Which of these is NOT a use for DNA Fingerprinting?

• Identifying the person whose DNA was left at a crime scene

• Determining the father of a child

• Finding out the DNA sequence of a person

• Figuring out which species are more closely related

Why did scientists edit the genes of bacteria to produce insulin?

• Because the bacteria were diabetic

• Because bacteria have simple DNA that is easier to manipulate, making it easy to produce insulin in a lab

• Because bacteria's complex DNA was perfect for insulin production

• Because insulin has no use outside of a lab setting
