The Cell Cycle, Mitosis and Meiosis

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation until it divides into two daughter cells. It includes interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (Mitosis and Cytokinesis).

Front

What occurs during Prophase I of meiosis?

Back

During Prophase I of meiosis, homologous chromosomes pair up and exchange genetic material through a process called crossing over.

Front

What is crossing over and when does it occur?

Back

Crossing over is the exchange of genetic material between homologous chromosomes that occurs during Prophase I of meiosis.

Front

What happens during Anaphase of mitosis?

Back

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

Front

What is the significance of Metaphase in mitosis?

Back

In Metaphase, chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes during division.

Front

List the stages of mitosis in order.

Back

The stages of mitosis in order are Prophase, Metaphase, Anaphase, and Telophase.

Front

How many chromosomes do human daughter cells have after mitosis?

Back

Human daughter cells have 46 chromosomes after mitosis, which is the same number as the parent cell.

Front

How many chromosomes do human daughter cells have after meiosis?

Back

Human daughter cells have 23 chromosomes after meiosis, which is half the number of the parent cell.

Front

What is the role of cytokinesis in the cell cycle?

Back

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells, completing cell division.
