Key Topics to Revise
1
Biotechnology and Genetic Engineering
- Biotechnology is the use of living organisms or their parts to create products and services beneficial to humans
- Genetic engineering involves creating desired traits in organisms by combining or deleting genes
- DNA structure discovery accelerated biotechnology growth
2
Recombinant DNA Technology
- Combines DNA segments from two or more different organisms to form recombinant DNA
- Uses restriction endonuclease enzymes (genetic scissors) to cut specific genes
- Ligase enzymes act as genetic glue to join DNA segments
3
CRISPR Technology
- Modern technology for precise DNA editing
- Based on natural bacterial defense mechanism against viruses
- Uses Cas9 enzyme as molecular scissors to cut DNA
4
Genetically Modified Organisms (GMOs)
- Organisms whose genetic constitution has been altered through genetic engineering
- Include plants, animals, and microorganisms
- Plant GMOs: pest resistance (Bt cotton), herbicide resistance (soybean), nutrient enrichment (golden rice)
