Cell Cycle and Mitosis Flashcard

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What is cytokinesis?

Back

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

Front

What happens if mitosis occurs without cytokinesis?

Back

The resulting cell would have multiple nuclei.

Front

What is the role of mitosis in organisms?

Back

Mitosis is essential for growth, repair, and maintenance of tissues by producing new cells.

Front

What are the main phases of mitosis?

Back

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

Front

What occurs during prophase?

Back

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

Front

What occurs during anaphase?

Back

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

Front

What occurs during telophase?

Back

During telophase, the nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to de-condense.

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 in preparation for cell division.
