10 Biology - Genetic Engineering - GMO or selective breeding?

Genetic engineering is when you

• Combine the DNA from 2 different organisms

• Breed from only your best animals

• Save only the best seeds

"Genetically modified" or "transgenic" refers to an animal that:

• Has DNA from another organism added (spliced) into its genome

• An animal that is a clone like Dolly the sheep

• Has been selectively bred for a certain trait

• Make them pest or herbicide resistant

• Make them more nutritious

• Make them drought resistant

• All answers are correct

A circular piece of DNA, found in bacteria, is called:

• A plasmid

• mRNA

• Ribosome

• Nucleotide
