Cell Cycle and mitosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the stages of mitosis?

Back

The 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 spindle apparatus begins to form.

Front

What is the role of the centromere?

Back

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

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What happens during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is the significance of the 'S' phase in the cell cycle?

Back

The 'S' phase is significant because it is when DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.

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

How does mitosis contribute to growth and repair?

Back

Mitosis allows for the production of new cells, which is essential for growth, tissue repair, and regeneration.
