The Cell Cycle--Mitosis Practice Questions

What are the four phases of the cell cycle?

• Cytokinesis, Mitosis, Interphase, Prophase

• Prophase, Metaphase, Anaphase, Telophase

• G1, S, G2, M

• Interphase, Prophase, Metaphase, Anaphase

During which phase do chromosomes become visible and most condensed?

• Prophase

• Telophase

• Anaphase

• Metaphase

What happens during Anaphase?

• Chromosomes line up across the center of the cell

• A nuclear envelope develops around the chromosomes

• The cell membrane pinches together in the middle

• Sister chromatids separate into individual chromosomes and move to the poles

How does cytokinesis differ between animal and plant cells?

• In animal cells, the cell membrane pinches together, while in plant cells, a cell plate forms

• In animal cells, a cell plate forms, while in plant cells, the cell membrane pinches together

• Both animal and plant cells pinch the cell membrane together

• Both animal and plant cells form a cell plate

What is the role of mitosis in asexual reproduction?

• It reduces the chromosome number by half

• It allows for sexual reproduction

• It increases genetic diversity

• It maintains the chromosome number across generations

Which phase of mitosis is characterized by the alignment of chromosomes at the cell's equator?

• Prophase

• Metaphase

• Anaphase

• Telophase

What is the primary purpose of the S phase in the cell cycle?

• To divide the cell into two daughter cells

• To replicate the cell's DNA

• To produce cellular organelles

• To reduce the chromosome number by half

Which of the following best describes the G0 phase?

• A phase where the cell prepares for DNA replication

• A phase where the cell divides into two daughter cells

• A resting phase where the cell is not actively preparing to divide

• A phase where the cell's DNA is replicated

What is the significance of the G2 phase in the cell cycle?

• To replicate the cell's organelles and ensure the cell is ready for mitosis

• To reduce the chromosome number by half

• To initiate the cell's entry into mitosis

• To divide the cell into two daughter cells

What role do centrioles play during mitosis?

• They replicate the cell's DNA

• They assist in cell membrane pinching

• They help in the formation of the spindle fibers

• They reduce the chromosome number by half
