Which of the following is NOT a way farmers would traditionally modify plants in the past?
transgenic manipulation
selective breeding
saving seeds
cross-pollinating

Nucleic acids
Lipids

Cisgenic
Transgenic
Why can Agrobacterium be used to genetically modify a crop?
Agrobacterium causes disease (attacks!) in plants.
Agrobacterium has the ability to transfer a portion of its DNA into plant cells.
The Agrobacterium carries the vector with the gene of interest & helps to incorporate its DNA with the crop's DNA.
All of the above!
Which would NOT be a reason to use GM crops?
Using GM crops can increase crop yields.
Using GM crops can reduce use of insecticide sprays.
Using GM crops may be able to feed more people faster.
Using GM crops can increase pesticide resistance in pests.
How might scientists check to make sure their GMO worked?
Add a fluorescent (glowing) gene (with the gene of interest) to see if the final product glows
Add another gene (with the gene of interest), like a resistance to herbicide gene, to test for its addition in the final product.
Add pests to the final product to see if they live or die!
All of the above!
