Biotechnology Notes

Biotechnology Overview

  • Biotechnology involves using living systems to develop products.

Genetic Engineering Techniques

  • CRISPR Gene Editing: Uses Cas9 protein and RNA to edit genes.

    • Steps:

    1. Form Cas9-RNA complex.

    2. Attach to target DNA.

    3. Cut DNA with Cas9.

    4. Insert new DNA.

  • Specificity: Enables targeted and precise DNA modifications.

Applications in Agriculture

  • GMOs: Examples include corn, soybean, cotton, potato, and papaya.

    • Uses: 95% as animal feed and ingredients in processed foods.

  • Characteristics:

    • Insect resistance (e.g., Bt-Eggplant) and disease resistance (e.g., GM Papaya).

Regulatory Framework of GMOs

  • Regulation: Overseen by multiple federal agencies ensuring safety for health and environment.

  • GMO Labels: Indicate whether products are non-GMO or contain genetically engineered ingredients.

Future of Gene Therapy

  • Current Applications: Treating certain cancers and genetic disorders like Sickle Cell Disease.

  • Potential: Future uses could expand to more cancers, Type 1 Diabetes, and Parkinson’s Disease.

  • Conclusion: Gene therapy and genetic engineering have significant potential to impact medicine and agriculture.
