5. Explain how genetic engineers can use bacteria to help people with diabetes.
![Page 11: Advances in Genetics review questions](https://reader035.vdocuments.net/reader035/viewer/2022062217/56814e32550346895dbb9891/html5/thumbnails/11.jpg)
Answer
• You can insert the human gene for insulin into a plasmid of a bacterium. That bacterium will then produce insulin. Because it can reproduce quickly, it can make many more bacteria that can also make the insulin protein needed by people with diabetes.

10. How does the goal of hybridization differ from the
goal of inbreeding?
![Page 21: Advances in Genetics review questions](https://reader035.vdocuments.net/reader035/viewer/2022062217/56814e32550346895dbb9891/html5/thumbnails/21.jpg)
Answer
• In inbreeding, your goal is to make offspring with the same desirable traits as the parents
• In hybridization, you want to get an offspring that combines the desirable traits of each parent, but doesn’t have the negative traits.
