What to Focus On
- Environmental biotechnology uses biological systems to address pollution
- Biofuels include biodiesel, bioalcohol, biogas, and biomass
- Biodiesel is produced through trans-esterification of oils and fats
- GM crops provide herbicide tolerance, disease resistance, and stress tolerance
- Bt crops express insecticidal proteins from Bacillus thuringiensis
- CRISPR-Cas9 enables precise genome editing in plants
- Three types of transplantation: autograft, allograft, and xenograft
- Stem cells can proliferate and differentiate to replace damaged cells
- Organoids are 3D self-organized tissue models from stem cells
Common Mistakes to Avoid
All biofuels are environmentally friendly and completely replace the need for fossil fuels without any drawbacks
GM crops are only about pest resistance (Bt crops) and herbicide tolerance - they cannot address nutritional deficiencies or environmental stress
Nanobiotechnology and nanotechnology are the same thing, just applied to biological systems
Memory Tips
Four main types of biofuels
Transesterification process for biodiesel
CRISPR-Cas9 components and function
Three types of organ transplantation
