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

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

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

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?

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
