Cell Cycle Review

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and Mitotic Phase (M), which includes prophase, metaphase, anaphase, and telophase.

Front

What occurs 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 happens during metaphase?

Back

During metaphase, chromosomes line up at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is the significance of anaphase?

Back

Anaphase is significant because it is the stage where sister chromatids are pulled apart to opposite poles of the cell, ensuring each new cell will receive an identical set of chromosomes.

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 telophase, where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the role of the spindle apparatus?

Back

The spindle apparatus is responsible for separating chromosomes during cell division by attaching to the centromeres and pulling them apart.

Front

How does the cell cycle ensure proper cell division?

Back

The cell cycle includes checkpoints that monitor the progression of the cell through its phases, ensuring that DNA is replicated correctly and that the cell is ready to divide.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the process of nuclear division, while cytokinesis is the division of the cytoplasm, resulting in two separate cells.

Front

What is the G1 phase of interphase?

Back

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