Questions and Answers

What is the primary goal of gene therapy?

  • To make a beneficial protein to compensate for abnormal genes
  • To introduce a new gene into the body to help fight a disease
  • To use drugs or surgery to treat a disorder
  • To replace a mutated gene that causes disease with a healthy copy of the gene (correct)
  • What is the current status of gene therapy?

  • It has been proven to be completely safe and effective
  • It has been abandoned due to its risks
  • It is still under study to ensure its safety and effectiveness (correct)
  • It is widely used to treat many diseases
  • What is the role of viruses in gene therapy?

  • They are used to make beneficial proteins
  • They are used to deliver new genes into cells (correct)
  • They are used to replace mutated genes
  • They are used to inactivate faulty genes
  • What type of diseases is gene therapy currently being tested for?
