The Cell Cycle and Cancer

What is the longest phase of the cell cycle?

• Interphase

• Mitosis

• Prophase

• Metaphase

During which stage of mitosis do the sister chromatids get pulled apart?

• Prophase

• Metaphase

• Anaphase

• Telophase

What is the role of checkpoints in the cell cycle?

• To speed up cell division

• To ensure each phase is completed accurately

• To condense chromatin into chromosomes

• To break down the nuclear envelope

What can result from mutations in genes that regulate the cell cycle?

• Increased apoptosis

• Formation of tumors

• Slower cell growth

• Enhanced DNA repair

What is metastasis in the context of cancer?

• The formation of new blood vessels

• The spread of cancer cells to other parts of the body

• The shrinking of tumors

• The repair of damaged DNA
