Cell Cycle and Mitosis Review

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through to grow and divide, ultimately leading to the formation of new daughter cells.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (which includes G1, S, and G2 phases) and the Mitotic phase (which includes mitosis and cytokinesis).

Front

What happens during interphase?

Back

During interphase, the cell grows, replicates its DNA, and prepares for mitosis.

Front

What is cytokinesis?

Back

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

Front

What occurs during prophase?

Back

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

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 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

What is the significance of the S phase in interphase?

Back

The S phase is significant because it is the stage where DNA replication occurs, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What are sister chromatids?

Back

Sister chromatids are two identical copies of a single chromosome that are connected by a centromere.
