Other questions in this quiz

2. When hybridoma cells divide, what do they produce?

  • Monoclonal antibodies
  • Antigens
  • Anti-toxins

3. Why are cancer cells used in the production of monoclonal antibodies?

  • They replicate quickly
  • They can produce anti-toxins to neutralise toxins produced by pathogens
  • They make antibodies

4. Can you treat cancerous tumours with monoclonal antibodies?

  • Yes
  • No

5. How are monoclonal antibodies used in pregnancy tests?

  • The hormone HGH or hCG in urine binds to mobile antibodies. The bound antibody then attaches to an immobilised antibody, producing a colour change.
  • Monoclonal antibodies in the urine bind to hCG on the pregnancy stick, producing a line.
