Mitosis AP Biology

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, involving several phases: prophase, metaphase, anaphase, and telophase.

Front

What occurs during Telophase?

Back

During Telophase, the nuclear envelope reforms around the separated chromosomes, which begin to de-condense back into chromatin.

Front

What is the role of Anaphase in Mitosis?

Back

Anaphase is the phase where microtubules pull sister chromatids apart to opposite poles of the cell, ensuring each new cell will receive an identical set of chromosomes.

Front

What is the M checkpoint?

Back

The M checkpoint ensures that all microtubules are properly attached to kinetochores before the cell proceeds with division.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the formation of sister chromatids for each chromosome.

Front

What is the G2 checkpoint?

Back

The G2 checkpoint verifies that all DNA has been replicated correctly and checks for any DNA damage before the cell enters mitosis.

Front

What is Prophase?

Back

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, and the mitotic spindle begins to form.

Front

What is Metaphase?

Back

Metaphase is the stage of mitosis where chromosomes align at the cell's equatorial plane, preparing for separation.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints are critical control mechanisms that ensure the cell cycle progresses only when conditions are favorable and all processes are completed correctly.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate daughter cells.
