Biotechnology is the use of living things to make things that will be useful to us. This could include medicines, animals with certain traits, plants that grow quickly, or even complete organisms. http://www.geneticliteracyproject.org/2012/11/23/usda-urges-consideration-of-gmo- crop-insurance-organic-farmers-howl/Corn Crop (Jim Champion) CC BY-SA 2.0

There are several important areas of biotechnology. These include: selective breeding cloning genetic engineering Microsoft Office ClipArt

Selective Breeding Selective breeding - process by which people choose which traits they would like to have in the next generation of offspring. They then select the organisms, having those traits, to breed in order to produce offspring with those traits. An example of this is breeding “teacup” dogs. Breeders cross small dogs in an attempt to produce offspring that are tiny.

Cloning Genetic material is removed from an egg cell and replaced with the genetic material from a body cell of another organism. That egg cell then grows into an “exact” copy of the organism that is being cloned (the body cell donor). One example of this is Dolly the sheep.

Cloning http://en.wikipedia.org/wiki/Cloning#mediaviewer/File:Human_cell- line_colony_being_cloned_in_vitro_through_use_of_cloning_rings.jpg Paphrag CC BY-SA 2.5 Cloned in Hawa’ii in 2000, Cumulina was the first successful mouse clone. She lived until the ripe old age of two years and seven months, a victory for her researchers. http://www.businesspundit.com/20-animals-that-have-been-cloned/ Labs intend to modify pigs so that they can grow cells and organs that humans can use. Millie and her sisters (if you can call them that) were cloned in 2000 by a US-based company. These cows were cloned in 1998 and duplicated several thousand times. Made in Japan, the cows pave the way for other clones engineered to produce better meat and milk.

Genetic Engineering Genetic engineering involves directly changing the DNA of an organism. This could be adding or deleting traits (e.g. genes or groups of genes) on the DNA strand. Organisms produced in this way are referred to as GMOs, or genetically modified organisms. An example of this include some plants used for food, Glo-fish, and bacteria that can produce human insulin.
