During which phase of the cell cycle does the cell replicate its DNA?

• G1 phase

• S phase

• G2 phase

• M phase

How does mitosis contribute to the growth of an organism?

• By producing gametes

• By increasing the number of cells

• By reducing the number of chromosomes

• By creating genetic diversity

What is the role of checkpoints in the cell cycle?

• To initiate cell death

• To ensure DNA is replicated correctly

• To stop cell division permanently

• To speed up the cell cycle

Which of the following best describes how cancer is related to cell division?

• Cancer cells divide uncontrollably due to a lack of regulation

• Cancer cells divide only when needed

• Cancer cells do not undergo mitosis

• Cancer cells have fewer chromosomes

How does mitosis aid in tissue repair after an injury?

• By forming scar tissue

• By replacing damaged cells with new cells

• By removing dead cells

• By preventing further cell division

What happens during the G2 phase of the cell cycle?

• The cell divides into two daughter cells

• The cell grows and prepares for mitosis

• The cell's DNA is replicated

• The cell undergoes apoptosis

Which of the following is a key difference between normal cell division and cancerous cell division?

• Normal cells divide faster than cancerous cells

• Cancerous cells ignore regulatory signals

• Normal cells do not undergo mitosis

• Cancerous cells have more chromosomes

What is the significance of the spindle fibers during mitosis?

• They help in the replication of DNA

• They attach to chromosomes and help separate them

• They form the cell membrane

• They dissolve the nuclear envelope

What phase of mitosis is pictured?

• Metaphase
• Telophase
• Prophase
• Anaphase
