Biology: 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 original cell.

Front

What are the phases of the cell cycle?

Back

The cell cycle consists of interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What happens during cytokinesis?

Back

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

Front

What is the role of chromosomes during mitosis?

Back

Chromosomes ensure that DNA is accurately replicated and distributed to the daughter cells during cell division.

Front

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What happens during metaphase?

Back

During metaphase, chromosomes line up along the equatorial plane of the cell, preparing for separation.

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 occurs during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms, and the chromosomes begin to de-condense.

Front

How many chromosomes do daughter cells have after mitosis?

Back

Daughter cells have the same number of chromosomes as the original parent cell.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and tissue repair in organisms.
