Objective 10.02

• Discuss the value of agricultural biotechnology applications related to the food, fiber, and natural resource systems.

Applications of Biotechnology in AgriScience

• One application of DNA matching is identifying parents of offsprings

• Genetic engineering was discovered by scientists in the early 1980s and was a breakthrough in modifying genetic makeup.

• Genetic engineering is the movement of genetic information in the form of genes from one cell to another.

Products of Genetic Engineering

• Insulin: one of the first commercial products of genetic engineering– Chemical used by people with diabetes– Produced by genetically engineering E.coli

bacteria

Products of Genetic Engineering

• Herbicide resistant crops are a product of genetic engineering

Products of Genetic Engineering

• BST (Bovine somatotrapin): increases milk production in dairy cattle– Result of genetic

engineering

Products of Genetic Engineering

• Lee-minus: a bacteria that was genetically altered to retard frost formation on plant leaves

Products of Genetic Engineering

• Other bacteria strains are under development to convert solid waste from humans and livestock into sugar and fuel
