Study Notes
Healing the World
- Reducing rates of infectious diseases saves millions of lives and improves public health.
- Tailored treatments minimize health risks and side effects for individuals.
- Advanced diagnostic tools enhance the precision of disease detection.
Feeding the World
- Biotechnology improves crop insect resistance, enhances herbicide tolerance, and enables sustainable farming practices.
- Reduced agricultural chemical use leads to a healthier consumer market.
- Higher crop yields are achieved with fewer inputs and resources.
- Development of crops with enhanced nutritional profiles supports food security.
Biotechnology Overview
- Commercial exploitation of biological processes can be categorized into medicine, industry, environment, and agriculture.
- Genetic techniques can affect Earth's biodiversity, potentially leading to reduced genetic diversity, such as in dairy cows.
Medical Biotechnology
- GM foods can provide higher nutritional value, particularly benefiting third-world countries.
- Gene therapy shows potential but is still experimental; not all patients respond positively, and risks include tumor formation.
- Biotech enables efficient production of medicines like insulin.
- Cloning genes allows for the introduction of healthy genetic material into compromised cells.
Industrial Biotechnology
- Genetically modified (GM) plants may produce eco-friendly chemicals to replace non-renewable resources.
- Research includes developing organisms capable of absorbing heavy metals from contaminated sites.
- GM techniques can help control disease spread among livestock and create medications for disease resistance.
Gene Therapy
- Involves the insertion of healthy genes into organisms to repair or replace faulty genes and improve disease resistance.
- Can be performed on embryos to prevent hereditary diseases.
- Regulates gene expression without needing DNA from donors.
CRISPR Technology
- CRISPR is a method for precise DNA editing by cutting out or inserting nucleotide bases.
- Used to correct genetic defects, treating or preventing diseases.
- Develops new plant varieties that mimic outcomes of traditional breeding.
- Research includes GM mosquitoes carrying genes that cause premature deaths in offspring to control populations.
