What is an ethical issue with gene therapy?

• It may be used for unfair reasons

• It can only be used on crops

How does DNA help forensic science?

• It helps identify suspects

• It replaces fingerprint tests

• It finds lost family members

• It predicts a criminal’s actions

Why is gel electrophoresis used?

• To make more copies of DNA

• To separate DNA by size

• To create new DNA strands

• To study living bacteria

One product of biotechnology is genetically modified foods. Some people are concerned about these foods because–

• they are usually more nutritious than naturally produced foods.

• allergens from one food may be accidentally transferred to a different food.

• unmodified crops usually grow more slowly than genetically modified crops.

• the production of these foods increases the biodiversity of organisms on Earth.
