    Study Notes

    Basis of Genetic Engineering

    • Genetic Engineering is based on the ability to manipulate DNA molecules.

    Genetic Engineering in Plants

    • Genetic Engineering in plants allows for the introduction of desirable traits such as pest resistance and drought tolerance.

    Applications of DNA-Based Technology

    • One application of DNA-Based Technology is the production of genetically engineered insulin.

    Traits in Transgenic Crops

    • Pest resistance is a trait incorporated in Transgenic Crops.

    Common Property of Cells/Organisms

    • All cells or organisms share the common property of having DNA as their genetic material.

    Genetically Modified Organisms

    • E. coli is not mentioned as a Genetically Modified Organism in the text.

    Applications of DNA-Based Technology in Health and Medicine

    • One application of DNA-based technology in the field of health and medicine is the production of genetically engineered insulin.

    DNA Fingerprinting in Legal/Law Applications

    • DNA fingerprinting primarily serves in the identification of criminals.

    Biopharming

    • Goats are specifically mentioned as being used for biopharming.

    DNA Technology's First Drug

    • Insulin was highlighted as DNA technology's first drug.

    Gene Therapy

    • The purpose of gene therapy is to treat genetic disorders by replacing or repairing faulty genes.

    Applications of DNA-Based Technology

    • DNA fingerprinting is an application of DNA-based technology that involves identifying criminals.

    Recombinant DNA Technology

    • The main purpose of Recombinant DNA Technology is to produce recombinant DNA molecules.

    Enzymes in Gene Splicing
