What is cancer?

• An infectious disease

• Regular cell growth

• Controlled cell division

• Unregulated cell growth and division

Answer explanation

Cancer cells are cells that divide uncontrollably and invade surrounding tissues, often spreading via blood or lymph systems. Triggered by DNA mutations in the genes that control cell division, these cells ignore signals to stop dividing, resulting in a growing mass of cells known as a tumor.

The cell spends most of its time in which phase?

• prophase

• interphase

• metaphase

• cytokinesis

Place the stages of cell division in correct order.

• Anaphase

• Metaphase

• Telophase

• Cytokinesis

Answer explanation
