1 Biotechnology Using knowledge of the DNA code for practical applications

2 Genetic Engineering The process of making changes in the DNA code of living organisms Example: Inserting a gene that Glows in the dark. How does this work?

3 How can we insert genes? Make Sticky Ends Make Sticky Ends Cut Here And Here THEN Paste this Into this

4 Genetically Engineered Products Milk from Cows Engineered To produce Specific proteins Corn engineered With its own pesticide Rice engineered To produce All needed Vitamins & minerals

5 Production of Human Insulin Insulin regulates the blood sugar level. The gene for human insulin is inserted into yeast or bacteria, from which large quantities of the human insulin are manufactured http://publications.nigms.nih.gov/genetics/images/ch1_diagram.gif http://www.ingenious.org.uk/media/4.0_SAC/webimages/1032/1/10321271_3.jpg

6 Other DNA Technology DNA fingerprinting –Forensics or Crime –Paternity cases (or long lost relatives) –Endangered species trade Human Genome Project –Map of all 30,000 human genes –Compare diseases, treatments and genes for best therapy What is this?

7 DNA Fingerprinting Every individual (except identical twins) has a unique DNA fingerprint Once the DNA has been cut, it can be separated into bands (based on their size) by using gel electrophoresis. Example: –solve the mystery of It Takes a Lickin’ by visiting the following website: http://www.pbs.org/wgbh/nova/sheppard/lab01.html http://www.pbs.org/wgbh/nova/sheppard/lab01.html
