A researcher compares traditional chemotherapy (which affects all rapidly dividing cells) with monoclonal antibody therapy targeting cancer cells. Which statement best evaluates an advantage of monoclonal antibody therapy?

Q: How do I try a free AQA Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live AQA GCSE Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for AQA Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the AQA GCSE syllabus?

Every question is written against the published AQA GCSE Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A researcher compares traditional chemotherapy (which affects all rapidly dividing cells) with monoclonal antibody therapy targeting cancer cells. Which statement best evaluates an advantage of monoclonal antibody therapy?

Accepted Answer

B. It targets only cancer cells, reducing harm to healthy rapidly dividing cells — A key advantage of monoclonal antibody therapy is its specificity — antibodies are designed to bind to antigens unique to cancer cells, sparing healthy rapidly dividing cells such as those in hair follicles and the gut lining. Monoclonal antibodies are generally more expensive to produce than conventional drugs, do not cure all cancers, and their primary action is direct targeting rather than stimulating general immunity.

Answer

A. It is cheaper to produce than chemotherapy drugs

Answer

C. It permanently cures all types of cancer in all patients

Answer

D. It works by stimulating the patient's own immune system to destroy tumours

Answer

B. It targets only cancer cells, reducing harm to healthy rapidly dividing cells
