Molecular Genetics: DNA Technology

Unlocking the Power of DNA

Molecular genetics uses technology to study and change DNA. Techniques like genetic engineering and CRISPR let scientists add, remove, or modify genes.

Applications

  • Genetically Modified Organisms (GMOs): Crops with added genes for resistance to pests or improved nutrition.
  • Gene Therapy: Treating diseases by correcting faulty genes.
  • DNA Fingerprinting: Identifying individuals using unique patterns in their DNA.

Ethical Considerations

With these technologies come important questions about safety, privacy, and the impact on society.

DNA technology helps cure diseases, solve crimes, and feed the world, but also requires careful ethical decisions.

Examples

  • CRISPR technology is used to edit genes in plants and animals.

  • DNA fingerprinting helps identify suspects in forensic investigations.

In a Nutshell

DNA technology allows scientists to edit genes and solve real-world problems.
