1
Application of Genetic Engineering
2
Transgenic Organisms Transgenic: one organism contains genes from a different species. Genetic Engineering: moves a gene from one organism to another.
3
Fireflies and Tobacco Plants
4
Bacteria Bacteria as transgenic organisms Bacteria are used to produce
easy to grow reproduce fast Bacteria are used to produce insulin & cancer fighting substances materials for plastics & synthetic fibers compounds cheaply and in abundance
5
Genetically Modified Fish?
6
Transgenic Animals Used to study genes and improve food supply
Mice: to study human immune system Livestock: grow leaner and faster Chickens: resistant to bacterial infections In the future: sheep and pigs that have human proteins in their milk.
7
Transgenic Animals
8
Transgenic Plants In 2000, 52% of soybeans & 25% of corn were transgenic, or genetically modified (GM) produce natural insecticides resistant to pesticides Rice that contains Vitamin A Future: Antibodies Plastics Won’t rot and spoil
9
Transgenic Tobacco
10
Genetically Modified Organisms
11
Bt Cotton
12
Cloning Clone: a member of a population of genetically identical cells produced from a single cell. Easy to grow clone bacteria colonies, but difficult for multicellular organisms. Pro: save endangered species Con: genetic defects & health problems
13
Dolly In 1997, Ian Wilmut cloned a sheep, Dolly
Nucleus of an egg cell is removed & fused with another adult cell Embryo is placed in foster mother
14
Cloned Cattle
