1. Selective Breeding and Transgenics

2. Selective Breeding
Selective breeding is the breeding of individuals of desired traits, in order to combine desired traits in offspring.

6. Genetic Engineering (AKA gene slicing, AKA Recombinant DNA)
Adding a gene from a different organism to a new organism, so the new organism will express those traits.
Example: Bacteria producing insulin and medications

7. How it’s done
Restriction enzyme is added to both the donor DNA and the host DNA. (Host DNA is often a plasmid—a ring of bacteria DNA)
Bacteria are often used to make insulin and medicine because they are single celled (easy to manipulate), have a single ring of DNA (plasmid) and reproduce asexually and rapidly.
