What is Biotechnology? “[A]ny technology based on a biological system or organism.” Examples of biological systems or organisms? Uses organisms to solve real world human problems and make useful products. Can you think of recent items in the news that may represent biotechnology? Bioengineers apply engineering principles (science & math to solve a problem) to living systems to create products & processes. What fields of science would be used by a bioengineer?

Biotechnology is used in.. Medicine Microbiology Agriculture - Livestock and Food Production

Biotechnology In Medicine Biotechnology has played a significant role in modern medicine. Many medical advancements involve the identification, use and manipulation of genes. Genetic Testing -- using a DNA gene sequence to identify crime scene DNA, paternity, genetic disease screening Gene Therapy – using viruses or bacteria to replace genes Cloning – Creating genetically identical organisms Tissue Culturing – grow human tissues & organs Drug Development – using biological processes in organisms to drugs or vaccines

Biotechnology In Microbiology Microbes are ubiquitous (!) Scientists can use microbes to solve a variety of human and environmental problems. Cleaning oil spills Decomposing waste in landfills or water treatment plants Specialty food products (yogurt, cheese, bread, alcohol, soy) Home and industrial cleaners

Biotechnology In Agriculture The oldest applications of biotech are found in agriculture. Early man used selective breeding (artificial selection) in both plants and animals to produce organisms with desired, useful traits. Modern agriculture is concerned with providing enough food for a growing world population. It uses genetic modification to: Increase crop yields (more food on less land) Improve the quality and nutritional value of food Improve the ability of crops to resist stresses such as weather, insects and disease.
