Biotechnology • The use of living organisms to solve problems and make useful products. • Examples: crop plants and farm animals; using yeast to make bread rise.

Biotechnology • Many types of technology that uses: – Cells – Proteins – Genetics • Other fields use biotechnology, like health care, agriculture, genetics, and food science.

Selective Breeding • Breeding selected organisms to get offspring with certain traits. • Has been an important farming practice for many centuries.

Hybrid • Cross between two different species • Example: mule from donkey and horse

Genetically Modified • Organisms whose genes have been changed. • Used for: – Making medicines – Treating diseases – Improve crops Herbicide-resistant corn! Making insulin for diabetic patients!

Genome • Complete map or sequence of an organism’s DNA. • Scientists identify genes and DNA strands.

DNA Fingerprinting • Scientists collect DNA at a crime scene (blood/hair) and match the DNA to suspects, because each person has own unique DNA. • Part of “forensic testing. ”

Crop Yield • Biotechnology improves the crop yield. • Measure of how many crops are produced.

Ethics • Ethical Questions – deal with morally right or wrong issues. • Examples: Cloning; Genetic Modification.

Cloning • Produces an organism that is an exact genetic copy of another.

Bioremediation • Uses existing bacteria in the soil to clean up the environment. • Examples: oil spills, toxic waste.
