Cell Cycle Flashcard Review

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase and the mitotic phase.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (Mitosis and Cytokinesis).

Front

What happens during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope begins to break down, and spindle fibers start to form.

Front

What is Metaphase?

Back

Metaphase is the stage of mitosis where chromosomes line up at the cell's equator, and spindle fibers attach to the centromeres of the chromosomes.

Front

What occurs during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell as the spindle fibers shorten.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where the chromosomes reach the poles, the nuclear envelope re-forms, and the chromosomes begin to de-condense.

Front

How many chromosomes do human body cells have?

Back

Human body cells have 46 chromosomes, arranged in 23 pairs.

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 spindle fibers?

Back

Spindle fibers are crucial for separating chromosomes during cell division, ensuring that each daughter cell receives the correct number of chromosomes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.
