The 20 questions

  1. What does genome sequencing determine in an organism's DNA?

    • Amino acid sequence
    • Chromosome number
    • Protein tertiary structure
    • Order of bases
  2. What is the definition of personalised medicine in healthcare?

    • Universal drug treatment
    • Tailored genetic healthcare
    • Mass vaccination programmes
    • Gene replacement therapy
  3. How does genome sequencing help doctors choose the best drug?

    • Cures genetic mutations
    • Predicts drug response
    • Prevents drug breakdown
    • Synthesises targeted drugs
  4. Which technology made genome sequencing significantly faster and cheaper?

    • Polymerase chain reaction
    • Gel electrophoresis
    • Next-generation sequencing
    • DNA microarrays
  5. What is a major ethical concern regarding stored genomic data?

    • Data privacy breaches
    • Slow processing speeds
    • Inaccurate sequence data
    • High storage costs
  6. Which ethical issue is created by high costs of personalised treatments?

    • Genetic discrimination
    • Lack of consent
    • Inaccurate diagnostic testing
    • Unequal healthcare access
  7. What should personalised medicine provide if a drug is predicted to fail?

    • Unchanged drug regimen
    • Immediate gene therapy
    • Increased drug dosage
    • Alternative drug treatment
  8. Why is identifying disease risk before symptoms appear beneficial?

    • Cures genetic defects
    • Reverses gene mutations
    • Enables early intervention
    • Guarantees total immunity
  9. Why does genome sequencing rarely predict complex diseases with total certainty?

    • Genes degrade rapidly
    • DNA sequences mutate
    • Sequencing is inaccurate
    • Environmental factors contribute
  10. Which situation represents an example of genetic discrimination?

    • Failed gene therapy
    • Ineffective drug prescriptions
    • Random gene mutations
    • Unfair insurance terms
  11. What is the primary purpose of informed consent in genome sequencing?

    • Protecting physical samples
    • Guaranteeing test accuracy
    • Reducing sequencing costs
    • Ensuring participant agreement
  12. What does finding a gene variant associated with a disease mean?

    • Certain disease outcome
    • Direct single cause
    • Complete disease immunity
    • Increased disease risk
  13. How did the Human Genome Project support personalised medicine?

    • Eradicated genetic diseases
    • Created gene editing
    • Automated drug manufacturing
    • Provided reference sequence
  14. Which factor most limits the widespread use of personalised medicine?

    • High overall cost
    • Lack of DNA
    • Low genetic diversity
    • Inaccurate sequencing techniques
  15. What type of genetic test determines how a patient processes a drug?

    • Pharmacogenetic test
    • Blood glucose test
    • Serological antibody test
    • DNA fingerprinting test
  16. Which ethical issue involves sharing individual genetic data without explicit consent?

    • Genetic discrimination
    • Gene silencing
    • Breach of privacy
    • DNA degradation
  17. A genetic test result showing a 30% chance of disease represents a measure of what?

    • Absolute certainty
    • Zero probability
    • Guaranteed diagnosis
    • Disease risk
  18. What factor could prevent equal patient access to personalised medicines?

    • Faster approval times
    • Increased DNA stability
    • Low drug specificity
    • High treatment costs
  19. How many sequencing runs are needed to read 5 million fragments if one run reads 1 million?

    • 10 runs
    • 50 runs
    • 1 run
    • 5 runs
  20. Which ethical issue refers to using genetic data to deny insurance or employment?

    • Somatic therapy
    • Informed consent
    • Gene editing
    • Genetic discrimination
