Question 1 · 1 mark · Difficulty 1/3

Which of the following best defines genetic engineering?

  1. The selective breeding of organisms with desirable characteristics
  2. The transfer of genes from one organism to another to produce desired characteristics
  3. The natural mutation of DNA during cell division
  4. The cloning of organisms to produce genetically identical offspring
Show answer & explanation
✓ Answer: B — The transfer of genes from one organism to another to produce desired characteristics
Award 1 mark for recognising that genetic engineering involves the transfer of genes from one organism to another. A is incorrect because this describes selective breeding, not genetic engineering. C is incorrect because genetic engineering is a deliberate process, not natural mutation. D is incorrect because cloning produces identical copies but does not involve gene transfer between different organisms.
Question 2 · 1 mark · Difficulty 2/3

A pharmaceutical company in Switzerland produces human blood clotting factor VIII using genetically modified hamster cells grown in culture. Before genetic engineering was developed, factor VIII was extracted from donated human blood. What is the main advantage of producing factor VIII by genetic engineering rather than extraction from blood?

  1. It is cheaper to produce
  2. It reduces the risk of transmitting blood-borne diseases such as HIV and hepatitis
  3. The genetically engineered product works faster in the human body
  4. It produces a different form of factor VIII with fewer side effects
Show answer & explanation
✓ Answer: B — It reduces the risk of transmitting blood-borne diseases such as HIV and hepatitis
Award 1 mark for recognising that genetic engineering eliminates the risk of disease transmission from donated blood. A is incorrect because genetic engineering is often more expensive than extraction. C is incorrect because the genetically engineered factor VIII is identical to the human protein and works at the same rate. D is incorrect because the aim is to produce an identical protein, not a different form.

CIE IGCSE Biology: Genetic engineering and its applications FAQ

How many CIE IGCSE Biology questions on Genetic engineering and its applications are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Genetic engineering and its applications for CIE IGCSE Biology, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Genetic engineering and its applications practice with other Biology topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Genetic engineering and its applications questions aligned to the official CIE IGCSE Biology syllabus?
Every question is written against the published CIE IGCSE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is Genetic engineering and its applications typically tested on CIE IGCSE Biology papers?
Genetic engineering and its applications appears across multiple question types on real CIE IGCSE Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
