Mitosis Flashcard

Front

What are checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms in the cell cycle that ensure the cell is ready to proceed to the next stage and prevent the division of damaged or unprepared cells.

Front

What occurs during metaphase in mitosis?

Back

During metaphase, chromosomes line up along the metaphase plate in the middle of the cell.

Front

How is the cell cycle regulated?

Back

The cell cycle is regulated by checkpoints and regulatory proteins that monitor and control the progression of the cell cycle.

Front

What is cytokinesis?

Back

Cytokinesis is the process of dividing the cytoplasm to form two separate daughter cells after mitosis.

Front

What happens during prophase in mitosis?

Back

During prophase, chromatin condenses into chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers help separate the chromosomes during cell division by attaching to the centromeres and pulling them apart.

Front

What is the significance of the nuclear envelope during mitosis?

Back

The nuclear envelope breaks down during prophase to allow the chromosomes to be accessed and separated during mitosis.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the process of nuclear division, while cytokinesis is the process of cytoplasmic division that follows mitosis.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome that are joined together by a centromere and are separated during mitosis.

Front

What is anaphase in mitosis?

Back

Anaphase is the stage in mitosis where sister chromatids are pulled apart to opposite ends of the cell.
