1. DNA Technology
Chapter 13

2. Genetic Engineering
Genetic Engineering: form of genetics in which scientists directly manipulate genes
Uses “DNA technology”
Purpose:
Cure disease
Treat disorders
Improve nutrition & lifestyles

3. Manipulating Genes
Restriction Enzyme: cuts DNA into smaller pieces to be worked with
Cuts at specific sites (i.e.: “CTTAAG”)
Once cut, may remove harmful gene or insert donor gene
Result is Recombinant DNA

4. DNA Fingerprints
DNA Fingerprint: a pattern of bands made up from an individual’s DNA
Arranged in columns
Used to identify an individual (in crimes)
Used to establish relatives

5. Human Genome Project Goals: Began 1990; Completed 2003
1) To determine nucleotide sequence of the entire human genome
2) To map the location of every gene on every chromosome
Began 1990; Completed 2003
Used to help cure and treat genetic disorders
Cystic fibrosis, Muscular dystrophy, etc.

6. Practical Uses of DNA Technology
1) Vaccines
A solution that contains a harmless version of a virus or bacterium
2) Herbicide-resistant crops
Strains of wheat, cotton, & soybeans engineered to be resistant to weed killer
3) Food Supply and Nutrition
Engineered to ↑ yield & preservation
