Understanding the Cell Cycle and Mitosis

What is the primary purpose of mitosis in the cell cycle?

• To repair damaged DNA

• To separate and pass on a complete genome to daughter cells

• To create genetic diversity

• To produce energy for the cell

During which stage of mitosis do spindle fibers attach to centromeres?

• Anaphase

• Metaphase

• Telophase

• Prophase

What happens to the sister chromatids during anaphase?

• They are pulled toward opposite poles of the cell

• They line up in the middle of the cell

• They condense into chromosomes

• They form new nuclei

How does the chromosome number change during anaphase?

• It remains the same

• It doubles due to replication

• It halves

• It doubles due to the separation of duplicated chromosomes

What can result from disruptions in the cell cycle?

• Increased cell energy

• Improved genetic diversity

• Uncontrollable cell division or apoptosis

• Enhanced tissue repair
