Questions and Answers

What is the primary concern with gene therapy in terms of its duration?

  • It requires frequent injections
  • It is too expensive to be a viable treatment option
  • Its short-lived nature makes it difficult to achieve long-term benefits (correct)
  • Its permanence can lead to unintended consequences

    • What is a major challenge in using viral vectors for gene therapy?

  • They can only be used for gene augmentation
  • They can only be used for gene correction
  • They can be used to cure any genetic disorder
  • They can cause toxicity, immune, and inflammatory responses (correct)

    • What is an example of gene correction in gene therapy?

  • Reverting a specific mutation in a gene (correct)
  • Introducing a healthy gene to replace a faulty one
  • Introducing a killer gene to target specific cells
  • Deleting a faulty gene
