Unit 2: Cells, Cell Cycle, and Cell Differentiation Test Review

Front

What is the function of Prophase in Mitosis?

Back

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, the cell replicates its DNA, ensuring that each daughter cell will have an identical set of chromosomes.

Front

What is the significance of the G0 phase in the cell cycle?

Back

The G0 phase is a resting state where cells are not actively preparing to divide but are performing their regular functions.

Front

What happens during Anaphase in Mitosis?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell, ensuring that each new cell will receive an identical set of chromosomes.

Front

What is the role of Telophase in Mitosis?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is Cytokinesis?

Back

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

Front

What is the difference between Mitosis and Meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes.

Front

What are the main phases of the cell cycle?

Back

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

Front

What is the purpose of the cell cycle checkpoints?

Back

Cell cycle checkpoints are mechanisms that monitor the progression of the cell cycle and ensure that each phase is completed accurately before moving to the next.

Front

What is the role of spindle fibers during Mitosis?

Back

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