Explanation:

3. Scientists use it to detect and address diseases, create medicines, modify foods, to assess whether or not our food is safe to eat, it can also be used to determine if someone is innocent of guilty based on DNA evidence.

4. You can get results to see if theres a disease faster, so you have more time to find out how to treat the person. For example, a Profesor traveled to Africa during the ebola breakout, he realized the doctors there didn’t have the tools to detect and fight diseases, results had to take weeks to come back, and that wasn’t enough time for the patients and families who are suffering.

5. This is more of a "in your opinion" question. But, I thought they can help scientists get the results much quicker.
