1 Warm-up (Thurs)Your mother is worried because she heard that the chickenpox vaccine your younger brother is going to receive is actually a weakened form of the virus that causes chickenpox. How do you explain to her that being injected with the disease will actually help protect your brother?
2 Warm-up (Friday)The doctors suggest that people get a new flu vaccine each year. Why do you think this is?
3 Anything in Red you write! BiotechnologyAnything in Red you write!
4 BiotechnologyBiotechnology is the use of living organisms to solve problems and make useful products.Selective breeding/ artificial selection=process by which humans breed other animals and plants for particular traitsGenetic modification= change genetic materialDNA fingerprintingAnimal Cloning= copy of another organismBioremediation= bacteria cleans environment
5 Biotechnology is not just one technology, but many 3 basic kinds: Working with cellsWorking with proteinsWorking with genes
6 Biotechnology in Agriculture Scientists are looking for ways to alter crops to make them resistant to disease, herbicides (things that kill plants) and frost.Food crops are also manipulated to taste better or to not rot as fast or grow faster.Genetically engineered (in labs)GLOW!!!!
7 the microbial world has led to the emerging field of biotechnology which has given us many advances and new careers inmedicineagriculturegeneticsfood science.
8 How does this affect the world? health care is developing better ways to diagnose, treat, and prevent disease.The food and agriculture industries are rapidly adopting the tools of biotechnology.Energy and environment clean up
9 How does it work… Uses of modern biotechnology include: making medicine in large quantitiese.g. making penicillin in bacteria and human insulin for the treatment of diabetescombating crime through DNA testing and forensic testingremoving pollution from soil and water (bioremediation)improving the quality of agricultural crops and livestock products by selecting breeding.
10 Disadvantages Cloning is controversial Might cause more or different diseasesHealth insurance issues
11 READ ONLY: Bioremediation Bacteria clean up the environmentemerge in energy and the environment, where living cells and their molecules can help us develop new methods to clean up our environment, detect environmental contamination, and reduce our dependence on petroleum
12 READ ONLY!!! Selective Breeding in Agriculture Ancient farmers in what is now Mexico took the first steps in domesticating maize when they simply chose which kernels (seeds) to plant. These farmers noticed that not all plants were the same. Some plants may have grown larger than others, or maybe some kernels tasted better or were easier to grind. The farmers saved kernels from plants with desirable characteristics and planted them for the next season's harvest.
13 Increasing crop production Reducing the loss of crops to insects 2. Which of these is a concern about biotechnology?1. Which of these is not a way in which biotechnology can benefit agriculture?Increasing crop productionReducing the loss of crops to insectsProducing better-tasting fruitsImproving farm machineryA. Increased crop yield
