Understanding the Cell Cycle

What is the primary purpose of the cell cycle?

• To produce energy for the cell

• To destroy damaged cells

• To replace old cells and allow growth

• To create new organisms

During which phase does the cell duplicate its genetic material?

• S Phase

• M Phase

• G1 Phase

• G2 Phase

What happens if a cell fails the G1/S checkpoint?

• It immediately divides

• It proceeds to mitosis

• It enters the G0 phase

• It undergoes apoptosis

What is the role of spindle fibers during metaphase?

• To condense genetic material

• To attach to chromatids and prepare for separation

• To dissolve the nuclear membrane

• To replicate DNA

What condition can result from an error at the M checkpoint?

• Cancer

• Necrosis

• Aneuploidy

• Apoptosis
