Which enzyme would be added to fruit in order to create a larger volume of juice out of the plant cells?

• Amylase

• Maltase

• Pepsin

• Pectinase

This is the practice of inserting the DNA of another species into an organism's DNA so that the organism gains a new trait.

• Cloning

• Gel Electrophoresis

• Genetic Engineering

• DNA Fingerprinting

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
