Questions and Answers

Within gene therapy, what is the primary purpose of replacing defective genes with healthy ones?

  • To correct genetic disorders by restoring normal gene function. (correct)
  • To create genetic mutations that increase genetic diversity.
  • To introduce entirely new genes for research purposes only.
  • To enhance desirable traits beyond normal genetic function.

Which application of genetic modification involves altering an organism's genetic material to improve its traits or capabilities in industry or agriculture?

  • Creating exact duplicates of organisms for research.
  • Introducing foreign genes into an organism to confer specific traits. (correct)
  • Developing new methods of asexual reproduction.
  • Eliminating genetic variation to stabilize populations.

The study of genetic code modification plays a role in producing intact proteins; what other application relies on understanding the human genome?

  • Determining paternity and aiding in crime detection. (correct)
  • Predicting future evolutionary pathways of species.
  • Enhancing individual physical and mental capabilities.
  • Creating personalized educational curricula based on genetic predispositions.
