What is Genetic Engineering? Gene manipulation Genes are engineered into organisms such as microbes (bacteria) for mass production Insertion of select genes into organisms to improve their genotype

Identify the procedure of genetic engineering? 1. Isolating genes (cut it from DNA) 2. Recombination (linked to larger section of modified bacterial DNA)

Identify the procedure of genetic engineering? 3. Transformation (inserted into target cell) 4. Screening (used to check if gene of interest is presented)

Identify the procedure of genetic engineering? 5. Induction (attach a promoter, extra set of base pairs that control the activation of the gene)

Activity Time!!!!! In groups of four

How is genetic engineering applied in agriculture? Crops have been developed that resist insect damage and spoilage Some species of plants have the ability to kill off weeds around them

How is genetic engineering applied in agriculture? This would cut down on the level of herbicides sprayed Scientists inserted genes that prolong the shelf life of fruit and vegetables

What are some uses of genetic engineering in agriculture? Black walnut has the ability to kill off certain species that grow near it Tomato has a longer self-life with delayed ripening Corn-borer-resistant corn has a pest-resistant trait

What are some uses of genetic engineering in agriculture? Strawberries can withstand freezing temperatures Potatoes absorb less oil when fried thanks to their high starch content Crops can also be genetically engineered to be resistant to frost damage

How do genetically engineered crops help society? Plants can help in producing human antibodies for anti-cancer and anti-virus drugs Some consumers are fearful of the compounds and chemicals used to make it

Your Life…Your Choice!!! If you had a choice between a regular tomato and a genetically modified tomato, which would you choose? Does it really matter to you?

Exit Slip List two ways that genetic engineering is applied in agriculture. List three uses of genetic engineering in agriculture learned from today’s class.
