Cell Cycle, Mitosis, Homeostasis Checkpoint

Front

What is the cell cycle?

Back

The cell cycle is the series of stages that a cell goes through to grow and divide, including interphase, mitosis, and cytokinesis.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, 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

Define 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 cytokinesis?

Back

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

Front

What is homeostasis?

Back

Homeostasis is the tendency of an organism to maintain a stable internal environment despite external changes.

Front

What role do checkpoints play in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle, preventing errors such as DNA damage.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is the significance of the G1 phase?

Back

The G1 phase is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.
