

What is the definition of mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring that each new cell receives an exact copy of the parent cell's DNA.

Front

What are the main phases of mitosis?

Back

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

Front

What is the role of the centromere during mitosis?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and is crucial for the proper segregation of chromosomes during cell division.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope begins to break down, and the mitotic spindle starts 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 function of centrioles in mitosis?

Back

Centrioles help organize the mitotic spindle and are involved in the formation of spindle fibers that separate chromosomes during cell division.

Front

Describe anaphase in mitosis.

Back

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

Front

What is telophase?

Back

Telophase is the final stage of mitosis where 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 and how does it relate to mitosis?

Back

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

Front

What is the significance of spindle fibers in mitosis?

Back

Spindle fibers are essential for the movement of chromosomes during mitosis, ensuring that each daughter cell receives the correct number of chromosomes.
