      Question 4

      Marks: 1

      Which of the following provides the best explanation of how cyclins were discovered?

      • It was discovered when Robert Hooke researched how proteins drive the progress of the different phases of the cell cycle

      • It was discovered accidentally when a group of German scientists studied the chromosomes of horse threadworms

      • It was discovered when Matthias Schleiden and Theodor Schwann studied animal and plant cells under a microscope

      • It was discovered by chance when Tim Hunt researched protein synthesis in sea urchin eggs

      Question 5

      Marks: 1

      The following steps are involved in the formation of malignant tumours.

      1. Tumour cells spread in blood and lymph
      2. Rapid mitosis occur
      3. Oncogenes arise due to exposure to carcinogens
      4. The tumour increases in size
      5. Tumour cells form secondary tumours throughout the body

      Which would represent the correct order of the steps?

      • 2 → 4 → 3 → 1 → 5

      • 3 → 2 → 4 → 1 → 5

      • 4 → 2 → 3 → 1 → 5

      • 3 → 2 → 1 → 4 → 5
